Method for desalting corn soaking water

The invention discloses a corn soaking water desalting method, which belongs to the field of corn deep processing, is used for desalting corn soaking water, and comprises the following steps: preparing phytic acid-free corn soaking water by a resin adsorption method, filtering the phytic acid-free corn soaking water by a ceramic membrane to obtain a stock solution A and a permeate A, and separating and filtering the stock solution A by a spiral-wound membrane to obtain a stock solution B and a permeate B; carrying out acid hydrolysis on the permeate B to obtain hydrolysate, adjusting the pH value of the hydrolysate through an alkaline substance to obtain a precipitate, filtering the solution containing the precipitate to obtain a filtrate, carrying out amino acid adsorption by adopting adsorption resin to obtain a solution, and eluting to obtain an eluent containing amino acid components; and performing low-temperature vacuum concentration on the stock solution A, the stock solution B and the eluent to obtain
