Abstract
High spoilage ability of fishes has caused preservation of fresh fish quality to be one of notable important issues in fishery industry and for consumers. In this study the effects of Nisin Z (%0.2) (treatment no.1) was considered separately and simultaneous with sodium acetate (2g/100ml) (treatment no.2) on silver carp (Hypophthalmichthys molitrix) fillets during refrigerator storage. Fish fillets were vacuum packed and stored in refrigerator at 4?C for 9 days. Microbial parameters (the total viable, psycrotrophic and lactic bacteria counts) and chemical parameters (PV, TBA, TVB-N) and so pH value (all over days), total protein, moisture and ash (in first time) were measured at days of 0, 3, 6 and 9. TVN and TBA levels in treatment no.1 and no.2 significantly (p<0.05) increased during storage period, but did not exceed to allowed limit until 9th day, while the control samples reached this limitation at 4th day. Control samples had higher Psychrotrophic bacteria, lactic and total bacteria cont which followed by samples of treatment no.1 and then treatment no.2 in the days of 4, 6 and 9 respectively. Results showed that simultaneous use of sodium acetate and Nisin Z could increases shelf-life of silver carp fillet packed in vacuum bag for 5 days at 4?C.
