Problems solved by technology

However, there are also some defects: firstly, it is not suitable for the degradation of residual chloramphenicol in livestock and poultry products; secondly, the irradiation dose needs to be maintained at a relatively high level (8-10kGy) to effectively degrade meat animals and aquatic products The residual chloramphenicol in the environment consumes a lot of energy and costs; and high doses of radiation can easily cause the quality of meat animals and aquatic products to decline.

Embodiment 1

[0025] Embodiment 1 A kind of irradiation degradation method of livestock and poultry product antibiotic

[0026] A) Cobalt-60 gamma irradiation treatment: The original packaged livestock and poultry products are irradiated with cobalt-60 gamma rays, the radiation absorbed dose is 1.5kGy, and the radiation absorbed dose uniformity is 1.3;

[0027] B) Periodic forward and reverse current treatment: place the above-mentioned irradiated livestock and poultry products in a forward DC electric field at normal pressure for 16 seconds, and then place them in a reverse DC electric field at normal pressure for 8 seconds. The reverse current density of forward current and normal pressure is 120A / m 2 .

Abstract

The invention belongs to the technical field of irradiation, and particularly relates to a degradation method of antibiotics of livestock and poultry products through irradiation. The degradation method comprises the following steps of firstly, performing radiation treatment with cobalt-60 gamma, and then performing periodical backward electric current treatment. Based on radiation treatment, periodical backward electric current treatment is combined, so that on one hand, the residual quantity of chloramphenicol can be reduced to 0.1[mu]g / kg with low irradiation absorption dose, and the chloramphenicol can be thoroughly reduced to a third-class product; and on the other hand, the livestock and poultry products after radiation treatment do not generate the phenomenon of yellowing, and the degradation method is free from influence on the quality of the livestock and poultry products, so that marked progress is obtained.

Description

technical field [0001] The invention belongs to the technical field of radiation, and in particular relates to a radiation degradation method for antibiotics of livestock and poultry products. Background technique [0002] my country is a big producer of livestock and poultry products. my country's livestock and poultry products will face more intense competition in international trade after joining WTO, and the problem of drug residues in animal-derived foods, especially antibiotic residues, has become a major trade issue for the export of livestock and poultry products in my country. One of the technical barriers. The problem of excessive antibiotic residues in livestock and poultry products has not only caused huge economic losses to our country, affected the health of the people, but also reduced consumers' credibility of domestic livestock and poultry products. [0003] Long-term or excessive use of veterinary drugs, especially antibiotics and hormones, as feed additive...
