Huashang Daily News reported on March 8, Xi'an, Mr. Guo, well-versed in the food processing industry, a chance he discovered a shocking secret. By chance, he discovered an amazing secret: after frying food with oil, the oil usually becomes cloudy or even spoiled, but at this time, if a substance is used in the frying oil, it will make the cloudy frying oil become clear, just like new oil. For this reason, he spent nearly a year to understand on the grounds that he wanted to start a food processing plant.
According to Mr. Guo's research, the substance is commonly known as "oil filtering powder," and its main function is to extend the service life of the oil, even if it is never scrapped.
Around February 2006, Mr. Guo contacted a retailer selling "oil filtering powder" through the Internet, the retailer's name is Chen, who specializes in wholesaling and retailing "oil filtering powder" in Ningbo. After a number of calls to communicate, Chen sent Mr. Guo e-mail information on the "oil filtering powder" to explain the real situation, the results let Mr. Guo was surprised. According to his understanding, the use of edible frying oil may be suspected of "second-hand oil". With these questions, Mr. Guo will reflect the matter to the Huashang Daily reporter.
Ningbo City, operating "oil filtering powder" Chen boss sent Mr. Guo the following text in the information:
"Mr. Guo: ...... If you deal with a large amount of oil every day, the quality of the food requirements are high, the cost savings are obvious. The cost savings are only obvious. There are many export food companies use our products at the request of customers ...... From the current situation, the domestic food hygiene standards are not strictly supervised and enforced, so the vast majority of manufacturers engaged in domestic sales, their frying oil can be used for 3 days, 7 days, and even never scrapped! Although it has long exceeded the standard, there is a serious danger to the human body, but saving costs. Therefore, our products are currently the customer base of some large enterprises, especially export enterprises ......" is "Chen × ×".
Reporters in Chen provided another "treatment of frying oil to maintain the quality of oil research report" also saw that this treatment of frying oil "oil filtering powder", the first time to join the time is to use the new oil a day later.
According to the test conditions in the report, frying oil refers to the oil after use, and to add the "oil filtering powder", the oil's free fatty acid concentration (equivalent to the acid value) is less than 1.5%. Only below 0.7%, 2% of the oil volume per day to add; between the two, you can increase the amount of addition; higher than 1.5%, it is recommended to discard.
Under normal use, frying oil is used for 2-3 days, the concentration of free fatty acids in the oil will be greater than 2%.
At the same time, the report pointed out that the use of "oil filtering powder" treatment of frying oil is: complete control of the acid value (the report notes: artificially control the acid value in order to delay the acid value of the oil to reach the end-of-life standard), more than 70% of the oil color. (The report states that the reduction of oil color is also one of the means of prolonging the use of frying oil) and other seven effects, and they found in their own tests that from January 2003 until now, they have not discarded a single drop of oil. The "oil filtering powder" is the United States Dallas Group production.

Likewise, the store manager did not show law enforcement officials the corresponding "oil filtering powder" use of approved procedures.
Law enforcement officials: never seen "oil filtering powder" this product
To make the turbid frying oil within a short time to become clear, Yulin City Health Bureau law enforcement officials said that they have been to the KFC store many times before to check, but never seen the "oil filtering powder" this product
This is the first time in the world that the KFC store has been used in the past. "
Law enforcement officials said they had been to KFC several times before, but had never seen this kind of product.
Law enforcement officers from 11 p.m. on the night of February 27 began to check, until 2 a.m. on the 28th, and repeatedly urged the KFC store Zheng manager to provide "oil filtering powder" purchase and allow the addition of legal materials, but the Zheng manager site did not provide the required materials, but only provided the internal operation of the process flow.

Filtering before the test paper has 2 cells yellow color, and after the "oil filtering powder" "polishing", frying oil color is obviously brighter, clearer, law enforcement officers test paper test found that the test paper only 1 cell yellow, which is enough to show that the "oil filtering powder This is enough to show that the "oil filtering powder" plays an important role.

It is reported that the production and management or use of food additives do not meet the use of health standards or relevant regulations, in accordance with the "Food Sanitation Law," the provisions of Article 44 to be punished.
Food experts say:
Repeated use of frying oil is easy to produce carcinogenic substances
For KFC to use the "oil filtering powder", Shaanxi Normal University, Professor Qiu Nongxue Department of Food Engineering, Li Jianke interview with this reporter, said that they have not yet seen this kind of product, and at present in the country, there is no research findings in this regard. There is no research findings in this area, there is no repeated use of domestic products in the edible oil filtration, according to the name, it should be physical adsorption. But on the "treatment of frying oil to maintain the quality of oil research report", the two professors said that this report is not complete.
They believe that if it only acts as a physical adsorption, it does not have a great impact on food, but the repeated use of frying oil, the nutritional value of the oil will certainly be greatly reduced. Vegetable oil repeatedly used at high temperatures, high-temperature oxidative rancidity will occur, rancid fats and oils on the body's cytochrome enzymes and other enzyme systems will have a detrimental effect. Long-term intake of rancid and deteriorated fats and oils is detrimental to health.
Meanwhile, repeated heating will oxidize the edible oil, which is prone to rancidity. In the experiments of the report, only the concentration of free fatty acids (acid price) in the food oil was tested, while the peroxide value, another important physicochemical index for measuring the oil, was not reflected in the report. The control of these indicators serves to maintain the freshness of the cooking oil so that the oil meets the standards required by the state. The repeated heating of the oil, grease is prone to produce other harmful substances, such as french fries, may produce acrylamide and other carcinogens, and fried chicken, may produce benzopyrene and other carcinogens, but the report, does not reflect the harmful substances produced by the test.
According to the two professors, in order to use the product in China, you should obtain a certificate from the relevant state departments before you can use it. But whether the filtered frying oil will contain harmful substances needs to be determined by testing the oil before and after the use of the "oil filtering powder".
Similarly, the director of the National Food Safety Laboratory in Shaanxi, Shaanxi Province, the head of the physical and chemical laboratory of the CDC also holds the same view, cooking oil repeatedly high-temperature frying of food, can produce carcinogenic substances such as benzo(a)pyrene.
The person in charge of the introduction of the current frying oil, the country has only begun to study the development of standards, and included in China's food safety program. In the past two years the province has been doing work in this area, only the collection of doughnuts, collection points distributed in Xi'an, Baoji, Yan'an, Ankang, Weinan Fuping, Xianyang Jingyang and other places.
