摘要: 研究以大豆皮果胶为基质,添加壳聚糖、聚乙烯醇、甘油后形成的果蔬保鲜复合膜,并分析复合膜的感官性质、膜厚度、透湿性、抑菌性以及红外光谱。通过均匀试验设计,结果表明:由质量分数0.2%果胶、0.6%壳聚糖、0.3%聚乙烯醇、0.3%甘油混合制得的涂膜液具有较好的应用前景。

Abstract: The objective of the present study was the development of a compound film-coating fresh-keeping agent for fruits and vegetables using soy hull pectin as base material with added chitosan, polyvinyl alcohol and glycerin. The formulation of the four components was optimized by uniform design based on sensory evaluation, film thickness, moisture permeability, antimicrobial activity and infrared spectral analysis. The results showed that the optimal film formula consisted of 0.2% pectin, 0.6% chitosan, 0.3% polyvinyl alcohol and 0.3% glycerin.

Key words: soy hull, pectin, edible film
