Waste edible oil generally refers to all kinds of inferior oils existing in life, such as recycled edible oil and reused frying oil. The biggest source of waste oil is the grease trap in the sewer of large hotels in the city. Long-term consumption may cause cancer and do great harm to human body. The General Office of the State Council issued a document on July 20 10, and decided to organize the pilot work of resource utilization and harmless treatment of urban kitchen waste such as gutter oil. On 20th11September13rd, China police cracked the case of illegal cooking oil. In February, 2065438+0165438, the Ministry of Health publicly collected the detection methods of "gutter oil" from the society. In May, 20 12, four instrumental methods and three rapid detection methods that can be used on the spot were preliminarily determined.

Waste oil, the garbage flowing quietly in urban sewers. Some Taoist priests processed it into "cooking oil" on the table. They fished out a lot of dim, turbid and reddish paste from there every day. These foul-smelling garbage can be turned into clear "edible oil" after only one night of filtration, heating, precipitation and separation, and finally returned to people's dining tables through low-price sales. This three-no product, called "waste oil", is still composed of triglycerides, but the toxic substances that cause disease and cancer are much more than the real edible oil.

"Waste cooking oil" is a kind of non-edible oil with poor quality and extremely unsanitary. Once you eat "gutter oil", it will destroy people's white blood cells and digestive tract mucosa, causing food poisoning and even serious consequences of cancer. Therefore, it is strictly forbidden to use "gutter oil" in the field of edible oil. However, driven by interests, there are indeed some unscrupulous traders who disregard people's lives and process "gutter oil" privately and sell it to some small restaurants as edible oil at low prices, which brings great harm to people's body and mind. Therefore, the name "gutter oil" has become synonymous with all kinds of inferior oil that brings harm to people's lives.
