Abstract
To clarify the reactive oxygen metabolism of fresh-cut fruits and vegetables,fresh-cut cabbages were taken as materials,exogenous ethylene and methyl jasmonate(MeJA) were used as signals to treat fresh-cut cabbages,and then stored at 4℃. The changes of H2O2 and O2-were analyzed and the activity of super oxygen dehydrogenises(SOD),peroxidase(POD),catalase(CAT),ascorbate peroxidase(APX) were measured as main enzymes in the metabolism. Results showed that the reactive oxygen including H2O2 and O2-were inhibited by ethylene and MeJA respectively. The activity of SOD and APX could be improved after treated with ethylene,but the activity of POD and CAT were inhibited. Antioxidant enzymes including SOD,POD,and CAT were inhibited after MeJA treatments. The influence of MeJA on APX during 12h were different,the activity of APX was promoted in the beginning but inhibited in the end. Between two treatments,ethylene could promote the antioxidant activity of fresh-cut cabbage obviously.
