紫甘薯及其花色苷的研究与开发进展

紫甘薯含有花色苷、绿原酸、异绿原酸等功能成分，具有抗氧化、抗突变、保护肝脏、缓解高血压、高血糖、高血脂、增强记忆、抗菌等生理功能。目前国内外已针对紫甘薯开发出一系列食品及食品工业原料，其生产及应用受到越来越多的关注，是一种很有发展前景的经济作物。本文主要针对紫甘薯及其花色苷的理化性质、生理功能、开发应用及其发展前景加以概述，以期为紫甘薯资源合理开发利用提供参考。

Research Progress on Purple Sweet Potato and Its Anthocyanins

Purple sweet potato (PSP) contains a variety of functional components, such as anthocyanins, chlorogenic acid and isochlorogenic acid. Therefore, PSP is endowed with multiple physiological functions including antioxidation, antimutation, hepato-protection, antihypertension, antihyperglycemia, antihyperlipidemia, memory enhancing, and antibacterial activities. Varied foods and food materials have been developed from PSP both at home and abroad. Therefore, PSP can be recommended as a superior cash crop for the production of foods of health benefits. In order to provide theoretical basis for better exploration of PSP resources, the research progress on physicochemical property, physiological functions, development and application of PSP and its anthocyanins in recent years is summarized in this paper.
