People eat for food. Food is the basic guarantee for people's lives, but in recent years, food safety incidents have occurred frequently. Among them, one of the more common hidden dangers is mycotoxins.

Mycotoxins mainly refer to the toxic metabolites produced by molds in the foods they contaminate. They can enter humans and animals through feed or food, causing acute or chronic toxicity to humans and animals, and damage the liver, kidneys and nerve tissues of the body. , hematopoietic tissue and skin tissue.

In the food industry, there are about 200 kinds of mycotoxins that have been reported to cause harm to humans and animals. About 25% of the world's cereals are contaminated with various molds every year. The major hazards are aflatoxins, vomiting toxins, and cockroaches. Aspergillus, zearalenone, fumonisin, T-2 toxin, etc., the pollution of agricultural products and feeds by these toxins was listed as an important source of foodborne diseases by the World Health Organization in 2002. Therefore, it is necessary to use an instrument to detect mycotoxins.

To prevent mycotoxins, it is very important to control and keep raw materials, and to detect them in food processing, transportation and storage. Well-known companies in the industry said that the method of confirming mycotoxins mainly includes thin layer chromatography (TLC), gas chromatography (GC), high pressure liquid chromatography (HPLC) and various combined technologies such as GC-MS. LC-MS, etc.; currently, the analysis of mycotoxins in national standards mainly includes HPLC-FLD and HPLC-MS/MS.

In 2017, an instrument and meter company in China also developed a quantitative test system for mycotoxin fluorescence, which passed the authoritative verification of the National Food Bureau Scientific Research Institute, benchmarking food industry standards LST6111-2015, LST6112-2015 and LST6113-2015, Breaking the long-term monopoly of foreign products in this field has promoted the progress of domestic food testing instruments.

According to statistics, in 2017, the demand for food safety testing equipment in China will be nearly 68.5 billion yuan, and will increase to 77.4 billion yuan in 2018. At the same time, with the continuous advancement of modern science and technology, especially the continuous development of immunology, biochemistry and molecular biology, the mycotoxin detection technology is also becoming more and more fast and accurate, and the operation is simple.
However, compared with foreign-funded enterprises, domestic food testing instruments still have gaps in technology and product maturity. In 2017, the import volume of China's detection and analysis instruments reached US$6.938 billion, while the export scale was only US$1.228 billion, and the trade deficit continued to expand.

In order to ensure food safety, China has established a number of rapid inspection rooms and testing centers to promote the construction of food safety systems. But in some areas, there is still much room for improvement. For example, in the food safety of campus, it has not received enough attention, and many campus food safety incidents have been exposed. According to statistics, in Shanghai alone, more than one million preschool children and primary and middle school students dine in school on a daily basis. If food safety cannot be guaranteed, the consequences are unimaginable. In addition, food testing needs to be taken seriously in the increasingly popular take-away industry.

As people's food safety awareness becomes stronger, food testing will also receive more and more attention. For related companies, it is necessary to pay close attention to new technologies and new methods, continuously improve technological innovation, and introduce applicable testing technologies and testing instruments to achieve their own rapid development.
