1. Heat treatment method For the cake raw materials, baking at 150 ° C for 30 minutes, or heating with microwave for 8-9 minutes, 48-61% of aflatoxin B1 and 32-40% of aflatoxin C1 can be destroyed. .
2, adsorption method clay, activated carbon and other adsorbents can absorb mycotoxin, reduce the absorption of the gastrointestinal tract.
3, the removal of mycotoxins is mainly concentrated in the grain of mold, damage, discoloration and insects, such as the selection of these grains, the toxin content can be greatly reduced. The feed is selected by mechanical or manual methods, the moldy feed is removed, and the mildewed feed is further dried to achieve the purpose of detoxification and mildew resistance.
4, the water washing method is repeatedly soaked and rinsed with water to remove water-soluble toxins. For granular raw materials such as corn and soybean, it can be rinsed with water after pulverization, or repeatedly rinsed with 2% lime water to remove mycotoxins.
How to prevent mildew
1. The water washing method is repeatedly soaked and rinsed with water to remove water-soluble toxins. For granular raw materials such as corn and soybean, it can be rinsed with water after pulverization, or repeatedly rinsed with 2% lime water to remove mycotoxins.
2. The application of the anti-mold agent to the processed feed ingredients and compound feed is extremely prone to mildew, so mold can be used to control mildew during processing. The commonly used antifungal agents are organic acids and extremely salty, among which propionic acid is the most widely used salt.
3. Control humidity to control the relative humidity of the water in the feed and the storage environment. The key to anti-mold measures for grain feeds is to quickly reduce the water content to a safe moisture range within a short period of time after harvest. Generally, the grain moisture content is below 13%, the corn is below 12.5%, and the peanut kernel is below 8%. The mold is not suitable for breeding, so the water content is called safe moisture. The safe moisture of various feeds is not the same. In addition, safe moisture is also related to storage temperature, which is negatively correlated.
4, to prevent insect bites, rodents using mechanical and chemical control methods to treat pests in the granary, and pay attention to the prevention of rats, because the insects or rat bites damage the grain so that the mold is easy to breed and cause mildew.
