摘要:

以聚乙烯醇为基膜材料,分别加入2 g/100 mL壳聚糖季铵盐、0.5 g/100 mL茶多酚、2.5 g/100 mL丙酸钙、0.5 g/100 mL对羟基苯甲酸乙酯联合1.5 g/100 mL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、pH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 mL茶多酚和添加0.5 g/100 mL对羟基苯甲酸乙酯联合1.5 g/100 mL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。

Abstract:

The preservative effect of antibacterial polyvinyl alcohol packaging films, fabricated with polyvinyl alcohol and one
of four antioxidant treatments (2 g/100 mL chitosan quaternary ammonium salt, 0.5 g/100 mL tea polyphenols, 2.5 g/100 mL
calcium propionate, 0.5 g/100 mL, or ethylparaben + 1.5 g/100 mL calcium propionate) on bream meat was examined
by measuring water-holding capacity (WHC), pH, 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 mL tea polyphenols and 0.5 g/100 mL ethylparaben +
1.5 g/100 mL calcium propionate could keep the bream fresh effectively during (4 ± 1) ℃ storage.
