甘薯紫色素及提取技术研究进展

摘要

Purple fleshed sweet potatoes are ant hocyanin rich foods. Anthocyanin pigments of purple fleshed sweet potatoes show functions of anti oxidation and antimutagenicity , they also can prevent carbon tetrachloride induced acute liver dam age in t he rat and reduce the risk of coronary heart disease. The advantages and disadvantages of extracting methods such as organic solvent method and microwave and ultrasonic and the best technological parameter are summarized in this paper, and the results showed that microwave method are the best way according to the productivity.%紫薯色素主要含花青素类色素，它具有抗氧化、抗突变、减轻肝机能障碍与心血管疾病等作用。本文综述了紫薯色素的有机溶剂提取法、超声辅助提取法、微波提取法各自有缺点及最佳提取工艺参数以及产率的大小，综合分析认为微波提取法效果最好。
