Abstract
The trial used Nanguo Pear as material,and studied the extent distributing and dynamic changing of major browning factor in the fruit during postharvest afterripening and storage. The result showed phenolic substance content and PPO activity distribute in the core were the most,that in the peel were the second,and that in the flesh were the least. The content of phenolic substance in Nanguo Pear went up during prophase of storage,and began to decrease after achieving the peak value. So was the PPO activity. The time of PPO activity reaching the peak value was the period when fruit began to appear browning,and the period when phenolic substance decreased in the gross. Browning degree had homologous relation to PPO activity and phenolic substance content.
