Problems solved by technology

At the same time, hydrated aluminosilicate and bentonite adsorbents need to be added in large quantities when used, which not only takes up too much formula space, but also brings new problems, such as the nutritional content of adsorbed minerals affects the taste and increases heavy metals content, thereby polluting the feed itself more

Abstract

The invention discloses a nano-composite mycotoxin adsorbent, a preparation method thereof and an application of the adsorbent, and belongs to the technical field of feed additives. The adsorbent comprises the following components in weight percent: 50-60% of montmorillonite powder, 20-30% of plant fatty acid ester, 5-10% of sodium salt and 5-10% of yeast cell walls, wherein the total weight percent of the components is 100%. The preparation method includes the steps: uniformly mixing the montmorillonite powder, the sodium salt and the plant fatty acid ester and then heating mixture for activation, reaction and extrusion kneading; adding the yeast cell walls; and uniformly stirring, extruding, drying, grinding and sieving the components to obtain the adsorbent. The adsorbent has large adsorption surface area and super-strong adsorption force, can effectively adsorb various mycotoxins and is convenient to use, green and environmentally friendly. The preparation method is simple in process, energy consumption is reduced, and raw materials are free from pollution.

Description

technical field [0001] The invention relates to the technical field of feed additives, in particular to a nanoscale composite mycotoxin adsorbent and its preparation method and application. Background technique [0002] Mycotoxins are toxic metabolites produced by molds in their contaminated food. They can enter humans and animals through feed or food, causing acute or chronic toxicity to humans and animals, and damage the body's liver, kidneys, nerve tissue, hematopoiesis, etc. tissue and skin tissue. At the same time, mycotoxins can be produced not only when crops are immature, but also when crops are mature but stored in poor conditions, causing great harm to human and animal bodies. At present, the quality of feed raw materials in our country is declining year by year, and a large number of raw materials are polluted by water and mold, which makes the rich nutrients in feed very susceptible to mold pollution and mildew. Moldy feed will not only affect its palatability,...
