甘薯在贮藏期间细胞壁降解酶活性的变化
Study on the Activity of Cell Wall Degradation Enzyme of Sweet Potato in Its Storage
摘要
Abstract
The study was carried out to investigate the changes of pectin and cell wall degradation enzyme of pur- ple sweet potato and yellow sweet potato during their storage for 100 days. The purpose of the research was to find the variation of sweet potato. The sweet potato with Sportak dipping treatment（1 000mg/L） were placed in storage solu- tion under 7 ℃ , using the sweet patato stored at ambient-temperature as control （ck） , to detect the physical indica- tors periodically. The results showed that Sportak dipping treatment combined with storage at 7 ℃ effectively preven- ted the rapid decrease of content of protopectin and slowed down the increase of activity of polygalacturonase and cel- lulose. The Sportak dipping treatment combined with storage at 7 ℃ could keep higher content of protopectin and im- prove the storage quality of sweet potatoin in the actual production.关键词
