Preparation method of low-fat low-lactose buffalo milk protein base material

The invention discloses a preparation method of a low-fat low-lactose buffalo milk protein base material, and relates to the technical field of milk product processing. The preparation method comprises the following steps: (1) taking raw cow milk, preheating, degreasing with a film, pasteurizing, and cooling to obtain skim milk; (2) adding Nurica lactase into the skim milk for hydrolysis, and performing enzyme deactivation and cooling to obtain a primary hydrolysis material; (3) adding Bonlacta lactase into the primary hydrolysis material for hydrolysis, and performing enzyme deactivation and cooling to obtain a secondary hydrolysis material; and (4) adding glucose oxidase into the secondary hydrolysis material for hydrolysis, performing enzyme deactivation, cooling to room temperature, adding a rice extract, performing uniform mixing, performing sterilization, and performing spray drying so as to obtain the buffalo milk protein base material. By adopting the preparation method, the buffalo milk protein base
