PURPOSE: A functional component enhancement method for cactus is provided to inject more than two kinds of enzymes for the fermentation. CONSTITUTION: More than two kinds of enzymes are injected into a cactus extract for fermentation. The enzymes are Aureobasidium pullulans and Candida utilis SY8-M2-1. Functional components in cactus are selected from beta-glucan and glutathione. 100 parts by weight of the cactus extract is mixed with more than 5 parts by weight of mixed culture liquid of the Aureobasidium pullulans and Candida utilis SY8-M2-1, and the mixture is cultured at 30-40°;C for 15-30 hours. The cactus extract is processed with cellulase, and the reaction is performed at 30-70°;C for 3-7 hours.
