Problems solved by technology

According to relevant analysis results, the adsorption rate of aflatoxin B1 by adsorption products can reach 70% to 85%, but the adsorption rate of zearalenone is only 20% to 30%. The degradation rate of B1 can reach 100%, and the degradation rate of zearalenone can reach more than 90%, but the in vitro culture time to achieve the above effect needs to be more than 24h, which deviates greatly from the actual production conditions, and the safety of the strain sex to be verified

Embodiment 1

[0027] A mycotoxin adsorbent comprises the following components in parts by weight: 30 parts of sodium montmorillonite, 5 parts of medicinal activated carbon, 40 parts of cell wall of Saccharomyces cerevisiae and 37 parts of licorice.

[0028] The mycotoxin adsorbent is prepared by the following preparation method:

[0029] 1) Glycyrrhizae is pulverized into fine powder through an ultrafine pulverizer, and sieved through a 200-mesh sieve to obtain licorice powder;

[0030] 2) Weigh sodium-based montmorillonite, medicinal activated carbon, Saccharomyces cerevisiae cell wall, and licorice powder in proportion, and add them to a single-shaft paddle mixer at an ambient temperature of 20-25°C and a humidity of 60%-70% Mix for 5 minutes under certain conditions to obtain the mycotoxin adsorbent.

Abstract

The invention discloses a mycotoxin adsorbent. The mycotoxin adsorbent comprises the following components in parts by weight: 30-50 parts of bentonite, 1-5 parts of activated carbon, 30-40 parts of an additive A and 5-39 parts of an additive B, wherein the additive A is a yeast cell wall, the additive B is licorice roots or plant extracts, and the plant extracts are radix astragali polysaccharide or ginseng polysaccharide. The invention further discloses a preparation method of the mycotoxin adsorbent. The mycotoxin adsorbent disclosed by the invention has high-efficient adsorption effects on aflatoxins and zearalenone, and is suitable for short-term addition use to raw materials with serious mycotoxin pollution and breeding sites.

Description

technical field [0001] The invention belongs to the field of feed additives, and in particular relates to an adsorbent for adsorbing mycotoxins and a preparation method thereof. Background technique [0002] Mycotoxins are secondary metabolites produced by molds during their growth and reproduction. Among the more than 300 known mycotoxins, more than 20 are harmful to animal growth, especially aflatoxin B1 (AFB1), corn Zearalenone (ZEN) and vomitoxin are the representatives, which can lead to the reduction of animal growth performance, clinical disease, and even death and other serious consequences. [0003] Due to the current abnormal global climate, the mold pollution of feed raw materials has been aggravated. Since November 2014, corn by-products and fermented feed samples have been seriously contaminated with zearalenone and vomitoxin, and wheat and wheat bran have been seriously polluted with vomitoxin. In August 2015, Kemin CLS test sample results showed that the con...
