Drainage oil detector is ** testing standards have not yet been introduced

The reporter learned from the Ministry of Health that in accordance with the unified deployment of the State Council Food Safety Commission Office, the Ministry of Health is fully organizing scientific research to identify and identify methods for the inspection of waste oil. In accordance with the uniform deployment of the State Council Food Safety Office, 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 Food Bureau, and the China Center for Disease Control and Prevention. The expert group on inspection methods including oil and fat processing, food safety, health inspection, chemical analysis, and other related organizations has conducted a scientific demonstration of the testing methods developed by relevant technical organizations.

It is understood that the inspection of waste oil is of high technical difficulty. Domestic and foreign countries have not yet established a scientifically feasible method for the inspection of waste oil. The demonstration of verification methods is still in progress.

Tsu City: Someone is selling "drainage oil detectors"

“Someone recently promoted a waste oil detector to us. One quotation would cost 10,000 yuan. Later, we consulted an expert to know that it was a scam. The instrument was actually an edible oil quality tester, and it could not detect the waste oil at all. "Yesterday, the newspaper hotline received a report from Mr. Zhao, a person in charge of a catering company in the city, saying that they had almost bought a so-called "drainage oil detector" at a high price.

"Disposal Oil Detector" has a quotation of 10,000 yuan recently. The oil incident has heightened the catering industry as a whole. Some traders have seen business opportunities from it, and they have widely promoted so-called waste oil detectors. “We recently received more than a dozen phone calls to sell waste oil detectors. The other said that as long as this kind of instrument is inserted into the oil, we can immediately know if the oil used is a waste oil. After listening to it, we find it very magical. The customer talked about the oil color change. This instrument was just enough for the customer to rest assured that the meal, but a 10,000 yuan offer made us a little hesitant." Mr. Zhao said, they later consulted an edible oil testing agency in the city, the other told them, At present, there is no standard for the detection of waste oil in the country, let alone the equipment for the detection of waste oil. "Fortunately, at the time, it was not cheated to buy such a high price."

Actually it was just an edible oil quality tester. At that time, what kind of instrument was promoted to Mr. Zhao? The reporter saw from the information Mr. Zhao got. This instrument is like a large mobile phone with a large screen. Below the instrument there is something like a metal antenna. The data shows that as long as the metal part is immersed in the test oil, it can immediately determine whether it is a waste oil.

In response, the staff of an edible oil testing agency in the city stated that according to the data, this kind of instrument is not a newly developed testing instrument, nor is it used for the detection of waste oil. This is just an ordinary rapid detection instrument for edible oil quality. It can only detect the proportion of polar substances in edible oils (polarity is a quality index for judging whether edible oils can continue to be used), and for a variety of complex components in waste oil, this instrument cannot do anything about it.

At present, there are no instruments that can quickly detect the gutter oil. According to reports, the current inspection standards for waste oil have not yet been introduced. In the case of oil spills cracked by the public security department, the technicians of the Beijing Food Safety Monitoring Center have repeatedly tested and demonstrated that in addition to the national sanitary standards for edible vegetable oil, more than 20 special test indicators for four categories were established to search for waste oil. The trace has initially established an index system for the detection of waste oil, and this detection system uses a large number of high-end detection instruments and comprehensively uses modern analytical testing methods such as chromatographic analysis, spectral analysis, physical and chemical analysis, and gene identification techniques. Rapid detection of edible oil quality cannot do so much at all.

Waste oil generally contains animal oil, which is easily solidified and crystallized. When the temperature is low in autumn and winter, if edible oil is solidified and crystallized, it is very suspicious.

Cooking oil produced from cooking oil often has a spicy taste.
