The work aims to study the applicability of ozone fumigation methods in the Munage grape postharvest storage under refrigerated conditions. With Xinjiang Munage grape as the tested material, the control group respectively at 0 ℃ and −1 ℃, and the influence of 2.5 μL/L and 5 μL/L ozone fumigation on the storage effect and quality of Munage grape were studied. The results showed that the respiration intensity of Munage grape treated by 2.5 μL/L ozone fumigation at −1 ℃ was weak, and the fruit soluble solid content and titratable acid content were kept well during the storage. The decay rate of the fruit and the shattering rate were low. The rate of intact fruit after the storage was higher, which helped maintain the fruit quality. 2.5 μL/L ozone fumigation at −1 ℃ is the most suitable environmental storage parameter for Munage grape.
