【摘要】 太阳光的照射能引起桃汁贮藏过程中褐变的发生。当阳光的光照强度累计值达到９０—９９万ｌｕｘ·ｈ时，桃汁褐变的发生率可能为７０％左右。在整个反应过程中，光可能起“催化剂”的作用。更多还原

【Abstract】 he sunlight rays can cause browning during the storage of peach juice. When the accumulative value of sunlight rays intensity reaches upto 0. 9-0. 99 mition Lux·h, the browning of peach juice could be to the extent of about 70%. The sunlight may act as a "catalyzer" during the entire reaction course.更多还原
