Study on the Changes of Antioxidant Activity of Fruit Enzymes with Different Formulas Resistance to Environmental Pollution

Enzymes were made with different fruit combinations, and their total phenol content and free radical scavenging ability (DPPH·, ·OH, O2-) were determined. The results show that the enzyme has good antioxidant properties. And with the extension of the fermentation time, total phenol content and free radical scavenging ability all show a trend of increasing first and then decreasing. From the comprehensive point of view of total phenol content and free radical scavenging effect, Group 3 has the best effect, and it is best to drink at 40-60 days.
