Embodiment Construction

[0009] When the aquatic products are irradiated by electrons, the packaging specification of shrimps is 60×40×25cm, which is consistent with the irradiation box. When the density is 0.5, the thickness should not exceed 20cm. When cobalt-60 gamma rays are used for irradiation, the size of the packing box is not limited. Shrimp irradiated with rays (electron beams, or cobalt-60γ rays) should be placed in a cold storage at -18°C (or a warehouse in the area to be irradiated); a piece of FWT-60 film dosimeter should be attached to the upper right corner of each box before irradiation; aquatic products Under the original packaging, it enters the irradiation room at a certain speed through the transmission device. The irradiation room is irradiated by radiation (electron beam, or cobalt-60γ-ray), and the absorbed dose is 6-kGy; Dose, and calculate the uniformity of radiation absorbed dose, which is required to be less than 1.4; at the same time, take a reserved sample to check whethe...

Abstract

A method for degradating the residual chloromycetin in aquatic products features that the energy (6 Mev) electronic beam or the energy (1.33 Mev) Co-60 gamma ray is used to irradiate the aquatic products. When the high energy (over 10 Mev) is used, the irradiation processing uses the electronic accelerator. Its advantage is high effect (93% or more).

Description

Technical field [0001] The invention relates to the application of atomic energy technology and the field of radiation processing. Background technique [0002] At present, some countries have stricter regulations on the maximum content of residual chloramphenicol in aquatic products, stipulating that the content should not be detected by testing instruments; some countries have regulations below 0.1 μg / Kg; some countries have no regulations. Therefore, the amount of residual chloramphenicol has become a focus of aquatic products in international trade. Chloramphenicol, molecular weight 323.13, molecular formula C 11 h 12 CI 2 N 2 o 5 , is an antibiotic drug with broad-spectrum antibacterial effect. In the aquaculture industry, it is often used to prevent and control various aquatic diseases, thus causing environmental pollution of chloramphenicol and residues in aquatic products. Although my country's Ministry of Agriculture issued a document in 2001 to prohibit the ...
