Brewer's yeast culture and fermentation technology thereof

The invention discloses a brewer's yeast culture and a fermentation technology thereof. The fermentation technology of the brewer's yeast culture in the invention comprises the following steps: (1) shake flask seed culture; (2) liquid deep oxidized fermentation; (3) liquid low-temperature anaerobic fermentation; (4) solid enzymolysis aerobic fermentation; (5) solid anaerobic fermentation; and (6)solid-state high-temperature wall-breaking autolysis, and thus obtaining the brewer's yeast culture. Sufficient fermentation is carried out on brewer's yeast in the stages of liquid fermentation and solid fermentation, and more metabolites are generated, so that the product effect is improved. The brewer's yeast culture prepared through the method provided by the invention has unique aromatic odor, and after high-temperature wall breaking, probiotic ingredients such as yeast cell walls and contents can exert the effects, of food calling, irritability resistance and intestinal prebiotics, whichare not owned or embodied
