Description

Preparation method and application of plant essential oil detoxication agent
Technical Field

Mycotoxins can be produced either in the crop field, such as fusarium toxins, or during harvesting and storage, such as aflatoxins, etc., and the growth of mold in grains and feeds and the production of toxins are affected by a number of factors, such as climatic conditions, crop variety, susceptibility of the crop, type of mold, damage to insects or chemicals, etc., and subsequent procedures. After animals eat feeds contaminated by mycotoxins, various acute or chronic toxicities often occur, and some diseases occur, mainly liver cancer and kidney, estrogen disorder syndrome, immunosuppression and the like. The production performance is represented by reducing feed intake, reducing nutrient absorption, affecting feed conversion rate, causing diarrhea, reducing immune function and animal reproductive performance, causing great loss, and the residual toxins of animals can also affect human health.
In order to solve the pollution problem of feed and raw material mycotoxins, on one hand, the quality of the feed raw material is controlled, and the occurrence of toxin transformation is prevented; another aspect is the detoxification of feed materials that have been subjected to mycotoxin contamination. However, mycotoxins are produced in various links of growth, processing, transportation and storage of feed raw materials, so that mildew-proof work is difficult to effectively carry out.
The method for reducing or eliminating mould pollution in production practice mainly comprises a physical detoxification method, a water washing method for removing, a heating detoxification method, a radiation method and the like, wherein chemical detoxification methods such as acid, alkali, acetaldehyde, an oxidant, ozone and the like are used for degrading toxins, and biological detoxification methods such as a mode of fermenting by using certain alcohols and microorganisms are adopted. Most of these methods are not practical, cost-effective, efficient, timely and safe to implement.
The main component types of the mycotoxin adsorbent are mineral adsorbents, yeast cell walls, enzyme preparations, active carbon, plants, nutrient methods, high-molecular substances, compounds thereof and the like, and the most commonly used mycotoxin adsorbent mainly comprises aluminosilicate, montmorillonite and bentonite, but has weak adsorbability to zearalenone, fumagillin and ochratoxin, has no selectivity to adsorbability to a large amount of vitamins and trace elements, thereby influencing the absorption of vitamins and trace elements, and also influencing the digestion of animals.
