Fresh-Keeping Effect of Kojic Acid on Rape

Abstract:

Kojic acid is a metabolite from some common microbe, it is a natural preservative. The kojic acid has broad prospects in the storage and preservation of fruits and vegetables. In this study, using different concentrations of kojic acid sprayed the surface of rape and stored at room temperature, observed phenotypic changes. Then the CAT and POD activity, chlorophyll content and weight loss rate were determined in rape treated by kojic acid. From the overall trend, compared with the water, spraying 0.5% and 1% kojic acid to a certain extent reduce chlorophyll loss of rape, water evaporation and dry matter decrease was slowing down, and maintains the appropriate activity of CAT and POD. It means that the kojic acid has obviously effect on rape preservation.
