The following chemical changes were observed during the cold storage of mussels for 6 days at 4 ◦C. Total volatile basic nitrogen (TVB-N, mg N per 100 g) and trimethylamine values (TMA-N, mg N per 100 g) were increased from 22.55 and 5.96 mg per 100 g at day 0 to 12.38 and 0.42 mg per 100 g, respectively, at the end of the storage period. The indole value and putrescine concentration were incre...

The effect of vacuum packing on the shelf-life of sausages produced from Capoeta umbla were investigated during storage periods. For this purpose, microbial, chemical and sensory changes were analyzed throughout the storage time. The microbial flora of the sausages comprised mainly mesophilic bacteria, psychrotrophic bacteria, lactic acid bacteria, yeast and molds. Escherichia coli, Staphylcocc...

The quality and nutritional value for both fish protein concentrate (FPC) made from tilapia by-products as well as salt-biscuits supplemented with 5% FPC were evaluated. The resultant product (FPC) was composed (on wet weight) of 4.18% moisture, 68.83% protein content, 0.75% lipid and 25.39% ash and it was more uniform in color and texture. In addition, the pH value was 6.67 and total volatile ...

The aim of this study was to investigate changes in the microbiological and physiochemical characteristics in Egyptian salted-fermented fish (Feseikh) during processing, ripening and storage. Isolation of total viable bacteria, Enterobacteriaceae, lipolytic bacteria, proteolytic bacteria, total spore forming bacteria (CFU/g) and Clostridium perfringens (MPN) from fish flesh, fish intestine and ...

The present work was carried out to study the effect of vacuum packaging and pomegranate peel extract (PE) treatments on the quality of pacific white shrimp (Peneous vannamei) during refrigerated storage. Changes in pH, thiobarbituric acid (TBA), total volatile base nitrogen (TVB-N), trimethylamine (TMA), aerobic plate counts, psychrophilic, lactic acid bacteria and enterobacteriaceae counts, m...

effects of catechin for preventing black spots forming in whiteleg shrimp (litopenaeus vannamei) were evaluated. for processing whole shrimp, catechin was used at a concentration of 0.2 and 0.3 % for 15 minutes. sodium metabisulfite was used at a concentration of 3 % for 10 minutes as control samples. without antioxidant shrimp were used as control samples too. treatments quality was evaluated ...

The quality of minced kilka (Clupeonella cultriventris caspia) with gum arabic encapsulated (0.3% and 0.5% w/w) and unencapsulated fennel extract (FE) (0.3% and 0.5% w/w) stored at 4°C was examined over a storage period of 15 days. The control and the treated fish samples were analyzed periodically for microbiological (total viable count [TVC] and total psychrotrophic count [TPC]) and chemical ...

The fresh mackerel was frozen using four different quick-freezing methods, such as refrigerator freezing, quick freezer spiral tunnel freezing and plate freezing. Water retention, color, texture, electrical conductivity, total volatile base nitrogen (TVB-N), K value, malondialdehyde (MDA), sulfhydryl group protein secondary structure were used physicochemical indicators to evaluate the changes ...
