不同采收期对'龙眼'葡萄贮藏保鲜效果的影响
Effect of Different Harvest Periods on Storage and Preservation of Longan Grapes
摘要
Abstract
To explore the impact of diverse harvest periods on the quality of table grapes during storage and determine the optimal harvest period for'Longan'grapes in the Zhangye production area of Gansu province,based on the maturity monitoring of'Longan'grapes,they were harvested at various times and treated with 1.5%carboxymethyl chitosan for coating and preservation during storage.By measuring indicators such as total soluble solids,reducing sugar,titratable acid,rot rate and weight loss ratio,the change rates of each indicator during the storage period were as the evaluation response values,and the effects of different harvest periods on the preservation efficacy of grape storage were investigated.The results demonstrated that the grapes harvested in period Ⅱ(October 12th)had the lowest weight loss rate and rot rate during storage,which were 10.07%and 34.07%,respectively;the decline rates of reducing sugar,total soluble solids and hardness were the slowest,which were 10.1%,5.6%and 29.8%,respectively.The'Longan'grapes in the Zhangye area should be harvested on October 12th,as they should possess strong storage performance.关键词
