In recent years, due to the improvement of living standards, the general public is paying more and more attention to health problems. People who are poisonous to people’s healthy food such as poisoned milk powder and poison capsules do not want to enter the mouth. On the other hand, in order to improve the output of agricultural products, shorten the growth cycle, improve the appearance, taste, etc., the use of various pesticides, veterinary drugs, additives, and preservatives in the field of food production and distribution has made food safety issues increasingly prominent, and various types of acute poisoning. Incidents continue to occur. Based on the above, food safety issues have attracted the attention of government departments at all levels, and Tongda analysis machine will help you solve problems.
Main purpose of food detector
Applicable to all levels of health supervision departments, food safety regulatory agencies, agricultural and sideline products quality testing centers, food production enterprises, agricultural production bases, farmers markets, food and drug administration, industry and commerce administration, entry and exit inspection and quarantine bureaus and other departments for food safety Monitor.
Food detector main function
Food safety tester can hang white block, nitrite, nitrate, hydrogen peroxide, cyclamate, edible oil peroxide value, edible oil acid value, formaldehyde, borax, heavy metal lead, heavy metal mercury, heavy metal chromium, heavy metal arsenic in food. Heavy metal cadmium, saccharin (sodium), lemon yellow, sunset yellow, amaranth, carmine, temptation red, bright blue, indigo, histamine, bacterial toxin, base nitrogen, malondialdehyde in lard, iodized salt content, Industrial methanol, ethanol, soy sauce total acid, vinegar total acid, benzoyl peroxide, aluminum in flour, aged food, rice freshness, milk protein, milk powder protein, tea polyphenols and other food additives and food safety inspection items Quick detection and multi-functional food safety monitoring system.
1 Know as much as possible about the situation on the spot and speculate: such as the incubation period and the passing situation. The number and symptoms of poisoning. Ingestion of food and symptoms of the same eater. It is speculated whether it is ingestion or poisoning. In case of accidental eating; should carefully observe the raw materials of the food, the surrounding environment of the storage, the processing place of the food and the packaging container of the tool, and speculate on the source of the poison that may be ingested. In the case of poisoning; the poison of the suspicious individual may be inferred from the work of the suspicious individual.
2 sampling principle
Sampling for preventive monitoring: Sampling depends on the situation. Liquid foods are sampled by uniform (mixed) method. Solid foods can be sampled by uniform method or orientation method.
Toxic substance detection and sampling: take the part suspected of containing the most toxic substances for sampling, such as suspicious substances and vomits that have been eaten by the poisoned person. It is difficult to detect the gastric lavage or excrement on site, and should be sent to the laboratory for testing. .
The amount of sample should be considered for review and further confirmation of retention.
3. Inspection precautions
First pre-test, blank test in the pre-test.
When toxic substances are found, they should be sent to the laboratory for verification by various methods and compared with known toxicants.
All kinds of reagents should be observed and identified regularly, and should be replaced as soon as they fail.
