Abstract:
The present invention relates to a preparation method of flavonoid-based phenol compounds with enhanced antioxidant, lightening, and antibacterial activity by a low temperature atmospheric pressure plasma treatment. The present invention can improve a physiological functionality of vegetable flavonoid-based phenol compounds by using the plasma treatment. Therefore, the flavonoid-based phenol compounds with enhanced physiological functionality can be used for functional foods having antioxidant and lightening capabilities; a pharmaceutical composition for prevention or treatment of disease generated by an oxidation process of active oxygen; and the manufacture of an antibacterial product and a cosmetic product.
