甘薯茎叶生理功能与其加工利用

甘薯是我国大宗农产品, 其茎叶常作为饲料或者直接废弃。目前研究表明, 甘薯茎叶含有丰富的营养成分, 包括糖、蛋白质、维生素、钾、钙、铁等微量元素。此外还含有黄酮类化合物、绿原酸、多糖等多种生理活性成分, 具有多种医疗保健功能, 如防癌、降血糖、降血脂、抑菌防腐等功效。因此, 对甘薯茎叶资源进行开发和利用, 不但可以提高农业附加值, 还能为消费者提供健康食品。本文详细论述了甘薯茎叶的活性成分及其生理功能, 并简要介绍了甘薯茎叶的加工现状, 提出未来研究和发展趋势, 为更好利用甘薯资源提供参考。

Advances on physiological activities and processing utilization of sweet potato stems and leaves

Sweet potato is a large-scale agricultural product in China, and its stems and leaves are often used as feed or directly discarded. Current research shows that sweet potato stems and leaves are rich in nutrients, including trace elements such as sugar, protein, vitamins, potassium, calcium and iron. In addition, it also contains various physiological active ingredients such as flavonoids, chlorogenic acid and polysaccharides, and has various health care functions, such as anti-cancer, blood sugar lowering, blood fat reduction, antibacterial and antiseptic effects. Therefore, the development and utilization of sweet potato stem and leaf resources can not only improve the added value of agriculture, but also provide consumers with healthy food. This paper detailedly discussed the active constituents and physiological functions of sweet potato stems and leaves, briefly introduced the processing status of sweet potato stems and leaves and proposed future research and development trends, so as to provide reference for better utilization of sweet potato resources.
