Food Examination Laboratory Planning

Food examination laboratory planning

Food examination can be divided into two categories: 1. Product quality inspection; 2. Product sanitation inspection, which is relatively difficult with high investment.

Health projects involve the preparation of food, inspecting, and testing in the laboratory.

Health projects include microorganisms, additives, harmful elements, agricultural residues, animal residues, toxins, etc.

1

Microorganisms :   A microbiology laboratory should be laid out in accordance with the requirements of the specified standards of biological laboratory instruments and equipment. The necessary equipment includes a clean workbench, incubator, high-temperature sterilizing oven, electric furnace, etc. Other devices are configured according to the specific test items.

2

Additives and harmful elements :   Some of the projects may involve the of chemical methods. However, to comply with the current national standards of food hygiene, you should consider purchasing equipment such as gas phase chromatograph with a hydrogen flame detector, liquid phase chromatography with an ultraviolet-visible light detector, atomic absorption spectrometer with a graphite furnace detector, and atomic fluorescence spectrometer, among others.

3

Residual pesticides :   Gas chromatography is needed for detecting residual pesticides. The laboratory should be equipped with electron capture detector (ECD) if you want to detect organic chlorine pesticides. Nitrogen-phosphorus detector (NPD) or flame photometric detector (FPD) should be equipped to detect organic phosphorus pesticides. Nowadays, there are more and more pesticide-detecting items to be done. In order to improve the generality, purchasing a capillary column split-splitless injection port and installing a capillary column are suggested. Gas chromatography-mass spectrometer can be purchased for export food processing enterprises to control the quality of raw materials and products.

4

Animal Residues :   When it comes to detecting veterinary drug residues, there are few detection items and numerous batches. Therefore, it is suggested that a set of ELISA Reader should be purchased and configured. For export food enterprises that have a certain scale, a liquid chromatography-tandem mass spectrometer is a better choice.
