Food testing can be divided into two categories, one is to test the quality of the product; the other is to test the hygiene of the product. The testing of this type of project is relatively difficult and requires high investment. Hygiene items include microorganisms, additives, harmful elements, agricultural residues, animal residues, toxins, etc.
microorganism:
The construction of a microbiology laboratory should be arranged in accordance with the requirements of the biological laboratory equipment and equipment specifications. Necessary equipment includes clean bench, incubator, autoclave, electric furnace, etc. Other equipment is configured according to specific testing items.
Additives and Harmful Elements:
Some projects can use chemical methods, but if you want to meet the current international food hygiene requirements, you should purchase gas chromatography-hydrogen flame detector, liquid chromatography-ultraviolet/visible light detector, atomic absorption instrument-graphite furnace detector, atomic fluorescence instrument Wait.
Residual pesticides:
The detection of residual pesticides by gas chromatography is indispensable. To detect organochlorine pesticides, an electron capture ECD detector is required; to detect organophosphorus pesticides, a flame photometric FPD detector or a nitrogen-phosphorus NPD detector is required. Now there are more and more items of pesticide residue detection, in order to improve the versatility, it is recommended to configure a capillary column split/splitless inlet and install a capillary column. In order to control the quality of raw materials and products for export, food processing enterprises can be equipped with gas chromatography-mass spectrometers.
Residual veterinary drugs:
If the detection of residual veterinary drugs is carried out, there are not many items and many batches, and an enzyme-linked immunosorbent instrument can be configured. For export food enterprises with a certain scale, it is best to configure a liquid chromatography-tandem mass spectrometer.
