The carcinogens of crushed "poisonous" oil exceeded the standard by 28.8 times.

Green, Low Carbon and Life

Aflatoxin exceeding the standard, poor production environment, adulteration and adulteration have always been the "stubborn disease" of bulk peanut oil in Huizhou. During March 15 this year, this paper launched an investigation report on this problem. The Food and Drug Administration of Huizhou immediately organized a comprehensive inspection of the whole city's bulk oil workshop. However, recently, reporters received reports from consumers that the market of bulk peanut oil in Huizhou is still in chaos. To this end, Nandu reporters again visited Huizhou bulk peanut oil market, and randomly selected 7 samples for inspection. The testing report issued by Guangzhou Analytical and Testing Center showed that the content of aflatoxin B 1 in all seven samples exceeded the standard. Among them, the content of aflatoxin B 1 in one sample from the crusher of Huicheng wheat market reached 596 ug/kg, which was 28.8 times higher than the standard.

Flies Flying in the Oil Press Workshop

On the morning of October 16, Nandu journalists and two colleagues from Southern Television Station visited seven local oil extracting workshops in the central market, wheat market and cold water pit market on the Henan shore as consumers. These ports for processing and selling bulk earth-pressed peanut oil are mostly household workshops with small pavement, mostly less than 20 square meters, poor conditions and worrying sanitary conditions. They have no improvement compared with what reporters visited in March this year. There are even a lot of flies on some oil extractors.

Most of the crude oil is packed in large oil barrels beside the crusher. The price ranges from 10 yuan to 15 yuan per kilogram. If someone purchases it, the archivist will bail it out and bottle it to the customer. They sell a variety of containers for bulk crushing oil, including mineral water bottles, orange juice bottles, recycled brand edible oil packaging bottles and so on. There are also individual workshops using disposable plastic bottles, but the bottle body does not have any product identification, such as production date, shelf life and other basic information.

In a local oil press in the central market of Henan, the reporter said that he wanted to squeeze two kilograms of peanut oil now. The shopkeeper refused, saying that squeezing too little was not worth booting. "Whoever squeezes two kilograms for you will get 100 kilograms, if you want two kilograms, you will get 10 yuan per kilogram." Finally, the reporter had to buy two kilograms of pressed peanut oil and leave.

Pressing oil from mildewed peanuts and even mixing it with ditch oil

During the reporter's visit to the local oil squeezing workshop, he saw many citizens come to buy peanut oil. Some people have questioned that peanuts are now sold for more than 6 yuan and 1 kg, and two catties of peanuts can not squeeze a catty of peanut oil at all. How can 10 yuan/kg of peanut oil be squeezed out? Aunt Zhang, who sells peanuts in the Central Bank of Henan, revealed the "insider": 10 yuan a kilogram of peanut oil must be mixed with inferior rapeseed oil or even gutter oil, otherwise the shop will lose money. "After adding flavors, the color of the sewer oil is very close to peanut oil, and there is no smell, and it can't be identified in peanut oil."

In addition to mixing ditch oil, oil shop owners will also make wrong ideas on peanut raw materials. According to Aunt Zhang, there are many grades of peanuts. The best quality peanuts are suitable for oil extraction. But some shopkeepers, in order to reduce costs, will buy musty peanuts to extract oil, because the price is cheap, and such pressed peanut oil aflatoxin is very easy to exceed the standard.

In an oil shop in the cold water pit market, the shopkeeper said that he used high-quality peanut oil and that aflatoxin would not exceed the standard. However, the reporter found that the raw materials of peanuts pressed by oil were directly stacked on the wet floor of the shop, and many peanuts had obvious signs of mildew. When the reporter further asked whether the mildewed peanut oil would produce toxins and whether the crushed peanut oil was qualified, the shopkeeper changed his name to say that there was a standard for aflatoxin content in peanut oil. Most peanuts were good and there was no need to be so critical.

Aflatoxin perarsenic

Aflatoxin is a metabolite produced by Aspergillus flavus and Aspergillus parasiticus. When the grain is not dried in time and stored improperly, it is easy to be contaminated by Aspergillus flavus or parasitic Aspergillus to produce such toxins. To be exact, aflatoxins are a group of compounds with similar chemical structures. It includes B1, B2, G 1, G 2, M 1 and other toxins and toxic alcohols. B1 was the most toxic.

According to experts, aflatoxin is one of the strongest chemical carcinogens found at present, and its toxicity is about 68 times that of arsenic. Aflatoxin is easily accumulated in the liver after long-term consumption of food containing aflatoxin, which damages the liver and causes liver cancer and other diseases. In our daily food, aflatoxin hides in many places. Mildewed peanuts, corn, rice, wheat, legumes, nuts and so on may contain aflatoxin, so we should carefully screen the food before eating.

Testing

Aflatoxin in 7 samples of crude oil exceeded the standard

Nandu reporters randomly sampled 7 samples of crushed peanut oil from Huizhou local peanut oil workshop for inspection. The results of the detection report issued by Guangzhou Analytical and Testing Center on October 26 were astonishing: all 7 samples of aflatoxin B 1 exceeded the standard, and the content of aflatoxin B 1 reached 298 micrograms, 13.9 micrograms, 47 micrograms, 322 micrograms, 453 micrograms, 596 micrograms, 130 micrograms and 152 micrograms respectively. At present, the national standard for aflatoxin B 1 content in edible peanut oil should not exceed 20 micrograms/kg. The rate of exceeding the standard reached 100%. One sample from the wheat market in Huicheng District contained 596 micrograms of aflatoxin B 1, which exceeded the standard by 28.8 times.
