Problems solved by technology

[0003] Traditional physical and chemical methods are used to treat aflatoxin-contaminated agricultural products or feed; however, these methods have problems such as incomplete detoxification, reduced nutritional value, high cost, and poor applicability
In recent years, biological control of aflatoxin pollution has become a research hotspot. Many microorganisms that inhibit the growth of Aspergillus flavus, inhibit the production of toxins by Aspergillus flavus and degrade aflatoxin have been isolated and cultivated; however, most of these microorganisms are limited to the laboratory research stage , there are problems such as strict reaction conditions, large differences in the degradation rate of Aspergillus flavus, and uncontrollable degradation effects in actual industrial applications.

Abstract

The invention discloses a starter for degrading aflatoxin, its preparation method and application, and belongs to the technical field of toxin degradation. The fermentation agent for degrading aflatoxin of the present invention is composed of composite microbial bacterial agent and synergist according to the weight-to-volume ratio of 4:1; The silk yeast and bacillus licheniformis are mixed according to the weight ratio of 1-5:1-5:3-8:3-8. The starter of the present invention can effectively degrade aflatoxin B in crops or agricultural products 1 , the degradation products are safe and will not have toxic effects on animals.

Description

technical field [0001] The invention belongs to the technical field of toxin degradation, and in particular relates to a starter for degrading aflatoxin, its preparation method and application. Background technique [0002] Aflatoxins are mainly secondary metabolites produced by Aspergillus flavus (A.flavus) and Aspergillus parasiticus (A.parasiticus), which are derivatives of dihydrofuranocoumarins, and were approved by the World Health Organization (WHO) in 1993. Cancer Research Institute delineated as a class I carcinogen. [0003] Traditionally, physical and chemical methods are used to treat aflatoxin-contaminated agricultural products or feeds; however, these methods have problems such as incomplete detoxification, reduced nutritional value, high cost, and poor applicability. In recent years, biological control of aflatoxin pollution has become a research hotspot. Many microorganisms that inhibit the growth of Aspergillus flavus, inhibit the production of toxins by As...
