The treatment also enhanced the activities of antioxidant enzymes including superoxide dismutase, catalase and ascorbate peroxidase, andmaintained lower levels of superoxide anion, hydrogen peroxide, and malondialdehyde. In addition, the1,1-diphenyl-2-picrylhydrazy (DPPH) radical-scavenging activity, total phenolic, ascorbic acid, total sugarcontent, as well as titratable acidity (TA) were increased by blue light exposure.
