褪黑素处理对采后冬枣贮藏期间品质的影响
Effect of melatonin treatment on quality of postharvest winter jujube during storage
摘要
Abstract
In order to explore the effect of melatonin treatment on the preservation of winter jujube after harvest,freshly harvested winter jujube in the semi-red stage was used as the experimental material,and the fruit was stored at 0 ℃[relative humidity was(90±5％)]for 60 days.The fruit was treated separately by 100,150,and 200 μmol/L melatonin,and the optimal melatonin concentration to maintain the quality of winter jujube during storage was screened out through the weight loss rate,hardness,peel browning index,poly-phenol oxidase(PPO)activity,and other indexes related to storage quality and color change.The results showed that 150 μmol/L melato-nin treatment could significantly reduce the weight loss rate and PPO activity,as well as the increase of hardness,total soluble solids(TSS),and titratable acidity(TA).It effectively inhibited the increase of chlorophyllase(Chlase)activity,enhanced the activity of fla-vonoid glycosyltransferase(UCFT),and effectively inhibited the decrease of chlorophyll and carotenoid content and flavonoid content,de-layed fruit browning,maintained the quality of winter jujube fruit,and prolonged the storage period of fruit.In conclusion,150 μmol/L melatonin treatment could effectively maintain the storage quality of winter jujube and delay the deterioration of color,which provided a theoretical basis for the application of melatonin in postharvest preservation of winter jujube.关键词
