Effect of Sulfur Dioxide Treatment on Storage Quality of Red Grape

Article Preview

Abstract:

The aim of this study was to determine the efficacy of several alternative postharvest treatments to sulfur dioxide (SO2) in storage quality during cold storage of red grape.The three kinds of treatment were 0μL/L (CK),3000μL/L(TR1),5000μL/L(TR2).The results showed that SO2 damagement effected on physiological metabolic and physiological quality of grapes significantly.It can inhibit the rise in pH of grapes,harm the integrity of cell membranes,increase conductivity and malondialdehyde content and stimulate the activity of polyphenol oxidase. But right amont of SO2 had a positive effect on strage and preservation of grape.
