Evaluation the tilapia meat freshness during storage in ice and refrigerator by Quality Index Method (QIM)

In this study, measurement of freshness fish tilapia species) Nile Tilapia (Oreochromis niloticus) by Quality Index method in whole fish in the 4 treatments and fillets in 6 treatments intended purpose of this research is to measure the qualitative factors (sensory , chemical and microbiological evaluation) and the ratio of 3 to 1 (Ice- fish) ice cover was (mean temperature in fish during the study period between 0.1±0.05 to 0.2±0.1 °C) were kept at cool temperatures for 10 days for the measure fillet Recently, 100 fish (50 pieces, 50 pieces of black and red) and washed her head and tail, the skin and the fillet 30 for each treatment in each treatment 3 Normal packing, vacuum and modified atmosphere (Tilapia fillets treated for red and black tilapia fillets 3 treatment) with an average weight of 114.5±22.50 grams packed and refrigerated at 3°C was maintained. The results showed maximum retention time for fish stomachs empty and whole fish respectively was 9 and 7 days. Also for tilapia fillet freshness in 3 different packaging and stored at -3°C, showed fillet packaged in MAP, has the most lasting, and results by the analysis Statistical was significant

Study the added value and acceptance of fish patty produced by FPC of Abramis brama

Abrams brama distribution in the Caspian and most of it is in the Anzali lagon. Completed in the rivers to spawn or hibernate done, hibernation mass takes place in the well of the rivers, which feed the crustaceans, mollusks and aquatic insects are born. This fish is almost vertical and is able to search for food in the mud in shallow waters and residents due to competition for food with other species of plankton and plants inevitably feed. This fish has an economic value and good taste for meat consumption has become common. Fish patty prepared food that is easy to cook and good demand. The benefits of fish patty are the most of fresh fish, good use of raw materials, availability of several species of fish in the product, socio-economic benefits for fishermen and fishing industry, product nutritional value and high in protein rejection. Fish Protein Concentrate is a healthy food products, durable and of high nutritional value of fish and hygienic manner in which the protein and other nutrients found in fresh fish and more compact than the long-term maintenance and diverse the second is for the production of food products. The study aimed at producing FPC type A string of fish, fish cakes prepared by the FPC obtained and reviewed the nutritional value, acceptance and endurance cookies generated at room temperature for one month . After examination of the nutritional value, shelf-life tests using factors of corruption, TVB-N, pH, TBArs and sensory tests showed that the most important indicator of the value of food, especially protein product treatments with better FPC and the factors corruption is not much difference between 5% FPC and blank treatment. The final product is important in terms of nutritional value and shelf life, group 2 has a significant difference with other treatments and the final product can be made on the basis of treatment 2
