摘要
大豆分离蛋白(SPI)膜作为可食性包装材料具有独特的优异性,但是成膜后的稳定性还有待解决.主要研究了SPI膜在储藏期间水分及机械性能的变化,研究结果表明,储藏环境的相对湿度、储藏方式(常温、冷藏、冻藏)、甘油添加量都会影响膜的水分及机械性能,SPI膜在储藏期间变化的水分主要是中间水,水分的变化是影响机械性能变化的一个主要因素.
As edible packaging materials,soy protein isolate（SPI） films have its own unique superiority,but the problem to be solved is the film stability. This research mainly studied the changes on moisture content and mechanical properties of the SIP films during storage. Results showed that relative humidity（ RH）,storage mode（room temperature,chilled,frozen）,and glycerol addition amount affected the moisture content and mechanical properties of SPI films. During storage,the moisture changed in the SPI films during storage is mainly the intermediate water. In addition,change on moisture content is the major factor affecting the mechanical properties.
