Recently, there is an increasing interest of using bio-based polymers instead of conventional petroleum-based polymers to fabricate biodegradable materials. Soy protein isolate (SPI), a protein with reproducible resource, good biocompatibility, biodegradability, and processability, has a significant potential in the food industry, agriculture, bioscience, and biotechnology. Up to now, several technologies have been applied to prepare SPI-based materials with equivalent or superior physical and mechanical properties compared with petroleum-based materials. The aim of this review is focused on discussion of the advantages and limitations of native SPI as well as the bulk and surface modification strategies for SPI. Moreover, some applications of SPI-based materials, especially for food preservation and packaging technology, were discussed.
最近，人们越来越感兴趣地使用生物基聚合物代替传统的石油基聚合物来制造可生物降解材料。大豆分离蛋白 (SPI) 是一种具有可再生资源、良好的生物相容性、可生物降解性和可加工性的蛋白质，在食品工业、农业、生物科学和生物技术方面具有巨大的潜力。到目前为止，已经应用了几种技术来制备具有与石油基材料相当或更优的物理和机械性能的 SPI 基材料。本综述的目的是集中讨论天然 SPI 的优点和局限性以及 SPI 的本体和表面改性策略。此外，还讨论了 SPI 基材料的一些应用，特别是在食品保鲜和包装技术方面的应用。
