Abstract

The invention provides a degrading method of pesticide residues in ginseng oral liquid by utilizing radiation, and belongs to the technical field of pesticide residue degrading treatment in Chinese herbal medicines. The method is to treat the ginseng liquid containing multiple pesticides (methidathion, fonofos, diazinon, phosalone, imidacloprid, fenpropathrin totally six forbidden or restricted pesticides) by adopting an electronic accelerator which produces high-energy electrons in the radiation condition, so that the pesticides are degraded, wherein the energy of the electron accelerator is 7.5MeV and the electron radiation dose is between 2 and 15kGy; and concentrations of the six pesticides are detected by an ultra-high performance liquid chromatography-tandem mass spectrometer after radiation so as to determine the degrading effect. By adopting the method, residues of the six pesticides in the ginseng oral liquid can be reduced or eliminated efficiently, quickly and safely, and the degrading rates of the six related pesticides are over 30 percent in 15kGy radiation, so that the limit standard of European Union and other countries can be achieved. The degrading method provides a good idea for degrading of pesticides in ginseng oral liquid, and has wide development prospect.

Description

technical field

[0001] The invention belongs to the technical field of degradation treatment of pesticide residues in Chinese herbal medicines, and in particular relates to an electron beam irradiation method for degrading methapon, fenfofos, diazinon, thionon, imidacloprid, and cyanide in commercial products of ginseng oral liquid Irradiation degradation method of six banned and restricted pesticides including permethrin. Background technique

[0002] my country is the birthplace of Chinese herbal medicine. After years of unremitting efforts, foreign countries have gradually affirmed the important position of Chinese herbal medicine in the field of medical and health care. However, the problem of pesticide residues in Chinese herbal medicines has become the main reason why the export of Chinese herbal medicines is blocked in my country, and it is the most difficult barrier to overcome this precious cultural heritage of our country to the world. At present, developed countr...
