| Abstract: | The effects of sucrose,CaCl 2,citric acid,ascorbic acid and gallates on peroxidase(POD) and lipoxygenase(LOX) activity in longan were studied by monofactorial experiment and homogeneous design. The rusults showed that inhibitions of POD and LOX activity appeared when concentration of each reagent was to certain extent. Certain interacted inhibitions of citric acid,ascorbic acid and gallates on POD and LOX in longan appeared. When the concentration of citric acid,ascorbic acid and gallates was 6.1?0.5?0.05?g/L respectively,the activity of POD and LOX in longan were inhibited by 83.3% and 99.5% respectively. |
