Studies on Changes of Quality of Red Globe, Kyoho Grapes after Harvest

Abstract

Abstract: Storage quality of postharvest Red Globe and Kyoho grapes after harvest was studied. The results showed that during the storage and at the room tempreture, the content of reducing sugar, titrataboe acid, and VC decreased gradually, where as, changes of titratable acid and VC content were negatively related to the time of storage significantly. Fresh keeping agent treatment could lower the loss of reducing sugar, titratable acid and VC. Red Globe grapes had longer storage life than Kyoho obviously. Under the condition of 0℃ + CT - 2 + polyethylene film, the rate of sound fruit of Kyoho was 87.8% after 135 days storage; and that of Red Globe was 92. 7% after 150 days storage.

Key words: Fresh grapes , Storage quality
