Description

Method for efficiently degrading mycotoxin in corn steep liquor
Technical Field
The invention relates to the technical field of degradation of mycotoxin in corn steep liquor, in particular to a method for efficiently degrading the mycotoxin in the corn steep liquor.
Background
Corn is widely applied to the fields of food, feed, organic fertilizer and medicine processing after being processed, soaking is the primary process of corn starch deep processing, and the soaking process directly influences the subsequent product yield and quality.
Corn steep liquor is a product of a corn starch soaking process, is one of byproducts of corn deep processing enterprises, and generates a large amount of corn steep liquor every year. Although corn steep liquor is rich in soluble protein, trace elements, vitamins and some precursor substances and contains about 40-50% of solid substances, the high content of mycotoxin in the corn steep liquor limits the application of the corn steep liquor in the food, feed and medicine industries. After the mold contaminates the food and produces toxins, ingestion of such food by humans can cause various damages to human health. In the breeding process, the growing speed of fattening pigs is slow, false oestrus of sows, diarrhea of suckling piglets, the laying rate of laying hens is reduced, the milk quality does not meet the requirement and the like. The main reasons for this are mycotoxin irritation. At present, methods such as montmorillonite adsorption, biological fermentation, enzymolysis and the like are mostly adopted, but the effect is not ideal.
Disclosure of Invention
In view of the technical defects, the invention aims to provide a method for efficiently degrading mycotoxin in corn steep liquor by mixing the corn steep liquor with ammonia water or NH4 +Or urea is mixed to degrade the contents of aflatoxin B1, zearalenone and vomitoxin in the corn steep liquor, so that the high-efficiency utilization of the corn steep liquor is realized, and the requirements of feeds, foods and medicines are met.
In order to solve the technical problems, the invention adopts the following technical scheme:
a method for efficiently degrading mycotoxin in corn steep liquor is characterized by comprising the following steps:
1) mixing the corn steep liquor with ammonia water or NH4 +Or urea according to a ratio of 1: 0.01-1: 10, mixing in a ratio range;
2) placing the mixed liquid in a closed container;
3) the closed container is placed at the ambient temperature of 1-500 ℃ for 1 minute-100 hours.
Preferably, the corn steep liquor is mixed with ammonia water or NH in the step 14 +Or the mixing ratio of the urea is 1: 1, mixing the liquid in the step 3 at the temperature of 150 ℃ for 2 hours.
Preferably, the ammonia water, NH4 +The concentration range of the urea is as follows: 0.01 to 100 percent;
preferably, the corn steep liquor in the step 1 is mixed with ammonia water or NH4 +Or the pH value of the liquid after urea mixing is 2-13.
Preferably, the corn steep liquor is 0.01-99.99% of the corn steep liquor after the corn steep liquor is concentrated.
The method has the advantages of greatly reducing the toxin in the corn steep liquor and greatly expanding the application range of the corn steep liquor.
