摘　　要：大豆蛋白材料的改性方法主要有物理改性、化学改性、酶法改性以及纳米共混改性等。对大豆蛋白材料的性能改善研究主要集中于薄膜材料的成膜性能、机械性能、吸水性能、透光性能、阻气性能和水蒸气透过性能、生物降解性能等方面。大豆蛋白基生物降解材料多被用作制备可食性薄膜,应用于果蔬的涂抹保鲜及部分食品的内包装;改性后的大豆蛋白可作为营养保健物质用作生物材料及生物医用材料。大豆蛋白基生物降解材料未来的发展方向主要为降低成本及增强性能等研究。The main modified methods of soy protein materials include physical modification, chemical modification, enzymic modification, nanocomposites modification. And the performance of soy protein materials study is mainly focused on improving their film-forming properties, mechanical properties, water absorption ability, light transmittance, gas barrier properties and water vapor permeability, biodegradability, etc. Soy protein-based biodegradable materials are usually used in the edible film, the preparation of fresh fruits and vegetables and the inner packaging of some food. Besides, the modified soy protein can be used as nutritional substances as bio-materials and bio-medical materials. The research of how to reduce costs and enhance performance will be the main future development direction of soy protein-based biodegradable materials.
