摘要:

采用茶多酚、大蒜素与天然可食性膜溶液研制成涂膜保鲜剂进行冷却肉的涂膜保鲜研究。以感官指标、pH 值、挥发性盐基氮(TVB-N)和细菌总数为考察指标,通过L9(34)正交试验筛选出最佳比例组合,提高冷却肉的保鲜度和延长冷却肉的保鲜期。结果表明:0.7% 茶多酚、0.4% 大蒜素和乙种膜溶液(3% 可溶性淀粉、0.6% 海藻酸钠、0.2% 单甘酯)组成的涂膜保鲜剂,对冷却肉的涂膜保鲜效果良好。用此涂膜保鲜剂处理冷却猪肉,在0~4℃条件下贮藏保鲜19d 以上。

Abstract:

Tea polyphenol and allicin were added to edible film-forming solutions to prepare a novel coating for the coating preservation of chilled pork. To increase the freshness and shelf life of chilled pork, a L9(34) orthogonal array design was used to investigate the effect of coating formulation on pH value, TVB-N value, total bacterial number and sensory quality of chilled pork. The results showed that the optimal coating formula consisted of tea polyphenol 0.7%, allicin 0.4% and an edible filmforming solution consisting of soluble starch 3%, sodium alginate 0.6% and monoglyceride 0.2%. No significant sensory and physico-chemical changes were observed in chilled pork treated with the coating formula after 19 days of storage at 0—4 ℃.

Key words: chilled pork, tea polyphenol, allicin, coating preservation
