Abstract: By using the postharvest Huping jujube and pear jujube as test materials, and studying the browning degree and reactive oxygen metabolism of jujube peel, this article explores the relationship between active oxygen metabolism and browning of postharvest jujube peel. The result shows: the browning degree of the postharvest jujube peel increased significantly, the SOD, CAT activities and the VC content of endogenous antioxidants of the reactive oxygen scavenging enzymes in the peel showed a descending trend, while the production efficiency of O-2, content of H2O2 and the relative conductivity ratio showed an ascending trend. A significant negative correlation was found between SOD activities and O-2 production efficiency, as well as between CAT activities and H2O2 content; this showed that during the redden process of the postharvest jujube, there was an accumulation of reactive oxygen due to a drop in the scavenging ability of antioxidant enzymes and compounds, as well as a strengthening of
Jujube peel’s lipid peroxidation evidenced by the increases in the relative conductivity ratio and MDA content. Summing up the above, it is found that during the redden process of postharvest jujube, the causes of browning were due to reactive oxygen metabolic disorder and the enhancement of lipid peroxidation.

Abstract; this paper in order to harvest dates and Lizao pot bottles as materials, peel browning by date, reactive oxygen metabolism studies to explore the fruit harvest dates of active oxygen metabolism in relation to their browning. The results showed that: jujube fruit harvest significantly increased degree of browning, peel active oxygen scavenging enzymes SOD, CAT activity and endogenous antioxidant content of the VC were decreased, while the O-2 formation rate, H2O2 content and relative conductivity were on the rise; peel SOD activity and O-2 formation rate, CAT activity and H2O2 content showed a significant negative correlation, indicating that post-harvest to red jujube in the process of antioxidant enzymes and antioxidants for scavenging reactive oxygen species ability decreased, leading to the accumulation of reactive oxygen species; turn red jujube harvest process, the relative conductivity increase, MDA content increased, showing that jujube fruit enhanced membrane lipid peroxidation. To sum up the process of post-harvest jujube-red mesocarp of reactive oxygen species metabolic disorders, to enhance membrane lipid peroxidation, leading to the occurrence of browning....

The; This paper to postharvest pot dates and a bottle LiZao as test materials, through to the date peel Browning degrees, active oxygen metabolism research, exploration of postharvest jujube peel active oxygen metabolism and Browning relationship. The results show that: postharvest date fruit peel Browning degrees, a significant increase the enzyme SOD, CAT active oxygen removal activity and endogenous antioxidants VC the content are declined, and O, 2 formation rate, H2O2 content and electric conductivity are relatively rise; Peel SOD activity and O, 2 formation rate, CAT activity and H2O2 content are significant negative correlation postharvest jujubes, show that in turn red fruit in the process of antioxidant enzymes and antioxidant ability of active oxygen removal of epicuticular reduced, cause reactive oxygen species accumulation; Postharvest date fruit turn red process, the relative electrical conductivity increases, MDA content increases, visible date fruit peel membrane lipid peroxidation strengthen. In postharvest date fruit that turn red process ZhongGuoPi active oxygen metabolism disorders, membrane lipid peroxidation, lead to strengthen the occurrence of Browning.
