The combined effect of nisin, sodium acetate to increase the shelf life of trout in form Completely empty stomach

Nisin is a natural antimicrobial and has inhibitory effect on the pathogens and spoilage organisms. The purpose of this study was first to evaluate the effects of nisin (0.15 %) and sodium acetate (1%) individually and in combination on shelf life of whole trout (without viscera). Physical and chemical parameters including pH, PV, TBA and TVN and bacterial factors such as TVC, PTC and LAB were examined. These parameters were done at intervals of 4 days for 16 days. Results showed that the peroxide value , the thiobarbituric acid, volatile nitrogen bases , and pH in combination of sodium acetate and nisin Z treatments were exposed to significantly compared to control treatments (no preservatives) (p<0.05). Treatments with sodium acetate and nisin Z (individual) were existing after combination treatment. It seems that a combination of natural and chemical preservatives in fish stomachs empty, salmon survival time increases significantly
