Optimized proportion of chitosan complex biological fresh-keeping agents for the preservation of Trichiurus haumela under the cold storage
摘要
Abstract
On the base of the research of single biological fresh-keeping agent, the orthogonal experiment was made to investigate the fresh-keeping effects of complex biological fresh-keeping agents ( a mixture of chitosan, lysozyme and tea polyphenol) in the preservation of Trichiurus haumela under the cold storage ( 4 ± 1 ℃ ). The sensory scores, total volatile basic nitrogen (TVB-N), total bacterial count, 2-thioharhituric acid (TBA) and pH values were used to evaluate its quality. According to the results of orthogonal experiment L9 (33 ), the order influenced was: chitosan > lysozyme > tea polypbenol, and the optimum composition of chitosan 10.0 g · L-1 , lysozyme 0.3 g · L-1 and tea polyphenol 3.0 g · L-1 was determined. It showed that total bacterial count, TVB-N, TBA and pH value of T. haumela processed by complex biological fresh-keeping agents were much lower than those of the controlled, and had the higher sensory evaluation values. The shelf-life of T. haumela treated by the complex biological fresh-keeping agents could be extended 11 - 13 days. The cost of processing one kilogram T. haumela was only 0.24 yuan, which have great application prospects.关键词
