Problems solved by technology

[0005] Most of the existing feed mycotoxin additives are based on adsorption carriers, such as zeolite, etc., and the adsorption performance of the adsorption carrier is helpful to adsorb the mycotoxins in the feed on the adsorption carrier, and then complete the detoxification effect. However, the feed The degree of desorption of mycotoxins is closely related to the amount of the adsorption carrier added. If the amount of the adsorption carrier is large, it will cause a greater burden on the weight of the feed

preparation example Construction

[0038] The preparation process of modified starch is as follows:

[0039] (1) Add 10 parts of acrylic acid, 10 parts of methyl acrylate, 10 parts of butyl acrylate, and 70 parts of water to a three-necked flask and stir, stirring at a speed of 100r / min, and a nitrogen flow at a speed of 20ml / min, heat up to 45℃ under nitrogen atmosphere and keep it for 10min;

[0040] (2) Add 0.5 part of polyoxyethylene hydrogenated castor oil and 0.3 part of sodium lauryl sulfate to step (1) at a rate of 0.1 part per minute, wait until it is evenly stirred, and heat up to 65°C;

[0041] (3) Add 0.2 part of sodium peroxide to step (2), heat up to 75°C under stirring, and react for 2h;

[0042] (4) Keep the state at 75°C, add starch, soak for 2 hours, and then dry it at a temperature of 60°C.

Embodiment 1

[0044] (1) Weigh 40 parts of modified starch, 10 parts of sodium carboxymethyl cellulose, 10 parts of yeast glucan, 10 parts of soy protein, 10 parts of calcium propionate and 2 parts of olive oil, and set aside;

[0045] (2) Use a pulverizer to pulverize the modified starch to a particle size of 500 mesh; then put 40 parts of the pulverized modified starch and 10 parts of sodium carboxymethyl cellulose into the three-dimensional mixer, and adjust the speed to 220r / min, stirring for 1h;

[0046] (3) Continue to put 10 parts of yeast glucan, 10 parts of soy protein, 10 parts of calcium propionate and 2 parts of olive oil into the three-dimensional mixer, adjust the speed to 150r / min, stir for 1 hour, and prepare the premix;

[0047] (4) Dry the premix in an oven at 50°C, and wait until the water content drops to within 5%;

[0048] (5) Use a pulverizer to pulverize the dry premix in step (4) into uniform powder.

Embodiment 2

[0050] (1) Weigh 45 parts of modified starch, 13 parts of sodium carboxymethyl cellulose, 15 parts of yeast glucan, 10 parts of soy protein, 10 parts of calcium propionate and 3 parts of sunflower oil, and set aside;

[0051] (2) Use a pulverizer to pulverize 45 parts of modified starch to a particle size of 500 mesh; then put 45 parts of pulverized modified starch and 13 parts of sodium carboxymethyl cellulose into the three-dimensional mixer and adjust the speed to 220r / min, stirring for 1h;

[0052] (3) Continue to put 15 parts of yeast glucan, 10 parts of soy protein, 10 parts of calcium propionate and 3 parts of sunflower oil into the three-dimensional mixer, adjust the speed to 150r / min, stir for 1h, and prepare the premix;

[0053] (4) Dry the premix in an oven at 50°C, and wait until the water content drops to within 5%;

[0054] (5) Use a pulverizer to pulverize the dry premix in step (4) into uniform powder.

Abstract

The invention discloses a mould detoxifier, a preparation method thereof, and a feed additive. The mould detoxifier comprises the following components in parts by weight: 40 to 50 parts of modified starch, 10 to 15 parts of sodium carboxymethyl cellulose, 10 to 20 parts of yeast glucan, 20 to 25 parts of light powder, and 1 to 3 parts of auxiliary agent. The provided mould detoxifier has a better mould removing effect, and the using amount is less for processing a same amount of feed.

Description

Technical field [0001] The invention relates to the technical field of feed additives, in particular to a mold detoxifier, a preparation method thereof, and a feed additive. Background technique [0002] Feed mildew is a global problem. Due to different climates and geographical locations, the types of mycotoxins are also different. In warm temperate regions such as China, most of Europe and North America, toxins such as vomiting toxin and zearalenone are mainly produced in farming fields; In hot flashes like India, feeds mainly produce aflatoxin during storage. With the impact of global warming, mycotoxins have become a common phenomenon that exists everywhere. Therefore, the degree of attention to mycotoxins is increasing, and food safety issues have also been paid more attention. [0003] According to the assessment of the Food and Agriculture Organization of the United Nations, the annual economic loss caused by mold contamination of feeds in the world amounts to 100 billion ...
