The results showed that heat treatment improved hardness and soluble solid content of stored pear fruit, postponed the improvement of MDA content and PPO activity in stored pear fruit and alleviated the reduction of SOD activity and the lowering of PG activity. To sum up, heat treatment reduces the occurrence of browning of stored pear fruit through the regulation of the changes in a series of physiological and biochemical indexes of fruit.展开更多

文摘The effect of postharvest heat treatment on browning of Huangguan pear was investigated. The results showed that heat treatment improved hardness and soluble solid content of stored pear fruit, postponed the improvement of MDA content and PPO activity in stored pear fruit and alleviated the reduction of SOD activity and the lowering of PG activity. To sum up, heat treatment reduces the occurrence of browning of stored pear fruit through the regulation of the changes in a series of physiological and biochemical indexes of fruit.
