以豆渣为基材，海藻酸钠和羧甲基纤维素为成膜剂，甘油为增塑剂，研究了成膜剂和增塑剂对膜性能的影响，并通过正交试验，优选了可食性膜的配方。结果表明，豆渣的添加量为2.0 g，羧甲基纤维素为1.4 g，海藻酸钠为1.0 g，甘油为1 mL时，可食性复合膜的综合性能良好。豆渣可食性膜的研究，既实现了废物利用，又保护了环境，具有广阔的发展前景。

Soybean residue was used as substrate, sodium alginate and carboxymethyl cellulose as film-former, glycerin as plasticizer, to prepare edible film. The influence of film-former and plasticizer on the film performance was studied. The optimum edible film formula was determined with orthogonal test. The result showed that when soybean residue is 2.0 g, carboxymethyl cellulose is 1.4 g, sodium alginate is 1.0 g, glycerin is 1mL, and the comprehensive performance of composite edible film is good. The purpose of this study was to recycle and protect environment.
