This invention relates to the fields of agricultural product processing and bio-feed technology, specifically to a method and application for detoxifying corn steep liquor. The method includes: subjecting a mixture of corn steep liquor, a composite color-protecting agent, and a composite catalyst to a first reaction; allowing the reaction system after the first reaction to stand in a mixture with a composite adsorbent; subjecting the mixture containing the reaction system after the stand-in reaction and a composite enzyme preparation to stand-in treatment, mixing treatment, and enzymatic hydrolysis; and subjecting the mixture containing the reaction system after the enzymatic hydrolysis and an activated composite microbial agent to anaerobic fermentation. This method employs a multi-stage chemical-enzyme-fermentation linkage process, achieving efficient detoxification of corn steep liquor while significantly improving flavor and nutrition. This method synergistically removes mycotoxins and sulfites, and enhances palatability and probiotic value through fermentation transformation of off-flavor substances and enrichment of small peptides and lactic acid. The process is simple and requires no adsorbent separation.
