| 摘 要： | 应用分光光度法测定苹果及果汁中原花青素含量重现性高,快速、准确、操作简便,可用于果汁加工及以原花青素为功能因子的保健品生产的质量控制.果汁加工过程中原花青素含量的变化对苹果汁色泽、澄清度及贮藏稳定性影响很大,其中原花青素的氧化聚合是造成果汁品质下降的主要原因.因此,可通过果汁加工前除去原花青素及防止原花青素氧化等措施提高苹果汁的质量.

| Abstract: | A spectrophotometric method was developed for determination of total proanthocyandins in apple This method was simple,accurate and rapid,which could be used to examine the quality during the processing of apple juice and health food contained proanthocyandins The variation of the content of proanthocyandins during apple juice processing had great effect on the color,clarification and stability of apple juice Oxidization of proanthocyandins was the main reason that decreased the quality of apple juice and the content of total proanthocyandins So,in order to improve the quality of apple juice,the measure of removing proanthocyandins before juice processing or preventing from oxidization of proanthocyandins during processing should be taken |
