The Yangtze River Valley has been planting rice since ancient times, and people in these areas have always had a soft spot for the fragrant rice. As the most consumed food variety, rice plays an important role in people's daily lives, so its quality and safety is of paramount importance. In order to ensure the food security of rice and continuously improve the quality of rice, it is necessary to test the quality of rice in many fields such as production and inspection. The tools used in the testing are all kinds of rice quality testing instruments. Here is a look at rice testing. What are the commonly used instruments?
Important indicators for routine testing of rice include: broken rice, imperfect grains, maximum impurities, pesticide residues, moisture, mutual mixing, cadmium, arsenic, lead, mercury, etc., which can be divided into pesticide residue detection, pollutants, mycotoxins, physical and chemical Projects, genetic modification, etc. To detect different indicators of rice, different detection instruments are needed. The commonly used instruments mainly include: rice appearance quality detector for detecting the appearance of rice , and organophosphorus pesticides for cereals in the grain (dichlorvos, omethoate). Etc.), organochlorine pesticides (chloropharmil, triadimefon, etc.), carbamate pesticides (aldoxime, carbofuran, etc.), pyrethroid pesticides (methyrin, cypermethrin, etc.), etc. Gas chromatograph and high performance liquid chromatograph for pesticide residue detection, gas chromatography-mass spectrometer for detecting whether aflatoxin B1, ochratoxin A and its content in rice are exceeded, and detecting rice and its products Whether the gene contains a gene sequencer of CaMV 35S, NOS, Bt, and the like.
The above only contains some of the rice detection instruments. In fact, with the development of society and the continuous improvement of food safety quality requirements, the quality and safety testing of rice is becoming more and more strict. Therefore, in order to comprehensively evaluate the quality of rice, it is usually necessary to establish professional rice testing. The laboratory is used for professional testing, and the indispensable instruments are mainly used instruments such as rice appearance quality detectors.
