Abstract

The invention discloses a method for detecting residual tranquilizer medicines in a meat product. The method comprises the following steps: extracting and purifying by adopting a C18 solid phase extracting column, and then detecting by adopting a gas chromatography-mass spectrometer (GC-MS), so as to rapidly and exactly detect out the variety and the content of the residual tranquilizer medicines, including seven tranquilizer medicines, namely, diazepam, oxazepam, estazolam, alprazolam, triazolam, phenobarbital and promethazine, in the meat product. The method is suitable for detecting multiple tranquilizer medicine residues in complex substrate meat products such as sausage; the method has the advantages of being low in detection limit, accurate, fast, easy and convenient in operation and economic in detection cost, and can be developed and applied in detection mechanisms.

Description

【Technical Field】 [0001] The invention relates to a method for detecting residual drugs in meat products, in particular to a method for detecting residual tranquilizer drugs in meat products. 【Background technique】 [0002] Sedatives are drugs that can relieve excitement, have inhibitory effects on the central nervous system, reduce or eliminate animal restlessness, and restore tranquility. Commonly used drugs are: diazepam, nitrazepam, oxazepam, phenothiazines, chlorpromazine, promethazine, perphenazine, and diazepam, phenobarbital Wait. In addition to their sedative effects, many of these drugs are also a type of growth promoters, which are used as animal feed additives. When pigs and other animals eat the feed with the above-mentioned tranquilizers, they can make them sleepy and less active, promote their rapid growth, and But it changes the meat quality. These drugs can cause adverse reactions to the human central nervous system. my country and many other countries have li...
