Pork generally needs to go to the health and quarantine department for quarantine. Quarantine is divided into three procedures: pigs entering the factory, stocking and sending them to slaughter before slaughter. Meat involves breeding, feed management, epidemic prevention and quarantine. And there can be no problems in any link, especially the infected pork can't enter the market, otherwise it will bring great harm to the whole market.
2.？ Clenbuterol detection
Clenbuterol is not only a substance, but also a common name for a class of drugs. Clenbuterol hydrochloride is the most commonly illegally used clenbuterol. At present, the commonly used methods to detect clenbuterol residues based on instrumental means include high performance liquid chromatography (HPLC), gas chromatography-mass spectrometry (GC-MS), high performance liquid chromatography-mass spectrometry (HPLC-MS), capillary electrophoresis (ce) and so on.
3.？ Hanging white block detection
Sodium formaldehyde sulfoxylate is added to food for whitening and refreshing, but sodium formaldehyde sulfoxylate is forbidden to be added to food. The sodium formaldehyde sulfoxylate detector can detect the sodium formaldehyde sulfoxylate content. Add the soaking solution of the food sample into the colorimetric tube, and then add the chromogenic solution. By comparing with the color card, the content of sodium bicarbonate in food was determined. When the soaking solution is lavender or purplish red, the product quality is unqualified.
4.？ Humidity check
Moisture content directly affects the processing, storage, trade and consumption of fresh meat of livestock and poultry. Excessive water content in meat will aggravate the reproduction of bacteria and mold, which will easily lead to meat spoilage; However, in order to make huge profits, illegal traders inject more and more water and meat, which has become a major public hazard that seriously threatens people's health. In food distribution and supply companies, the moisture content of meat will be quickly detected by moisture detector to determine whether it belongs to water-injected meat.
5.？ Heavy metal detection
Because pigs eat unqualified feed in the feeding process and the heavy metal pollution in their living environment leads to the heavy metal exceeding the standard in their pork. Excessive heavy metal content in pork causes food safety problems. The detection mainly uses the pork heavy metal detector to quickly detect whether the heavy metal content in pork exceeds the standard, so as to judge the quality of pork.
6.？ Veterinary drug residue detection
Veterinary drug residue refers to the residue after injecting drugs into animals, which may threaten health after being ingested by human body, and may lead to fetal malformation, adolescent precocious puberty, cardiovascular diseases in middle-aged and elderly people, cancer and some food poisoning. This link mainly uses the veterinary drug residue detector to detect veterinary drug residues.
