大豆分离蛋白膜制备及改性研究的现状和应用

目的整理和归纳目前国内外关于大豆分离蛋白(Soy Protein Isolate,SPI)膜的制备方法及改性研究的最新研究成果,为将来制备高性能的该系列材料提供依据。方法归纳整理国内外文献,从文献中归纳SPI膜的基本性能和目前SPI膜的3种主流制备方法,并从力学性能、防潮性能、抑菌性能、阻氧阻湿性能等4个方面介绍SPI膜的改性研究现状,最后对SPI膜的应用情况进行归纳。结果 SPI具有来源广泛、价格低廉、环境友好等诸多优点。在对其进行改性后,由SPI制备薄膜的成膜性能、力学性能、防潮性能、抑菌性能、阻氧阻湿性能均有显著提高。结论对SPI膜进行有效改性后,其在保鲜包装、环保包装、可食用包装、风味食品包装等领域具有广泛且良好的发展前景。

Current Situation and Application of Preparation and Modification of Soy Protein Isolate Film

The work aims to collect and summarize the latest research results on the preparation and modification of soy protein isolate (SPI) film at home and abroad to provide basis for the preparation of high-performance series of materials in the future. The basic properties of SPI films and the three main preparation methods of SPI films were summarized by sorting out the literature at home and abroad. The current research situation of SPI modified films was introduced from four aspects, including mechanical properties, moisture-proof properties, bacteriostasis, oxygen and humidity resistance. Finally, the potential application directions of SPI films were summarized. SPI had many advantages, such as wide source, low price, environmental friendliness, etc. After modification, the film-forming properties, mechanical properties, moisture-proof properties, bacteriostasis, oxygen and humidity resistance of SPI films were significantly improved. After effective modification, SPI film has broad and good development prospects in the fields of fresh-keeping packaging, environmental protection packaging, edible packaging, flavor food packaging, etc.
