大豆蛋白薄膜改性技术研究进展

Research Progress on Modification Technology of Soy Protein Film

大豆蛋白膜因其无污染、可生物降解、来源广泛及透气性低等优点,成为当前的研究重点。但其抗拉强度低、延伸率较差且易导致细菌滋生,致使其应用受到严重影响。因此需要对大豆蛋白薄膜进行改性,以适应不同的用途。本文介绍了用于提高大豆蛋白使用性能的薄膜物理改性、纳米材料改性、化学改性、混合改性、酶法改性等改性方法,总结目前大豆蛋白薄膜的主要应用领域和需要解决的问题,并展望其发展方向。

Soy protein film has become the current research focus due to its non-polluting, biodegradable and low air permeability advantages. But its low tensile strength, poor elongation and prone bacterial growth cause its application has been severely compromised. Therefore, it is necessary to modify the film of soy protein. This article introduced the physical modification, nanomaterial modification, core modification, hybrid modification and enzymatic modification of soybean protein film to improve its performance. We also summarized the main application fields of soy protein films, the existing problems, and look forward to its development direction.
