title: Effect of peach gum polysaccharides on quality changes of white shrimp.
abstract: Peach gum polysaccharides (PGPs) have both antibacterial and antioxidant activities. In this study, the retardation effect of the PGPs on the quality changes of white shrimp (Penaeus vannamei) during refrigerated storage was investigated. Shrimp samples were untreated with different concentrations of the PGPs solution and then they were stored under refrigerated conditions for 10 days. During refrigerated storage, shrimp samples were taken periodically and their total viable count, pH value, total volatile basic nitrogen, and overall acceptability score were evaluated. Compared to the control, treatment of the PGPs solution effectively retarded bacterial growth and pH changes, reduced total volatile basic nitrogen, and increased overall acceptability score of white shrimp (P. vannamei) during refrigerated storage. The results indicate that treatment of PGPs could be a promising means to preserve white shrimp (P. vannamei).
