Process method for brewing vinegar by fermenting yellow serofluid

The invention discloses a process method for brewing vinegar by fermenting yellow serofluid. According to the technological method, bean curd yellow serofluid is subjected to enzymolysis through immobilized protease, so that protein in the bean curd yellow serofluid is subjected to enzymolysis to form oligopeptide, absorption is facilitated, and nutrition and health are achieved; cellulase is adopted for performing enzymolysis treatment on the bean dregs, protein sources and dietary fibers in the bean dregs are fully utilized, and the finished vinegar is endowed with rich dietary fibers; the yellow serofluid after enzymolysis and the bean dreg filtrate after enzymolysis are treated by microwave heating, so that on one hand, enzyme inactivation is promoted, on the other hand, volatilization of aldehyde substances is promoted, the purpose of removing beany flavor is achieved, and the sensory quality is improved; the finished vinegar prepared by the method is rich in amino acid and nutrient substances, has a hea
