ThesisItem Unknown DEVELOPMENT OF PROTEIN RICH EXTRUDED PRODUCT FROM BUCKWHEAT (Fagopyrum esculentum) AND GREEN GRAM (Vigna radiata)(UNIVERSITY OF AGRICULTURAL SCINCES BANGALORE, 2024-02-11) DEVELOPMENT OF PROTEIN RICH EXTRUDED PRODUCT FROM BUCKWHEAT (Fagopyrum esculentum) AND GREEN GRAM (Vigna radiata); Viresh KumargoudaWith the increased modernization people’s perception towards the food habits too taking a leap that people prefer foods that are instantly be prepared along with nutritional aspects. Food products with high nutritional value with great taste to satisfy consumer needs are the need of the hour. Foods with low glycemic index and nutritionally rich are in great demand for the people involved in intense physical activities. The present study was carried out to develop cold extrudates (RTC) from buckwheat and green gram. Cold extruded products were developed by incorporation of buckwheat and green gram flour with wheat flour at varying levels. The blend was cold extruded at optimized extrusion conditions and the resultant pasta samples were assessed for their sensory and cooking characteristics. Pasta incorporated with composite blend (100 %) containing 40 % buckwheat and 10 % green gram and 50 % wheat flour was found to have optimum cooking characteristics and readily acceptance than other combinations. Product is packed in metalized polyester (50 μm) packaging material and kept at ambient conditions for three months to evaluate the storage behavior of the product. The parameters defining the quality i.e., moisture content, free fatty acid, peroxide value, colour, sensory evaluation and microbial analysis were conducted after every 15 days interval for a storage period of three months. The effect of storage time and packaging material was found to be significant on cold extrudates quality parameters and indicated that pasta is acceptable upto two months without any preservative under ambient conditions.ThesisItem Open Access DEVELOPMENT OF NUTRITIONALLY ENRICHED GLUTEN FREE PASTA USING QUALITY PROTEIN MAIZE (QPM)(UNIVERSITY OF AGRICULTURAL SCIENCES, BANGALORE, 2020-11-26) KAMBALIMATHA, VEENA. U.; KAMBALIMATHA, VEENA. U.; SHOBHA, D.; SHOBHA, D.There is an increased demand of gluten free products due to an increase in the incidence of allergies and intolerances. Study was conducted on development of nutritionally enriched gluten free pasta using Quality Protein Maize (QPM). Gluten free pasta was developed using QPM (Q), black gram flour (B) soya flour (S), spirulina (Sp) and guar gum (G) in different proportions by taking whole wheat flour (100%) as control.The different ratios of QPM and spirulina incorporated pasta were evaluated by subjective and objective methods. The best accepted ratio of QPM and spirulina incorporated pasta along with control were evaluated by assessment of characteristics such as cooking quality, physico-chemical properties, nutritional quality, storage stability, micro structural and consumer acceptability studies. Among the various blends studied, Q2 (60Q:30B:8S:2G) and S3 (60Q:30B:2S:6Sp:2G) had better acceptance as compared to other combinations tested. Incorporation of spirulina powder improved the cooking and physical parameters as compared to QPM and control pasta. Spirulina pasta was found to be nutritionally superior compared to control pasta due to increased nutrient content- protein (53 %), calcium (35 %), iron (46 %), zinc (17 %) and carotenoid contents (94 %). Incorporation of spirulina powder has lead to the improvement in microstructure of spirulina pasta as compared to QPM and control. Thus, study demonstrated that acceptable nutritionally enriched gluten free pasta suitable for all age group of people who are allergic to gluten can be prepared by combination of QPM, pulses and spirulina. Even the product provides dietary diversity to normal consumers.ThesisItem Open Access NUTRITIONAL EVALUATION OF AMLA (Phyllanthus emblica) POMACE AND ITS VALUE ADDED PRODUCTS(University of Agricultural Sciences GKVK, Bangalore, 2021-12-11) RAJU, C. A.; SHAMSHAD BEGUM, S.Amla (Phyllanthus emblica) commonly known as Indian Gooseberry, belongs to Euphorbiaceae family is known for its cool, refreshing, pleasant taste and utilised for various products and beverages. During processing, massive amounts of amla pomace that is an abundant source of polyphenols, ascorbic acid, dietary fibre and tannins is discarded as waste. Hence, the present study was undertaken to standardize the process of dehydration, analyse the nutrients and to develop value added products from dehydrated amla pomace powder. The physico-functional properties i.e., pH 3.44, colour L* 86.47, a* -0.74 and b* 11.13, particle density 1.23 g/cm3, water holding capacity 12.30 g/g, water binding capacity 12.37 g/g and swelling capacity 13 mL/g. The nutrient composition was found to have good amount of total dietary fibre (41.7g) and minerals like calcium (128mg), phosphorus (116mg) and magnesium (48mg) along with low fat (0.18g), low carbohydrate (7g) and low calorific value (36 Kcal) per 100g. The phytonutrients, viz., ascorbic acid, tannins and polyphenols were 432, 524 and 677 mg per 100g, respectively. Chikki and chutney powder with amla pomace powder at 6% and 10% substitutional levels had higher sensory scores and improved the nutritional quality. The microbial counts were within the permissible limits during 45 days of storage period. The consumer acceptance was found to be acceptable. The cost of production of Chikki and chutney powder was lower since the raw material cost was nil. Hence, amla pomace powder, a nutritious by-product can be utilized effectively as a functional ingredient in value added products.ThesisItem Open Access STUDY THE INFLUENCE OF NEW AZADIRACTIN PRODUCTS ON SEED STORABILITY OF COWPEA [Vigna unguiculata (L.)

CALYCES AND FORMULATION OF FUNCTIONAL FERMENTED BEVERAGES(University of Agricultural Sciences, Bangalore, 2022-12-19) LAIKHURAM, SARDA DEVI; VIJAYALXMI, K GRoselle (Hibiscus sabdariffa L.) calyces is an underutilized crop with potent source of bioactive components having antioxidant and antimicrobial properties. Therefore, a study was undertaken to utilize roselle calyces to formulate into functional fermented beverages. Tray drying of calyces at 50°C was standardized through colour and total antioxidant activity. Fresh and dried roselle calyces had pH, titrable acidity, TSS and brix:acid ratio as 1.06, 2.54 %, 0.63°Bx, 2.46 and 1.92, 4.13%, 3.60°Bx and 0.87 respectively. Drying reduced the moisture content from 84 to 11.08 percent. There was an increase in crude protein (7.87 %), ash (5.27 %), total energy content (316 Kcal/100g), total sugar content (54.23%), ascorbic content 15.00mg/100g, total polyphenol 562.89mg and flavanoid content 841.87mg respectively. The anthocyanin compound, Delphinidin-3- sambubioside was predominant in both fresh (13.03mg/g) and dried (39.62mg/g) calyces. Dried calyces exhibited higher antibacterial (2.57mm) and antifungal (98.66%) activities. Fermentation conditions were standardized for honey (5%), sugar (15%) and inoculum concentration, (8%) for yeast and (10%) for Lactobacillus strains. The dried calyces were inoculated with two yeast strains (Saccharomyces ellipsoideus and S. boulardii) and two Lactobacillus strains (Lactobacillus plantarum and L. acidophilus) and fermentation was done for 12 days with 7days interval. The yeast inoculated samples RET and RBT showed a highest total viable population of 7.35 and 2.81 CFU/mL respectively. Fermented beverages with yeast strains showed better microbial populations as well as sensorial characteristics compared to Lactobacillus strains. Thus, exploitation of roselle calyces as a beneficial substrate for microorganisms could be a substitute to dairy based products.
