摘  要:
以木薯淀粉、壳聚糖为原料,研制可食性复合保鲜膜,并测试其性能,同时将其应用于羊肉保鲜中.结果表明:当2%木薯淀粉溶液与2%壳聚糖溶液的配比为1.5:1时得到的复合膜综合性能最优,其拉伸强度、断裂伸长率、透水气率和透光率分别为(47.75±2.49)MPa、(77.4±2.3)%、(0.355±0.056)g·mm/(h·rn.kPa)、(70.4±1.02)%.该复合膜包装冷藏羊肉(4℃),在贮藏期10d内,羊肉失水率、挥发性盐基总氮值、丙二醛值均低于未包复合膜的羊肉,并且差异显著(P〈O.05).

摘  要:
Abstract: The preparation of edible composite film of cassava starch and chitosan was studied, and the properties of the edible composite film were tested. Besides, its application to preserve mutton was observed. The results showed that edible composite films formed from 2% cassava starch and 2% chitosan at a ratio of 1.5:1 had the best overall performance; the tensile strength, bibulous rate, elongation at break, water vapor permeability and transmittance were (47.75 ± 2.49) MPa, (77.4 ± 2.3), (0.355 ± 0.056) g'mm/(h'm2"kPa) and (70.4 ± 1.02)%, respectively. Within 10 days of storage at 4℃, water loss rate, total volatile basic nitrogen (TVB-N) and TBA were significantly lower in mutton packaged with this edible film than control mutton (P〈0.05).
