可食性包装膜是近年来包装材料的研究热点。一般可食性包装膜是以多糖、纤维素和蛋白质等作为主要基本材料,复合以酯类等有机物材料,形成具有较好的机械加工性能的可食性包装膜。蛋白质作为可食性包装膜的基本材料具有诸多优点,然而以往的蛋白质提取一般局限于植物材 Edible packaging film is the research focus of packaging materials in recent years. General edible packaging film is based on polysaccharides, cellulose and protein as the main basic material, combined with esters and other organic materials, forming a good mechanical processing properties of edible packaging film. Protein has many advantages as a basic material for edible packaging films, however, conventional protein extraction is generally limited to plant material
