摘要
以聚乙烯醇为基膜材料,分别加入2 g/100 m L壳聚糖季铵盐、0.5 g/100 m L茶多酚、2.5 g/100 m L丙酸钙、0.5 g/100 m L对羟基苯甲酸乙酯联合1.5 g/100 m L丙酸钙做为抗菌剂,制得的聚乙烯醇抗菌包装薄膜,在冷藏(4±1)℃条件下对鳊鱼肉进行包装保鲜。以持水率、p H值、白度、硫代巴比妥酸值、挥发性盐基氮值、菌落总数、质构指标、感官评定对保鲜效果进行评价。结果表明:添加0.5 g/100 m L茶多酚和添加0.5 g/100 m L对羟基苯甲酸乙酯联合1.5 g/100 m L丙酸钙的聚乙烯醇抗菌保鲜薄膜对(4±1)℃鳊鱼具有最佳的保鲜效果。
The preservative effect of antibacterial polyvinyl alcohol packaging films, fabricated with polyvinyl alcohol and one of four antioxidant treatments(2 g/100 m L chitosan quaternary ammonium salt, 0.5 g/100 m L tea polyphenols, 2.5 g/100 m L calcium propionate, 0.5 g/100 m L, or ethylparaben + 1.5 g/100 m L calcium propionate) on bream meat was examined by measuring water-holding capacity(WHC), p H, whiteness, thiobarbituric acid(TBA), total volatile basic nitrogen(TVB-N), aerobic plate count, texture properties and sensory evaluation during storage at(4 ± 1) ℃. The results indicated the antibacterial polyvinyl alcohol packaging films with 0.5 g/100 m L tea polyphenols and 0.5 g/100 m L ethylparaben + 1.5 g/100 m L calcium propionate could keep the bream fresh effectively during(4 ± 1) ℃ storage.
