Problems solved by technology

[0003] At present, there is no way to remove chloramphenicol residues in casings. The use of chloramphenicol can only be strictly controlled in the process of pig breeding. However, this method cannot completely solve the problem of chloramphenicol residues in casings. Chloramphenicol, mainly uses gamma rays

Embodiment 1

[0015] A method for irradiating and degrading chloramphenicol in natural casings: irradiating casings containing chloramphenicol after pickling, draining, and bagging the finished product at room temperature, and adopting the continuous irradiation method of automatic back and forth accumulation type suspension chains , the electrical parameter of the suspension chain speed is 12-24Hz, and the irradiation time is 2-12h; the irradiation dose of casings per bag is 2-9kGy; the unevenness of the same batch of products treated with the same irradiation dose is 1.1-1.4.

[0016] The casing is preferably one that does not contain sundries, has no peculiar smell, has no mildew, and has a good color.

[0017] The electrical parameter of the suspension chain speed is preferably 18Hz.

[0018] The unevenness of the same batch of products treated with the same radiation dose is preferably 1.2.

Embodiment 2

[0020] Choose casings that do not contain sundries, foreign matter, and mildew, and do different irradiation doses (0kGy, 2kGy, 4kGy, 6kGy, 8kGy) for different initial contents of chloramphenicol in casings (0.1mg / kg, 0.5mg / kg, 1mg / kg, 10mg / kg, 50mg / kg), the irradiation parameters are set as follows: the continuous irradiation method of the hanging chain with automatic front and rear turning and storage is selected, the electric parameter of the hanging chain speed is 20Hz, and the samples with different irradiation doses The irradiation time is 0, 2.5, 5, 7.5, and 10 hours respectively; the irradiation dose of each bag of casing is 0kGy, 2kGy, 4kGy, 6kGy, 8kGy respectively; the unevenness of the same batch of products treated with the same irradiation dose is 1.2 .

Abstract

The invention relates to a radiation-induced degradation method for chloramphenicol in natural casing, belonging to the technical field of radiation degradation. The method is characterized by carrying out radiation at normal temperature on a natural casing containing chloramphenicol obtained after pickling, draining, bagging of finished products, and selecting an automatic turning over back and forth power-and-free hanging chain continuous radiation mode with a hanging chain speed electrical parameter of 12-24 Hz to radiate for 2-12 h, wherein the radiation dose of each casing is 2-9 kGy, and the non-uniformity of the same batch of products processed by the same radiation dose is 1.1-1.4. The motion mode of the radiation bagged casing is automatically controlled, thus the radiation efficiency is raised, the processing cost is reduced, and pesticide and veterinary drug residues in food can be effectively degraded. According to the invention, the radiation-induced degradation for chloramphenicol has the advantages of low cost and convenient operation, the radiation has no significant influence on color difference of casings, tensile strength, and shear strength, the adverse influence on the casings caused by external environmental conditions can be effectively overcome, the color of the casings is protected, the economic loss is reduced, and the production benefit is increased.

Description

technical field [0001] The invention relates to a method for degrading chloramphenicol residues in natural casings, in particular to a method for degrading chloramphenicol through irradiation technology, and belongs to the technical field of irradiation degradation. Background technique [0002] Natural sausage casing is an edible but perishable product rich in protein and fat, which is processed from the esophagus, stomach, small intestine, large intestine and other organs of healthy livestock. And chloramphenicol (Chloramphenicol), as a kind of broad-spectrum antibiotic drug, is effective to aerobic bacteria, anaerobic bacteria, chlamydia, mycoplasma, rickettsia etc., and price is lower, is widely used in human, animal etc. For the treatment of various infectious diseases, due to the long-term use of chloramphenicol, there is a small amount of chloramphenicol residue in the casing, which causes very serious side effects on the human body. There are very strict regulations...
