- ItemGender Roles and Livelihood Analysis of Women in Dry Fish Processing: A Study in Coastal Odisha(Society of Fisheries Technologists (India)Cochin, 2014)This study was undertaken to document the socioeconomic and livelihood profile, gender roles in fish curing, trade and marketing and perceived needs of women in dry fish processing in coastal Odisha. Majority of the respondents were middle-aged and had more than 10 years of experience in dry fish production and handling, with high social participation through self help groups (SHGs) and moderate decision making power in family and their trade. Majority of them (72.41%) were illiterates. Annually, they spend about 225-250 days in dry fish production process of low to medium valued fishes. Dry fish production was the primary occupation and secondary occupations include wage earnings in shrimp exporting units, ice production units, net mending, poultry, prawn peeling, farming, etc. Non-availability of good quality raw materials, lack of alternative drying methods during rainy season, lack of proper infrastructural facilities for drying, contamination with sand, microbes, attack of insects, birds and animals, non-availability of proper storage facilities, inadequate institutional credit facilities, exploitation by middlemen and inadequate transportation facilities were the major constraints perceived by the respondents. Most of them were not aware of the improved practices including packaging and quality assessment.
- ItemImpact of Compliance with Food Safety Measures in Fish Processing Units(Society of Fisheries Technologists (India)Cochin, 2014)Increasing consumer demand for greater food safety, particularly in developed countries has triggered the need for an integrated approach for ensuring food safety in the entire food production chain viz., from farm to fork. This study estimates the cost of compliance with food safety measures in fish processing plants. The study is based on primary data collected from 14 fish processors cum exporters in West Bengal in the year 2011. West Bengal is one of the largest seafood exporters and contributes about 9% to the total seafood export from India. The study shows that status of compliance with food safety measures in Indian fish processing plants is satisfactory. Though the cost of compliance with food safety is high, it is beneficial to processor/ exporter in better price realization and acceptance of the products in international markets. The compliance with food safety measures can be further enhanced by easy and cheap availability of credit to processors and capacity building of all stakeholders in fish supply chain for their better adoption at lower level of supply chain to ensure safe raw material for the processing industries
- ItemEffect of Binders on the Quality of Restructured Products from Silver Carp (Hypophthalmichthys molitrix) Surimi(Society of Fisheries Technologists (India)Cochin, 2014)The present study deals with the use of wheat flour and soya flour as additives in thermal gelification of surimi from silver carp muscle to obtain quality restructured products. Biochemical and mechanical properties of restructured products and changes during storage at -20oC were measured. Water holding capacity of the gel increased significantly when wheat flour and soya flour were added as binders. As regards mechanical properties, the gel strength, hardness and cohesiveness of gel with wheat flour showed intermediate value between control and gel with soya flour. But the springiness of wheat flour-added gel was superior. After 120 days of storage at -20oC, the wheat flour-added gel maintained superior quality amongst others. The study revealed that quality restructured products could be made with thermally set silver carp surimi with or without adding any binder, but wheat flourincorporated gel maintained superior quality up to a storage period of 120 days.
- ItemDevelopment of Functional Pasta Enriched with Omega-3 Fatty Acids(Society of Fisheries Technologists (India)Cochin, 2014)Omega 3 fatty acid-enriched functional pasta products were developed using refined wheat flour, water, salt, fish meat and fish oil using a single screw extruder. Among the different blends studied, the most acceptable pasta was made with combination of maida (800 g), water (240 ml), fish oil (1%), fish meat (200 g). This product had a protein content of 4.84% which is higher than the regular pasta available in the market. Fatty acid profile study showed that the developed pasta had a omega-3 fatty acid levels of 974 mg. Storage study revealed that peroxide value and free fatty value are within the acceptable limit for a period of 8 weeks. Therefore the result of the present study indicate that fish meat and fish oil can be utilized for the development of well accepted functional pasta products rich in protein and omega-3 fatty acids.
- ItemCharacterization of a Bioactive Protein with Antimicrobial Property from Loligo sp.(Society of Fisheries Technologists (India)Cochin, 2014)Loligo is a genus of squids. Due to their abundance and economic importance in the export market, squids have been studied for their biology and fishery characteristics. The aim of the current study was to investigate anti-microbial activity associated with proteins extracted from this organism. Whole body tissue was homogenized with protein extraction buffer and its antimicrobial activity was screened against Klebsiella pneumoniae, Bacillus cereus, Salmonella typhimurium, Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa and Vibrio cholerae by agar well diffusion method. The protein was concentrated by acetone precipitation. Purification was done in different steps employing cut off membrane filtration, thin layer chromatography (TLC) and Sephadex G-50 gel filtration column. The molecular weight of the protein was determined by SDS-PAGE. A 45 kDa protein was isolated and purified from Loligo with a total yield of 0.06% which showed bioactivity against V. cholerae. MALDI and MASCOT analysis showed that the 45 kDa protein had a similarity score of 40 with parvalbumin protein of Fundulus similis.
