Abstract/OtherAbstract:
BACKGROUND: The spoilage of fishery food has been attributed to limited types of microorganisms called specific spoilage organisms (SSO). Unlike traditional food-preserving techniques which usually exploit broad-spectrum antimicrobial agents, here, based on the specific antimicrobial activity of egg yolk antibodies (IgY) against two SSO in refrigerated fish (Shewanella putrefaciens and Pseudomonas fluorescens), a novel strategy for fish preservation was suggested and evaluated. RESULTS: During storage of Paralichthys olivaceus fillets at 4 ± 1 °C, the bacteria growth (including total microorganisms and the two SSO) in test groups was significantly inhibited in comparison to that of controls (P < 0.05). This antibacterial activity of the specific IgY was also confirmed by chemical analysis (pH, total volatile base nitrogen and 2-thiobarbituric acid value) and sensory evaluation, and the shelf life of samples was extended approximately from 9 days to 12-15 days in the presence of the specific IgY. CONCLUSION: These results indicated a significant antimicrobial activity of the anti-SSO IgY for refrigerated fish products, which allowed us to suggest its potential as a bio-preservative for seafood.
