On September 16, the police from Langjiazhuang Police Station of the Public Security Bureau of Kunming Anning City discovered a black factory suspected of producing "ditch oil"

The reporter learned from the Ministry of Health that, in accordance with the unified deployment of the Office of the Food Safety Commission of the State Council, the Ministry of Health is fully organizing scientific research and research to identify "waste oil" inspection methods.

        7 departments work together to tackle key problems

        In accordance with the unified deployment of the Food Safety Office of the State Council, the Ministry of Health organized the Ministry of Science and Technology, the State Administration for Industry and Commerce, the General Administration of Quality Supervision, Inspection and Quarantine, the Food and Drug Administration, the Grain Bureau, and the China Centers for Disease Control and Prevention to jointly study and formulate a "waste oil" inspection method demonstration plan , And established an inspection method demonstration expert group including authoritative experts and related institutions in the fields of oil processing, food safety, sanitary inspection, chemical analysis, etc., to scientifically demonstrate the inspection methods developed by related technical institutions.

        It is understood that the inspection of "waste oil" is very technically difficult. A scientific and feasible "waste oil" inspection method has not been established at home and abroad, and the verification of the inspection method is still in progress.

        The current national standard has a big loophole

        Industry experts pointed out that there are loopholes in the current supervision of "waste oil", which makes it easy for "waste oil" to get through. Taking the current national compulsory standard 2716-2005 "Hygienic Standard for Edible Vegetable Oils" as an example, according to the national standard, edible oil inspections usually test 9 indicators such as acid value, benzopyrene, and pesticide residues. And if only these 9 items are tested, "waste oil" may also be qualified. For example, the police recently seized a large amount of "waste oil" in Ninghai, Zhejiang and sent it for inspection. According to the current national standard inspection, only two of the 10 samples submitted for inspection were unqualified.

        Huang Hua, director of the R&D Office of the Beijing Food Safety Monitoring Center, said, "The producers of'waste oil' will add caustic soda during the processing according to the "Health Standards for Edible Vegetable Oil" to eliminate the acid value of'waste oil'. Cover up the unqualified indicators."

        The indicator system has been explored

        It is understood that currently, after screening more than 80 technical inspection items that may be involved in "waste oil", the Beijing Food Safety Monitoring Center has found four types of products including polycyclic aromatic hydrocarbons, cholesterol, electrical conductivity, and specific gene composition. The effective indicators of "waste oil" were checked, and an index system for "waste oil" inspection was initially established.

        The above-mentioned "waste oil" samples that were "qualified" by the national standard were tested according to these 4 types of indicators, and more than 10 carcinogens were detected.
