摘　　要：目的研究异硫氰酸烯丙酯在冷鲜肉保鲜中的应用。方法在贮藏期间,利用异硫氰酸烯丙酯挥发性来处理冷鲜肉。冷鲜肉经过异硫氰酸烯丙酯及其微胶囊处理后,测量其5项理化指标(pH值、失水率、挥发性盐基氮值、硫代巴比妥酸值及菌落总数)来检测冷鲜肉在贮藏过程中的变化。结果使用异硫氰酸烯丙酯处理后的冷鲜肉的货架期较空白对照组和不含异硫氰酸烯丙酯微胶囊处理组相比时间更长,可以将冷鲜肉的货架期延长至10 d。结论异硫氰酸烯丙酯可以延长冷鲜肉货架期。Objective To study the application of allyl isothiocyanate in pork preservation.Methods During the preservation process,cold fresh meat was treated with allyl isothiocyanate volatility.After the chilled fresh pork was treated with allyl isothiocyanate and its microcapsule,5 physical and chemical indexes(pH value,water loss rate,volatile base nitrogen value,thiobarbituric acid value and total number of colonies)were measured to detect the changes of chilled fresh pork during storage.Results The shelf life of the cold fresh meat treated with allyl cyanate was longer than that of the blank control group and the microencapsulated group without allyl isothiocyanate,which could extend the shelf life of the cold fresh meat to 10 d.Conclusion Allyl isothiocyanate can extend the shelf life of chilled fresh meat.
