A Review on Utilizations of Okra Extracts for Food, Medicine and Environmental Protection
-
摘要: 近年来,黄秋葵产业在我国发展迅速,其富含黄酮、果胶等营养成分,具有降血糖、通便等生理功效。通过热水、酸碱水溶液以及醇等溶剂对黄秋葵进行提取所得的黄秋葵提取物,是一种天然、无毒和价格低廉的食品药品材料。本文介绍了黄秋葵提取物在食品、医药和环保方面的技术开发和利用研究概况,主要包括用于开发淀粉稳定剂、乳化剂、合成纳米抗菌粒子、制备药物缓释片、作为片剂包衣材料以及工业废水的处理剂等,进而综合分析黄秋葵提取物利用存在的问题并提出应对措施。Abstract: Okra (Abelmoschus esculentus) is rich in nutritive compositions, such as flavones and pectin. It is considered a functional ingredient that can reduce serum sugar and facilitate bowel movement for humans. Extracts of okra obtained by using hot water, acid or alkaline solution, or alcohol are natural, non-toxic and inexpensive for food, medicinal and environmental protection applications. Thus, the industry is developing rapidly in China in recent years. This article summarizes the current status on the processing technology and utilizations of the extracts as starch stabilizer, emulsifier, anti-bacteria nanoparticle, controlled drug release coating, and waste water treatment agent are presented. Proposals for future developments and strategies to overcome existing barriers concerning the extraction and utilization are discussed.
