The invention discloses a composite 
enzyme beverage and a preparation process method thereof. The composite 
enzyme beverage is prepared from five cereals, 
fruits and vegetables, 
edible plants and edible fungi as main raw materials through common 
fermentation; three-step 
fermentation is realized by using microzyme, 
acetic acid bacteria and 
lactic acid bacteria; and substep 
fermentation for different strains is adopted at different stages in the manufacturing process, so that the demands of a 
human body on the efficacies of health and 
nutrition are met. According to the composite 
enzyme beverage disclosed by the invention, the mixture ratio of the raw materials is more gentle, more pure natural organic raw materials are used and the three-step fermentation is realized by the microzyme, the 
acetic acid bacteria and the 
lactic acid bacteria; and the composite enzyme beverage retains original vitamins and 
carbohydrate of the 
fruits and vegetables, is rich in various B-group vitamins and various amino acids, is a 
nutrient necessary for eliminating the 
human fatigue and particularly benefits people suffered from 
chronic disease syndrome. Particularly after coarse grains are fermented, insoluble dietary fibers can be dissolved into small molecular substances which are easily digested and absorbed by the 
human body, and thus the 
digestion and intake of nutritive substances by the 
human body can be enhanced.
