Abstract
Browning occured very easily during the procession of dried apple slice.In this study,the characteristics of polyphenol oxidase in apple were investigated.By an orthogonal experiment of L9( 34) ,a kind of mixed soaking solution which was safe and effective for color protection was obtained.The results showed that polyphenol oxidase in apple was actively at pH6.0 and 36℃,and the activity was almost lost in condition of 100℃,60s.After the apple were soaked in the mixed solution which consisted of 0.6% citric acid,0.06% L-cys and 1.5% NaCl,and dried at 50℃,0.09MPa,the color of the dried apple slice was good.
