Embodiment 1

[0022] Embodiment 1 A kind of preparation method of aflatoxin-free rice, its steps are as follows:

[0023] A. Rice harvesting

[0024] Choose sunny days to harvest rice, and choose fresh rice without pollution and mildew as raw materials

[0025] B. The first combined treatment of ozone water, chlorine dioxide and ultrasound for detoxification treatment. The combined ozone water concentration is 1.8g / L; the chlorine dioxide concentration is 8g / m3; the ultrasonic intensity is 100w. Process for 1 minute.

[0026] C. Shelling

[0027] Use manual or mechanical husking methods to hustle rice to obtain rice;

[0028] D. The second combined treatment of rice with ozone water, chlorine dioxide and ultrasonic; the parameters are the same as the first time.

[0029] The obtained rice was used to prepare refined oil in which no aflatoxins were detected.

[0030] The rice obtained after the above process has been tested to have completely degraded the aflatoxin, and the aflatoxin-p...

Embodiment 2

[0032] A preparation method for removing aflatoxin peanuts, the steps are as follows:

[0033] A. Peanut Harvesting

[0034] Choose sunny days to harvest peanuts, and choose fresh peanuts without mold and rot as raw materials

[0035] b. to clean

[0036] Wash the harvested Huang Sheng in time to remove mud and impurities;

[0037] C. centrifugal dehydration

[0038] Use a stainless steel three-legged centrifuge to remove the moisture on the surface of the peanuts in time after cleaning;

[0039] D. The first joint treatment of ozone water, chlorine dioxide and ultrasound:

[0040] The shelled peanuts that have been dehydrated are treated with ozone water, chlorine dioxide and ultrasound for detoxification. The combined ozone water concentration is 2g / L; the chlorine dioxide concentration is 3g / m3; the ultrasonic intensity is 100w. Process for 0.5 min.

[0041] E. Shelling

[0042] The shelled peanuts that have undergone detoxification treatment are shelled by mechanic...

Embodiment 3

[0047] A preparation method of aflatoxin-free feed, the steps are as follows:

[0048] A. The various feeds produced by the existing processing methods are subjected to the combined action of ozone water, chlorine dioxide and ultrasound for detoxification treatment. The ozone content of the combined ozone water is 2g / L; the concentration of chlorine dioxide is 8g / m3; the intensity of ultrasound is 100w. Process for 2 minutes.

[0049] B. Vacuum packaging

[0050] Vacuum-pack the feed that has been treated by the combined action of ozone water, chlorine dioxide and ultrasound.

[0051] The feed obtained after the above process has been tested to greatly reduce the aflatoxin content or completely remove the aflatoxin.

Abstract

The invention discloses an aflatoxin degradation method. According to the method, substances containing aflatoxin are processed by combining ozone water, chlorine dioxide and ultrasonic to obtain a sample with the reduction of the aflatoxin. The processing method adopted by the invention is as follows: the ozone water contains 1-3g / L of ozone, and the concentration of chlorine dioxide is 3-8g / m<3>; and the aflatoxin and aspergillus flavus in peanuts and rice can be completely removed by ultrasonic intensity being 100w. According to the method disclosed by the invention, the operation is simple, the degradation effect is good, the degradation time is short, and the used chemical reagents are few; and the afatoxin degradation method is used for the degradation of the aflatoxin contained in agricultural products and the like and the control of the content of the aflatoxin contained in the agricultural products, and has extremely high application value and market potential.

Description

technical field [0001] The invention relates to a method for degrading aflatoxin, in particular to a method for degrading aflatoxin by using a composite process. Background technique [0002] Aflatoxin (AFT) is a kind of toxic secondary metabolite produced by Aspergillus flavus, Aspergillus parasitica, etc. It is one of the most harmful mycotoxins to humans and animals. A large number of data confirm that aflatoxin has a strong toxic effect on the liver tissue of humans and animals, and can lead to liver cancer and even death in severe cases. Among them, aflatoxin B2 is currently the most powerful carcinogen known in the world, and is listed as a 1A carcinogen by the WHO, which will be extremely harmful to humans. [0003] Animal experiments have shown that aflatoxin can induce animal liver cancer, as well as stomach, kidney, rectum, breast, ovary and small intestine cancer. Among various aflatoxins, AFTB1 (C17H1206, molecular weight 312) is the strongest carcinogen discov...
