Preparation method of residue-removed soybean milk

The invention provides a preparation method of residue-removed soybean milk. The preparation method comprises the following steps: (1) pulping, specifically, mixing peeled soybeans with RO water, and performing oxygen-isolated pulping to obtain pulp; (2) removing beany smell, specifically, performing lipoxygenase passivation on the pulp obtained in the step (1) to obtain beany smell removed soybean milk; (3) removing residues, specifically, performing centrifugal separation on the beany smell removed soybean milk obtained in the step (2) for residue removal to obtain residue-removed soybean milk; (4) performing enzyme deactivation, specifically, performing trypsin inhibitor inactivation on the residue-removed soybean milk obtained in the step (3) to obtain enzyme-deactivated soybean milk; and (5) deodorizing, specifically, deodorizing the enzyme-deactivated soybean milk obtained in the step (4) through negative pressure to obtain the residue-removed soybean milk. According to the preparation method of the res
