What do people eat every day? Is it rice? Is it meat? Or vegetables? In fact, it is not, it is an edible oil that is easily overlooked. Oil is used as long as cooking, and the safety of oil is also a concern of everyone. However, in recent years, there have been constant news reports that there are frequent problems in the sampling inspection of edible oil, which also makes people worry about whether they will buy these problematic edible oils.
Sampling inspection of edible oil, carcinogens exceeded 20 times the standard
There are several food safety sampling inspections every year. Among the edible oils sampled in Guangxi, it was found that benzopyrene and acid values in 2 batches of edible oils exceeded the standard, and there was another batch of edible oils. Benzopyrene is more than 20 times higher than the standard, which is a strong carcinogen that may bring the risk of cancer to the human body.
And this is not the case.
In March 2021, Hunan Market Supervision Bureau announced 12 batches of unqualified edible oil, and 2 batches contained benzene. And pyrene exceeded the standard; Heilongjiang Market Supervision Bureau found 6 batches of substandard edible oil. Eating these unqualified edible oils is likely to pose a threat to people’s health.
The amount of benzopyrene in edible oil exceeds the standard, how harmful is it?
Benzopyrene is a polycyclic aromatic hydrocarbon compound, which may produce toxins during the high temperature pressing of oil and fat. If people often cook at high temperature by frying Food may also produce benzopyrene in the case of high temperature and burning. It will enter the human body with the respiratory tract and digestive tract, and cause extensive damage to people’s health.
It is also listed as a class I carcinogen by WHO, along with aflatoxin and alcohol, which can cause health hazards. Increases the risk of many types of cancer and threatens health.
Unqualified edible oil may have two problems besides benzopyrene exceeding the standard.
Question 1: Excessive acid value
When the technology used for edible oil is not in place, or when the storage environment is not up to standard, it may lead to the problem of rancidity of the oil. There may be more aldehydes and ketones in the oil with excessive acid value. Eating such oil will increase the burden on the stomach and liver, and it is more likely to hurt the body.
Question 2: Excessive Aflatoxin
The reason for this is mostly related to the raw materials used in edible oil. When there are problems such as mildew and deterioration of the oil, the aflatoxin contained in it will also enter the oil with the process of oil extraction. Moreover, this is a very strong carcinogen. As long as 1 mg is ingested, it may induce canceration, induce continuous liver damage, and finally bring about liver cancer.
For people, edible oil is a food that is used every day. If it is found to be abnormal, it must be replaced in time at home. oil, so as not to affect health.
After sampling the edible oil, many oils with excessive carcinogens were found. People should keep their eyes open. And you should also carefully screen your own cooking oil to avoid being targeted.
If there are 4 kinds of cooking oils in the kitchen, don’t eat them
First of all, Hazelnut-flavored cooking oilprobably rancid
Many people think that cooking oil is fine as long as the lid is closed. Often placed next to the stove, the high temperature continuously affects the cooking oil. In this case, it is more likely to cause rancidity of the edible oil. At this time, the edible oil may smell some salsa, and this kind of oil is not suitable for continued consumption.
The second isOil that is more than half a year after opening, it is not recommended to continue to eat strong>
When buying oil, large bottles of oil are often more affordable. In order to save some money, many people are more willing to buy oil in large bottles. But people overlook a problem, edible oil also has a shelf life after opening. If it has been opened for more than half a year and has not been properly preserved, it is likely to cause more problems of rancidity and deterioration, and the safety of edible oil will be greatly reduced. If your family also has this kind of cooking oil that has been opened for more than half a year, it is not recommended that you continue to eat it. Next time, try to buy oil in small bottles as much as possible.
The third type isself-pressing oil from small rural workshops
Due to the influence of production process and environmental factors, the small workshops of self-extracting oil hardly have the conditions for sterilization and disinfection, and the raw materials used may also contain more aflatoxin. The problem of aflatoxin infection is more likely to occur in this self-pressed oil, and it is also more likely to cause liver cell damage to the human body after consumption.
In addition, small workshops in rural areas cannot fully clean up the oil extraction equipment, and some oil remains in the gaps of the equipment, which may also deteriorate, In the case of mold, the oil extracted will also be more likely to be contaminated.
The last one isthe oil left over after frying the food
Think about saving. Many people keep the oil in the croquettes and use them later when they cook next time, which can also avoid waste. However, this repeatedly used oil is more likely to generate benzopyrene with high temperature heating and food frying. During the cooking process and when eating, benzopyrene is brought into the human body, which will increase the cancerous changes in disguised form. Risk, threat to health.
If you usually pay less attention to the cooking oil at home, I suggest you go to see if there are any of these 4 oils. If there is, replace it in time, so as not to contaminate a pot of good dishes because of the cooking oil, which will pose a threat to health.
