A compound ferment production process and a product thereof are applicable to the technical field of foods. The formulation of the product comprises fruit vegetable ferment raw juice, 
plant ferment raw juice, corn ferment, peas ferment and multielement alditol. The production process comprises the following: a step of preparing fruit vegetable ferment liquid, during which, selecting and 
cutting fresh 
fruits and vegetables into slices or pieces, blending the slices or pieces, adding apple vinegar on the slices or the pieces, and storing the 
fruits and vegetables hermetically at 
room temperature to prepare the fruit vegetable ferment raw juice through natural 
fermentation; a step of preparing the 
plant ferment liquid, during which, selecting, chipping and blending herbal plants, adding common salt into the sliced herbal plants, and storing the sliced herbal plants hermetically at 
room temperature to prepare the 
plant ferment raw juice through natural 
fermentation; and a step of 
fermentation and 
product processing, during which, taking the fruit vegetable ferment raw juice, the plant ferment raw juice, the corn ferment and the peas ferment, carrying out the second fermentation at 
room temperature, adding the multielement alditol during the second fermentation, using a sealed 
jar during the fermentation, preparing the compound ferment product after a postmaturation process, and preparing the liquid, powdery and 
solid particle ferment through mechanical 
processing and forming. The process and the product thereof which have a novel and scientific design and long-term maturation through the natural fermentation can increase the 
vitality of the ferment, facilitate the demand of a 
human body and improve the health of the 
human body through frequent edibility.
