    Abstract

    Sreenivasa Rao Jarapala

    Green leafy vegetables (GLVs) are pigment-rich and nutritionally relevant functional food sources with unique phytochemical constitution that includes carotenoids. Carotenoids and their geometric isomers protect cells from oxidation and cellular damages. Cooking processes that involve factors such as temperature, light and alteration in moisture content generally promote either isomerization (trans to cis form) or oxidative degradation of carotenoids to epoxides. Studies pertaining to the effect of cooking methods on dietary carotenoids and their geometric isomers are inadequate in Indian foods. The extent of carotenoid isomeration were evaluated in GLVs such as amaranth (Amaranthus gangeticus), spinach (Spinacia oleracea) and curry leaves (Murraya koenigii) subjected to domestic cooking methods of microwave, sautéing, pressure cooking and deep frying in oil for time durations of 8 and 12 minutes, either with and without lid covering. The isomers of carotenoids were quantified by high performance liquid chromatography (HPLC) using vydac column (RP-C-18) with 100% methanol for first 5 minutes and methanol: chloroform (96:4) for the subsequent run as gradient mobile phase. Tran’s β-carotene content in amaranth ranged from 5525 to 6375 µg/100g upon boiling without lid and microwave cooking. 9-cis isomer of beta carotene is the predominant geometric isomer formed during cooking in all the GLV studied (Amaranth: 423 to 620, Spinach: 377 to 443, Curry leaves: 562 to 687 µg/100g). 13 cis isomers also formed in the processed GLV samples (22 to 375 µg/100g). 15 cis beta carotene was observed in few food samples during processing and not observed in some of the methods which processed. The retention percentage of all Trans and cis beta carotene was also studied. These isomers of beta carotenes were also for the precursors of Vitamin A. The changes in the contents of Trans and cis isomers of carotenes in GLVs in correlation to various cooking methods are discussed which would be valuable for food researchers, nutritionists and health practitioners in promoting nutritionally balanced diets and minimize vitamin A deficiency in Indian contest.

    Background : In India, the recent ICMR study revealed that the prevalence of diabetes (both known and newly diagnosed) in 4 regions of the country: 10.4 per cent in Tamil Nadu, 8.4 per cent in Maharashtra, 5.3 per cent in Jharkhand, and 13.6 per cent in Chandigarh (Anjana et al., 2011). High prevalence of prediabetes observed in many South Asian countries highlights a potential indicator of further progression of the diabetic epidemic in the region. Unless appropriate action is taken, this will place an economic burden. Hence a food based approach was planned to reduce the incidence of prediabetics. The main aim of the present study was to investigate the hypoglycemic effect of bitter gourd (Mormordica Charantia L.)among prediabetics. Materials and Methods: A single blinded, placebo-controlled, randomized, cross-over designed intervention study was conducted with freeze dried bitter gourd powder (2.5 g) to find out its hypoglycemic effect. In the first phase Group 1 (AB) started the bitter gourd juice (A) intervention followed by placebo(B), while the Group 2 (BA) started the supplementation with placebo(B) followed by bitter gourd(A). The intervention continued for a period of eight weeks. Between the two arms, 4 weeks were left as wash-out period. This is to minimize the carry-over effect of one phase to the other. Cross over was done after this washout period. Results: The mean initial fasting blood glucose level of prediabetics in AB group was 110.66 mg/dl which got reduced significantly (p<0.01) to 99.86 mg/dl at the end of bitter gourd intervention. In the case of BA group the placebo treatment did not bring forth any appreciable change in FBG where as the bitter gourd treatment was found to have a significant (p<0.01) impact. No serious adverse effects were observed. Conclusions: The present study proves that the consumption of bitter gourd juice prepared with 2.5 g freeze-dried bitter gourd powder (50g of the vegetable) reduced the fasting blood glucose and total cholesterol level among the prediabetics. Keywords: Hypoglycemia, prediabetes, bitter gourd, diabetes

    Potential spoilage organisms capable of growing and causing sufficient changes in fish to warrant it being described as spoiled have their varying origins and habitat. Fresh Fish caught from the dam are assumed to be hygienic. Fresh fish samples were obtained from Gubi dam. The fish samples were weighed and halved from the head to the tail to get an even fillet distribution. The samples were blended with diluents to obtain a homogenous suspension. The diluent was used for serial dilution before cultivation and isolation. Well separated colonies were sub cultured on fresh culture and subsequently characterized. Smear was made by emulsifying small quantity of the bacteria colony in a drop of distilled water on glass slides. Gram staining was carried out and the stained slide was then examined. Biochemical tests were also carried out the bacteria implicated were; Micrococcus, Serratia, Pseudomonas, Staphylococcus, Proteus, Bacillus, Aeromonas, Acinetobacter. The organisms are of the pathogenic and Enterobacteriacae origin. And the presence of pathogenic species is independent on a number of factors including the sources of nutrients used in the fish rearing, the extent of feeding, the population density, method used to harvest. Key words: Gubi Dam, Fresh fish, Spoilage.

    Rice varietyViz., IET 7191 affected by grain discoloration was selected to study its qualitative characters. Discoloration was resulted due to infection by fungiViz.,Bipolaris oryzae, Pyricularia oryzae, Fusarium moniliforme, curvularia lunata, Trichoconiella padwickii, Cladosporium, Apergillus, Phomasp,Rhynchosporium oryzae, Alternaria alternata, Nigrospora oryzae, Absidia sp. etc.Rice grains were grouped in to four categories based on extent of discoloration viz., less than 1 per cent, 1-25 per cent, 26-50 per cent and more than 50 per cent discoloration. Grains under each category were subjected to milling and polishing. After milling and polishing kernels were plated on moist blotters to know the effect of milling and polishing onseed mycoflora. Only fungi viz., Bipolaris oryzae, Fusariummoniliforme, curvularai lunata, Trichoconiella padwickii, Cladosporium, Apergillus, and Alternaria alternata were observed on rice kernels after milling and polishing. Kernels after milling and polishing under eachcategory of discoloration were subjected tophysico-chemical compositions. As the level of discoloration increased from less than 1 per cent to more than 50 per cent discoloration, 1000 kernel weight decreased from 20.0 to 16.4 per cent, moisture content from 6.5 to 5.0 mm, raw rice length from 6.15 to 6.0 mm, raw rice width from 2.50 to 2.32 mm, length- width ratio increased from 2.46 to 2.58. Amylose content decreased from 24.0 to 9.0 per cent, total nitrogen content from 1.46 to 0.82 per cent, crude protein content from 9.12 5.16 per cent, reducing sugars from 34.75 to11.01 u moles, non reducing sugars increased from 0.26 to 93.95 u moles and total sugars from 35.01 to 104.76 u moles per gram of dry weight of rice kernels, while alkali value was not affected by discoloration.

    The quality of commercial virgin olive oils is guaranteed by chemical and organoleptic (Panel Test, PT) analyses. The aim of this research was to transform VOCs perceived by the human olfactory sense in a meaningful spectra profile useful to distinguish oil trade classes (EVOO/ Not EVOO), and to grade EVOO, based on the intensity of the main positive (fruity) attribute using a fast and not expensive VOCs test, also useful to promote at consumer's level the sense of quality by smell and lack of defective odors. Extensive surveys were carried out on 150 olive oil samples from different countries, processed as monocultivar or blend, acquired to producers or in the stores. Samples were analyzed by a PTR-ToF-MS as its high resolution coupled to a rapid screening power of samples, easy to handle and without any manipulation, while a PT recognized as EVOO 68/150 samples, characterized by different "fruity" flavor intensity. A principal component analysis (PCA) of the whole PTR-ToF-MS data clustered the samples in two main groups, including the 68 samples classified by the PT as EVOO, without any defective odor, and the 82 classified as not EVOO, respectively, with only a few partially overlapped. A PLS-DA model correctly classified EVOO/Not EVOO spectra as resulted by PT, confirming the high confidence level (95%) in utilizing analytical spectral data in helping PT. A Fuzzy Clustering applied to the spectral data confirmed the 3 group of EVOO recognized by the Panelists, allowing to grade the samples by "fruity intensity" (1-3 = light, 4-6 = medium, 7-9 = intense). In conclusion, throughout adequate DB the high quality of each oil sample can be predicted in any step of commercial chain of virgin olive oils processing, by a rapid and convenient way, so to define and preserve the high quality products.

    The taxifolin (TXF) is recently rediscovered as a highly potential antioxidant with reported therapeutic properties. However, the data about possible protective properties of TXF and information about its stability is scarcein meat sausages. The aim of this work was to evaluate the antioxidant and antimicrobial activity of TXF when it is used together with ascorbic acid (AA), linalool, dipeptide carnosine(CAR), lactic acid (LA) and their mixtures indry-cured pork sausages during storage.Also, possible biochemical interactions among these bioactive substances on cell apoptosis and proliferation-related variables in the human cervical cancer HeLa cellshave been investigated. The activity of tested materials against lipid and protein oxidation, the grower of microorganisms and stability of TXF has been evaluated in dry-cured sausages after 0, 30, 60, 90 and 150 days of storage.The evaluation of TXF stability has been performed by UHPLC analysis.On the 150 day of storage the total amount of TXF was higher in sausages with TXF+LA (40% less) and with TXF+AA (54%less), comparingwith the 1stday of storage. Meanwhile, the retained amount of TXF in the samples without acids was 60% less, comparingwith the initial amount. TXF antioxidant capacity (DPPH) was higher in the samples with LA or AA and effectively inhibited the processes of lipid peroxidation as well as slowed down the rate of lipolysis. Moreover, TXF mixtures with acids reduced the number of total aerobic bacteria, mold and yeast during storage of sausages. The treatment of combination of the three compounds (TXF, CAR and AA or LA) on HeLa cells (by MTT method)resulted in a significantly lower percentage of live cells number than treatmentonly with individual substances in different concentrations (P<0.05). The outcome of this study can help develop new meat products with better nutritional quality and beneficial health properties.

    The commonly used polycarbonate bottles contain Bisphenol A (BPA). Exposure to BPA causes cancer and mimics the hormonal system in pregnant women and children. Only recently, the polycarbonate bottles are banned, in India. As an alternate to BPA, Polypropylene (PP) is used in baby bottles, drinking straws and microwavable wares. The major chemical migrants in PP namely, Octa decyl 3(3-5 di-tert-butyl-4-hydroxy phenyl) and propionate/ Iganox 1076 are known to cause cancer of liver, kidney and lungs in experimental animals. Hence the present study was conducted to synthesize a protective coating from four medicinal plants, of which Glycyrrhiza glabra was found to possess the highest antioxidant, antimicrobial and anticancer properties. The particle size, zeta potential and EDAX of nanoparticles from Glycyrrhiza glabrawere 34.7nm, -24.7mV and 2.60 percent of silver respectively. These properties along with the phytochemicals, augmented the chelating and antimicrobial potentialities of the plant extract. Thin layer chromatography of Glycyrrhiza glabra showed the presence of phenolic compounds and antioxidant activity of 520 µg. FTIR results revealed chlorohexidine salts peaks at 1157 cm-1, which indicate breaking up of lipopolysaccharide. Chlorohexidine is a cationic biocide that damages the outer membrane of gram negative bacteria. Secondly the peak 1442.72 cm-1 corresponds toC=O stretch which shows remarkable intensity changes, revealing better antimicrobial potentials of the encapsulated nanoparticle compared to the raw plant extract. The GC/MS identified the following compounds namely tetradecanoic acid, Z, Z 2,5 pentadecadiene-1-ol, cis-9,10 epoxy octadecan-1-ol, 9 octadecenal and hexadecanoic acid.Hence, Glycyrrhiza glabra nanoparticles were coated onto the feeding bottles and the foods stored in them were tested for their shelf-life for three hours. Nano coats of Glycyrrhiza glabra were also tested on pet bottles and ziplock covers and foods tested over 10 days. Milk stored in feeding bottles recorded a maximum microbial inhibition of 84 percentage and diluted lemon juice showed no microbial growth of S.dysenteriae.On 10th day, nanocoated zip lock covers and PET bottles showed a maximum microbial inhibition of 38, 63 and 83 percent and 57, 68 and 88 percentage against E.coli(MTCC 40), S.enterica (MTCC 3219) and S.dysenteriae (PSGIMS & R) respectively. The MTT assay of Glycyrrhiza glabra nanoparticles showed a maximum apoptosis of 50 and 48 percent against Hela and liver carcinoma cell lines respectively. The gel electrophoresis has led to a longer tail DNA damages with the Hela and carcinoma cell lines, compared to the control and marker. Therefore, nanocoats of Glycyrrhiza glabra could be used for effective protection against oxidative damage, diarrhea and cancer.

    Small millets have both preventive and curative properties good for addressing constipation, heart problems and type 2 diabetes suitable for preventing obesity. Small millets include, finger millet (Eleusinecoracana), Kodo millet (Paspalumscrobiculatum), little millet (Panicumsumatrense), foxtail millet (Setaria italic), proso millet (Panicummiliaceum), and barnyard millet (Echinochloacolona) and each one of them has special nutritional benefits.Small millets, perform well in marginal environments having superior nutritional properties, including high micronutrient and dietary fibre content, and low glycemic index. Despite their superior nutritional qualities and climate resilience, cultivation of small millets in India declined from 7.22 million hectares to 2.29 million hectares between 1961 and 2009, this decline in production and consumption of small millets mainly due to limited productivity, high drudgery involved in their processing, negative perceptions as a food for the poor. Through context‐specific production technologies, creating decentralized processing infrastructure and local market development it is possible to bring back small millets to farms and food baskets on a wider scale. Among the children under the age of five years in India, 48 percent have stunted growth and 43 percent are underweight, likewise chronic and non‐ communicable diseases like Type‐II diabetes and impaired glucose tolerance are on the increase.The primary factors responsible for the steep decline in the production and consumption of small millets in India are; Low productivity, high labour intensity, drudgery of agricultural operations and lack of attractive farm gate prices. Promoting small millets as cropping systems, support for timely availability of quality seed, Large scale capacity building to farmers on location specific improved production practices, creating post‐harvest infrastructure and marketing initiatives are some of the strategies for enhancing production. Besides, therapeutic products targeting elites need intensive efforts for quality maintenance, consumption promotion through public support and supplying ready to cook small millet products will promote small millets in the baskets of urban elites are discussed in this paper.

    Malt extract is a source of nutrition, energy, vitamin B and sometimes it is used as a “tonic”. The purpose of this presentation is to show the effect of using malt extract in yogurt production and evaluate the end product in terms of health. Malt extract is a very valuable nutrient since it contains easily digestible carbohydrates like dextrin and maltose, protein decaying products, enzymes and vitamins. Malted milk is used most widely. When malt and milk are combined during the milk production process, the fat globules are encapsulated and become protective against the oxidative stress. In recent years, because of this suitability of malt and milk, they were started to be used in ice cream and cheese industry. Malt extract-added yogurt contains water-soluble fructans, fructo-oligosaccharides and some nutrients which exist in malt contents and are considered as prebiotics. The presence of these substances in food makes it a functional food. By adding the malt extract, the appearance, flavor, texture and taste of the yogurt will be optimized. Malt extract can be used in production of yogurt and it can be acceptable and supporting in the health perspective. Keywords: Malt extract, yogurt production, prebiotic, functional food

    Background: The gastrointestinal tract is the portal for the entry of dietary nutrients, and a number of intestinal hormones such as ghrelin, glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) are involved in their absorption and storage. A direct effect on adipose tissue is highly likely if specific receptors for these peptide hormones can be identified in the tissue. While specific receptors for GIP have been reported in adipocytes, studies have been inconclusive with regard to GLP-1 and nothing is known with respect to ghrelin. Aims: To determine: (1) if the genes for the ghrelin, GLP-1 and GIP receptors are expressed in mouse (3T3-L1) and human (Simpson-Golabi-Behmel syndrome; SGBS) adipose tissue cell culture systems; (2) at what stage of adipocyte maturation, receptors for ghrelin, GLP-1 and GIP are expressed; (3) to assess whether receptors for GIP (GIPR), GLP-1 (GLP-1R) and ghrelin (ghrelinR) are expressed in each of the major mouse adipose tissue depots. Outline methods: Species specific primers were designed and RT-PCR was performed on RNA extracted from mouse adipose tissue depots, and 3T3-L1 and SGBS cells. Expression of the genese for GIPR, GLP-1R and ghrelinR was examined. Results: (1) GLP-1R, GIPR and ghrelinR mRNA was detected in several tissues, including four major white adipose tissue depots in mice. (2) 3T3-L1 and human SGBS adipocyte cell culture studies show that GIPR, GLP-1R and ghrelinR genes are expressed late post-differentiation. Conclusion: GIP, GLP-1 and ghrelin receptors are expressed in the major mouse fat depots as well as mouse and human adipocyte cell culture systems. Hormonal signals from the intestine may influence adipocyte function.

    Requiring little or no sample pretreatment, ambient mass spectrometry allows the direct characterization of raw samples at molecular levels under an open atmosphere[1]. Due to the unparalleled sensitivity and specificity, ambient mass spectrometry has been increasingly considered for wide applications in food science and industry. In virtually any type of food samples could be directly analyzed using mass spectrometry powered by one of the currently available ambient ionization techniques. Typically, trace amounts of analytes on solid foods could be rapidly detected using either desorption electrospray ionization (DESI), direct analysis in real time (DART) or desorption atmospheric pressure chemical ionization (DAPCI)[1, 2]. Both volatile and non-volatile analytes could be detected by ambient ionization techniques for surface analysis. For more consistent results, heat, solvent extraction or gas liberation would be preferably used during the desorption/ionization process for detecting analytes of low volatility, particularly on viscous food surfaces (e.g., cheese, icy meat etc.). Alternatively, liquids and gaseous samples could be real time monitored using extractive electrospray ionization (EESI) or its derivates[3, 4]. Rapidly revealing the chemical information inside bulk foods is of paramount importance in food science and industry. Herein internal extractive electrospray ionization mass spectrometry (iEESI-MS)[5] was developed to probe the molecules inside a 3-D bulk food sample requiring no mashing/grinding the sample or matrix clean-up. To date iEESI-MS has been applied to the qualitative characterization of various biological samples (tissues, fruits, vegetables, etc.) and accurate quantitative analysis of 6 β-agonists in bulk meat samples, opening new possibilities in food science and industry. In this talk, the principle of ambient mass spectrometry, typical instrumental setup and applications would be systematically reviewed, the advantages and shortages of ambient mass spectrometry for food analysis would be mentioned, and the impact of ambient mass spectrometry on food industry would be briefly discussed.

    The United States Food Safety Modernization Act (FSMA) was signed into law in 2011. FSMAaims to better protect public health by strengthening the food safety system. It focuses more on preventing food safety problems rather than relying primarily on reacting to problems after they occur. For the first time, the US Food and Drug Administration (FDA) will require comprehensive, science-based preventive controls across the food supply. The law directs FDA to develop a comprehensive plan to expand the capacity of foreign governments and their industries. One component of the plan is to address training of foreign governments and food producers on U.S. food safety requirements. The Joint Institute for Food Safety and Applied Nutrition (JIFSAN) at University of Maryland (UMD) was established by the university and FDA in 1996. The UMD and FDA partnership has provided a dynamic program that integrates research, education and outreach that enhance FDA’s ability to address safety concerns and public health issues related to foods. JIFSAN has also developed and delivered education and training programs to support food safety capacity building in more than 50 countries. These programs include food safety best practices at production, risk analysis, preventive controls and hands-on laboratory techniques. Over 8,000 food safety professionals have participated in the programs.JIFSAN will continue to strengthen the established programs and work on new initiatives to be identified that are important to support FSMA in enhancing science-based preventive control standards to strengthenthe food safety system and improve worldwide health.

    The incidence of food-borne diseases has been increased over the last decade and has become a major public health worldwide. Among 31 identified food-borne pathogens, non-typhoidalSalmonella and Campylobacterspp. are the most common detected bacteria in food-borne incidents. Poultry meat, eggs and products contaminated with Salmonellaand/or Campylobacterare the major source of food-borne diseases in humans. The aim of this study was to developreliable and rapid diagnostic tests that can detect and differentiate Salmonellaseroptypes and Campylobacter jejuni from Campylobacter coli without requiring DNA sequencing. Specific primers were used to amplify targeted genes of different Salmonellaand Campylobacterreference strains and clinical isolates from commercial poultry farms. PCR products were subjected to high-resolution melt curve analysis and Salmonellaor Campylobacterisolates were differentiated based on their HRM curves. Analysis of the nucleotide sequences of the amplicons from selected isolates confirmed that each melting curve profile was related to a unique DNA sequence. The relationship between Salmonella or Campylobacterreference strains and tested specimens was also evaluated using a mathematical model without requiring visual interpretation of HRM curves.In addition, the potential of the PCR-HRM curve analysis was evaluated for genotyping of additional Salmonella isolates from different avian species or human Campylobacter isolates. The findings indicate that PCR followed by HRM curve analysis provides a rapid and robust technique for genotyping of Salmonellaand Campylobacterisolates in about 6 hours. Applications of PCR-HRM in identification of otherpathogens,important in food safety will be discussed.

    Dates (Phoenixdactylifera(L.) are extensively produced and consumed in Middle East. Dates flesh is consumed as a food while pits are thrown as waste or used as animal feed. Date pits comprise of 10-15% of total fruit weight. Date pits are rich source of dietary fiber (52%). Pits can be used in different types of food products to improve their dietary fiber contents. Bread loaves were prepared with acceptable sensory and rheological dough properties when date pits powder was replaced with wheat flour up to 12% level. The pasting properties of flour blends were also affected in the presence of date pits. Date pits pudding was also prepared and compared with commercially available chocolate pudding. Acceptable sensory and rheological attributes were observed in high fiber date pits pudding samples. Hardness and spread factor of cookies also increased in the presence of date pits powder. It can be concluded that date pits can be used as a cheap source of dietary fiber in different products without promising their quality attributes. The presence of good quality oil in date seed powder can also enhance the nutritional value of these food products.

    The effect of processing on the quality properties of cassava and its starch was reviewed. Cassava (Manihot esculenta Crantz) is a broadly cultivated root crop and mostly consumed in developing nations. Cassava can be processed into flour, chips and starch for subsequent use in food production. Fermentation, boiling, drying, steaming, baking, blanching, frying and parboiling are some of the methods of processing cassava roots. These processes lead to a reduction in its cyanide content and other effects on cassava quality. The use of native cassava starch in food industry applications cannot be over emphasized; however, a major factor militating against its use is the finite imbalance in its structure and properties. As a result of this, native starch from cassava requires some form of modification to enhance its quality in terms of structure and functionality.

    Mungbean is the third most important pulse crop in India. Among the fungal diseases, powdery mildew, anthracnose, Cercospora, web blight and dry root rot are the most prevalent. Apart from diseases some fungi are also causing qualitative and quantitative loss in storage.The study was conducted to know the seed mycoflora associated with mungbean and their management. Seeds samples collected from different districts were plated on moist blotters. Twelve fungi belonging to ten genera viz., Aspergillus niger, Alternaria alternata, Aspergillus flavus, A. candidus, Penicillium notatum, Rhizopus stolonifer, Cladosporiumsp., Fusarium oxysporum, Mucorsp., Curvularia lunata, Macrophomina phaseolina andChaetomiumglobosumwere observed from seed samples. Management of seed mycoflora was studied by different seed treatment methodsviz., physical, chemical and biological methods. Seeds treated with hot water at 45 °C for 30 min and 50 °C for 20, 25 and 30 min reduced seed mycoflora. Seed treatment with dry heat treatment at 50 °C for one hour effectively reduced the seed mycoflora. Seed exposed to solar heat treatment between 12-2 pm effectively reduced the seed mycoflora. Seed treatment with captan recorded the maximum inhibition of seed mycoflora (78.68%) followed by carbendazim (68.30 %), thiram (65.57 %), chlorotholonil (62.29 %) and vitavax power (62.84 %) at the rate of 4 g kg-1 of seed.

    Rain induced fruit cracking is an important problem in sweet cherry industry, causing loss up the 90%. Recent studies have suggested that a primary cause of fruit cracking could be the increase in fruit surface area during fruit development in the absence of deposition of cuticle membrane (CM) deposition. Abscisic Acid (ABA) and Methyl Jasmonate (MeJA) are phytohormones associated with stress tolerance, cuticle wax biosynthesis and fruit ripening. The objective of this research was to evaluate the effects of exogenous ABA plus MeJA applications on several quality parameters of sweet cherry fruits (cv. Bing). The application of theses hormones at different fruit development stages increased differentially the fruit cracking tolerance and fruit color at the ripening stage, affecting the soluble solids content, malic acid concentration and fruit cuticle resistance.

    In recent times, the benefits of edible coatings have been studied to maintain quality and prolong the post-harvest life of fresh fruits and vegetables. Its use is due to its ability to waterproof the fresh product by decreasing itsmoisture loss, regulating the oxygen uptake, and consequently, reducing its respiration, retarding ethylene biosynthesis and decelerating the oxidative reactions. The effects of soybean oil content and homogenization pressures on the physicochemical properties of alginate-based coating-forming nanoemulsions were evaluated. Coating-forming emulsions were developed based on alginate (1.0% w/v) and soybean oil (0.5%, 1.0% and 1.5% v/v) and using three homogenization pressures (50MPa, 100MPa and 200MPa). Emulsions were characterized in terms of droplet size, polydispersity index, ζ-potential, rheological behavior, and surface tension. Wettability was evaluated on the cherry tomato epicarp by measuring the critical surface tension and contact angle. Emulsions with smaller droplet size, lower polydispersity index, and higher ζ-potential were improved by increasing the homogenization pressures. Emulsions viscosity decreased when the homogenization pressures were increased for all soybean oil contents. Emulsion wettability improved with soybean oil content and by increasing the homogenization pressures. Incorporating soybean oil and using 200MPa of homogenization pressure produced emulsions with better functional properties, which could be used as a coating for fruit and vegetable products.

    Background and Objective: Cassava is an essential foodstuff in the tropical regions of the world. It is high in calories and also a very good source of revenue for many countries. Present study focused on optimizing quality of cassava (UVLNR 0005) flour in terms of color and thermal qualities. Materials and Methods: A central composite rotatable drying experiments comprising of two factors: drying temperature (60-70°C) and drying time (15-20 h) was designed using Stat-Ease design expert software. The software was also used to carry out one way analysis of variance (P < 0.05), regression analysis, optimization of color and thermal properties and obtain contour plots for interactions between the drying conditions, color and thermal properties. Results: Results indicated that the drying conditions used in this study had no significant effect on color and thermal properties of cassava (UVLNR 0005) flour. The range of L*, a *, b*, hue, chroma and WI were 87.67-93.57, -0.27-1.1, 8.4-11.83, 84.87-91.5, 8.4-11.87 and 82.88-89.42 respectively. The onset, peak, conclusion temperatures and enthalpy of gelatinization ranged between 93.68 to 114.21°C, 100.35 to 118.49°C, 108.73 to 123.51°C and 3.74 to 11.54°C respectively. Mathematical models obtained for the prediction of color and thermal properties at different drying temperatures and time were characterized with insignificant (P > 0.05) lack of fit test and high regression values. Drying conditions of 65.34°C drying temperature, 16.48 h drying time were found optimum for product quality at a desirability of 0.78. Conclusion: It was concluded that use of the optimum drying conditions obtained in this study for drying cassava chips can help preserve the color and thermal qualities of cassava flour.

    The concept of renewable energy and waste recycling has recently received a lot of attention. Dairy wastewater and by-products, if not handled properly, are huge pollutants and at the same time, they are suitable materials for producing renewable energy – bio methane.The aim of this study was to assess the potential of utilizing Lactobacillus delbrüeckii spp. bulgaricus in the acidification stage in order to increase the yield of bio-methane. Using the nuclear magnetic resonance was determined that dairy wastewater is a good source of important bio-refinery relevant compoundssuch aslactose, lactic, acetic and citric acid, amino acids, alcohols, organic acids and others, therefore wastewater has a potential to be utilized during fermentation as nutrients source. The efficiency of the methanogenesis process and the biogas yield is significantly affectedby the fermentation protocol and the wastewaters sample utilized.During the one-stage biogas production, lactic acid bacteria were not added to the wastewater. During the two-stage biogas production, acetogenesis and methanogenesis occurred separately with the addition of L. delbrüeckii during the acetogenesis stage. The separation of acetogenesis and methanogenesis in a two-stage process is preferable,as it increases methane content.The highest yield of methane was obtained from wastewater upon two-stage fermentation (76% two-stages compared to 38% one-stage). Therefore, L. delbrüeckii have the potential to be utilized to ferment dairy wastewaters and produce methane. Such treatment of wastewater not only produces methane, but also decreases the polluting effect of the waste streams, by reducing the chemical oxygen demand and biological oxygen demand to 0.199 and 0.031 g/l, respectively.The content of H2S in biogas from the wastewater samples varied from 0 to 252.5 ppm and isdependent on the fermentation protocol and the wastewater sample utilized.

    This study attempts to analyze the karyotype and chromosome structure in Ten populations of Camelina sativa in different part of Turkey.Pre-treatment, fixation, hydrolysis and staining were conducted using root meristem and then microscopic samples were prepared and studied. The results showed that in all studied cells of each population, the basic chromosome number was 2n=40 and all of them were diploid. Karyotype analysis of each population was conducted separately and several indices including length of the chromosome, length of the long arm, length of the short arm and centromer index were determined. The length of chromosomes in all populations was estimated as 0.64-2.08 micrometers. The longest chromosome was observed in chromosome number 1 from population 1 and the shortest one was related to the chromosome number 20 from population 7 in haploid karyotyping. Key words: chromosome, cytogenetic, camelina sativa, karyotype

    The snail (Helix sp.) belong toinvertebrate kingdom, Mollusca phylum (Teomophidea),Gastropoda class and mollusca anivalve.This genus live in forests and moist regions and feed from leaf,wood and vegetable containing a lot of cellulose.The digestive system of this snail have special enzymatic components for digesting cellulosic materials. Chromosomal studies and karyotypes analysis using different methods of staining (Aceto carmine, Aceto orcein, feulgen and etc.) have some problems such as chromosomal size, amount of tannins and difficulty of contrast in chromosome detection depending on species characters. Enzymatic components of the snail stomach have some effects on cytoplasmic and cell wall digestion. We used these components for easy squashing and perfect chromosome separation in two species of secale. In order to use enzymatic component this snail were collected from Arasbaran forests (North West of Iran), the enzyme extracted and kept in freeze condition. Seeds of two species of rye (Secale cereal & S.montanum) prepared from national plant Gene bank of Iran. When the seeds were germinated the root tips pretreated in α-Bromonaphtalin solution and stained by using aceto-iron hematoxillin. Then the extracted enzyme of snail stomach were used for clearing cytoplasm and softing cell walls and to obtain sufficient squashing and chromosomes spread. The results showed that using the enzymatic component of snail stomachwere very effective in squashing stage, and obtaining good metaphase plates, the chromosomes were counted and distinguished very clearly. This two species had 2n=2x=14 chromosomes and are diploid. Both two species had pair satellited chromosomes; the satellites are located on short arms of chromosomes.
