Thermo Scientific Chromatography Consumables Help Detect Waste Oil

Gutter oil refers to all kinds of inferior oils in life. Long-term consumption may cause cancer and is extremely harmful to the human body. Due to the considerable economic temptation, some people still take the risk of selling gutter oil. In response to the strong public response to the gutter oil problem, the General Office of the State Council issued a document in July 2010, deciding to organize a pilot project on the resource utilization and harmless treatment of urban kitchen waste such as gutter oil. On September 13, 2011, the Chinese police cracked a major case of using "gutter oil" to produce and sell.

In the process of cracking down on "gutter oil", the gutter oil detection index system developed by the food safety monitoring unit played a significant role. The detection personnel used modern analytical and testing methods such as chromatography, spectral analysis, physical and chemical analysis and gene identification technology to conduct a comprehensive screening of more than 80 technical indicators, and identified four categories of polycyclic aromatic hydrocarbons, cholesterol, conductivity, specific genes, and more than 20 items with important identification significance. The detection system established on this basis provides effective technical guarantees for the safety of edible oil for the people.

Thermo Fisher Scientific, as a leader in the chromatography industry, is committed to making the world cleaner, safer and healthier. It is our unshirkable responsibility and obligation to make our best efforts to contribute to food safety. Therefore, Thermo Fisher Scientific has formulated the most favorable promotion plan for the chromatographic consumables involved in the detection of waste oil, providing testers with efficient and economical testing products.
