Description
Technical field
The present invention relates to a kind of pesticide detection device, and in particular to a kind of Fast Determination of Pesticide Residue dress on food
Put and its detection method, belong to technical field of food detection.
Background technology
With the improvement of people ' s living standards, in recent years, people also increasingly pay attention to food Pesticide Residue.For
This, many countries have formulated MRL (MRLs) of the agricultural chemicals in food, and the inlet and outlet of crops require that agricultural chemicals is residual
Stay the MRLs of various countries to be less than.With China joined WTO, the inlet and outlet of crops will constantly expand, the inspection of food residues of pesticides
Mark standard integrates with international standard and just becomes more and more important, thus analyze detect food agricultural chemicals remain important meaning
Justice.
The pollution by pesticides of food surface is controlled and first have to detect the distribution kind of agricultural chemicals and dense with administering
The information such as degree.It is that a needs are for a long time and huge that pollution by pesticides, which is detected, classified using conventional chemical analysis method
The work of manpower and materials.And detected with laser Induced Fluorescence Technology, its sensitivity is higher, it is simple and easy, reality can be carried out
When detection on the spot.As Patent publication No CN201589749U discloses a kind of embedded instrument for detecting pesticide residue through, its feature exists
In, including persticide residue is transformed into telecommunications by photodetector system, data collecting system and touch-screen, photodetector system
Number, it is amplified to send data collecting system that analog-signal transitions are detected into data signal, data signal transmission touch-screen
As a result display and testing process control, the photodetector system by laser diode, optical filtering, cuvette, silicon photocell, put
Big circuit composition, the data collecting system are made up of single-chip microcomputer, data acquisition chip and communication chip, and the touch-screen is selected
TPC7062KX, communicated with data collecting system by serial ports RS232, detected in the photodetector system through silicon photocell
