Description

A kind of pesticide residue detection pretreatment device

Technical field

The present invention relates to food inspection device field, in particular to a kind of pesticide residue detection pretreatment device.

Background technique

Pesticide residue remains in pesticide parent, derivative, metabolism in environment, organism and food after referring to Pesticide use The general name of object, degradation product and impurity.The mainly some countries for causing vegetable pesticide residue amount exceeded forbid in vegetables produce The organophosphorus pesticide and carbamate chemicals for agriculture used, such as acephatemet, flolimat, thimet, parathion, parathion-methyl Deng.It is edible to will lead to people, animal acute poisoning accident containing food caused by a large amount of high poisons, highly toxic pesticide residual.Agriculture is eaten for a long time Medicine remains exceeded agricultural and sideline product, although not will lead to acute poisoning, may cause the slow poisoning of humans and animals, leads to disease The generation of disease induces cancer, or even influences the next generation.

The development of agriculture industrialization makes the production of agricultural product be increasingly dependent on the allogenes such as pesticide, antibiotic and hormone Matter.China's pesticide is high in the dosage of agricultural product, and the unreasonable use of these substances will lead to the agriculture in agricultural product Medicine residual is exceeded, influences consumer's edible safety, will cause consumer when serious and causes a disease, develops abnormal, or even directly results in It is poisoned to death.Excessive pesticide residues also will affect the trade of agricultural product, and Pesticide Residue is paid much attention in countries in the world, to each Pesticide residue all defines the limit standard being increasingly stringenter in kind agricultural and sideline product, and China's Agricultural outlet is made to face severe choose War.

Fast Determination of Pesticide Residue method is many kinds of at present, studies carefully and is broadly divided into two major classes for its principle: biochemical measurement Method and chromatographic detection.Wherein the enzyme inhibition rate method in biochemical assay is due to quick, sensitive, easy to operate, at low cost The features such as honest and clean, is listed in national proposed standard method (GB/T 5009.199-2003), it has also become to organic phosphorus and ammonia in fruits and vegetables Carbamate pesticide residue carries out one of the mainstream technology of live fast qualitative primary dcreening operation detection, has obtained more and more extensive answer With.

When detecting the pesticide residues such as vegetables, meat, fruit, the sample for symmetrical sample to finish is separately added into 2 kinds of quantitative examinations After agent, screw capping is successively upper, and scroll machine is shaken up, supersonic wave cleaning machine sufficiently cleans, supercentrifuge centrifugation；Then lid is backed out to take Lid is twisted after the third reagent is added in 15mL centrifuge tube in clear liquid, then successively upper scroll machine shakes up, supercentrifuge is centrifuged； Finally backing out lid takes supernatant to cross 0.22 micron of organic filter membrane into 1.5mL sample introduction bottle, and small bottle cap is twisted, measures agriculture to upper machine Medicine residue.

Since sample size is extremely more, pre-treatment work is many and diverse, time-consuming, and operation is manually that large labor intensity people often occurs For mistake, work quality is inefficient, now people can be replaced to operate the automation completing big batch pre-treatment and working there are no a kind of Device.
