摘要
本文分析了钙处理及热加钙处理对桃冷藏期间H_2O_2含量以及其清除系统中的重要物质GSH(谷胱甘肽)、抗坏血酸含量和GR(谷胱甘肽还原酶)活性的影响,结果表明:钙处理降低了桃中H_2O_2的积累,对抗坏血酸含量变化无影响,延迟了GSH含量的积累,增加了GR活性,热加钙处理降低了桃中H_2O_2的含量,提高了抗坏血酸的含量,推迟了GSH含量高峰出现的时间。
The effects of Ca ̄(++)reatment and heat treatmet complemented with Ca ̄(++) on H2O2,ascorbic acid and GSH content as well as GR asctivity of peach stored at low temperature werestudied in this article.Ca ̄(++)treatment decreased the accumulation of H_2O_2 content,had no effecton the ascorbic acid content,delayed the accumulation of glutfqthione content,and increased thepeak of GR activity. Heat treatment complemented with Ca ̄(++) decreased the accumulation ofH_2O_2content and the peak of GR activity,but increased the assorbic acid content and postponedthe rise of GSH content peak.
