"Today I went to the market and bought a bag of peanuts. Ready to take it to the oil mill and let it be pressed into peanut oil. ”
"I don't think the oil squeezed by those small workshops is safe, so I might as well buy some brand oil. ”
"The oil I squeeze myself is definitely free of additives, and the meals made from this oil are more fragrant and safer. ”
In the process of stir-frying, edible oil is an indispensable and important ingredient. At present, there are many types of edible oil available in the market, but there are still many families who like to eat self-pressed oil.
I think that this kind of oil is more mellow and can make more delicious meals, and the most important thing is that the oil you squeeze yourself is safer, so you don't have to worry about gutter oil. Is this really the case?
In response to this phenomenon, some experts have suggested that self-extraction is not necessarily safe, especially in small oil mills, where the environmental hygiene is very poor.
In particular, the oil extraction machine is not cleaned all year round, and a large amount of oil remains on it. Over time, the remaining oil deteriorates, and if the oil is squeezed with this machine, there is a risk that the new oil will be contaminated.
In fact, many people choose self-pressed oil materials are easy to mold, if you use moldy peanuts or corn to extract oil, the squeezed oil contains some carcinogenic substances, such as aflatoxin.
This toxin not only increases the risk of liver disease, but may also cause liver cancer. And most of the presses used in small workshops are very simple.
Some harmful substances are not removed, and the raw materials cannot be carefully selected. In such a situation, the oil is not safe, and it may even be contaminated.
When it comes to the issue of edible oil, I believe most people think of gutter oil. Especially when various food problems frequently appear, gutter oil has also become a topic of concern.
This kind of oil actually comes from some waste edible oil such as gutter or 10,000-year-old oil, which is sold in the market after simple processing.
There are some unscrupulous traders who often collect oil from the sewers of large hotels and sell it by simply processing it. Although the remediation of waste oil is getting stronger and stronger, due to the relatively high profit of waste oil, there are still some criminals who use waste oil for reprocessing.
If you consume gutter oil for a long time, it may cause cancer. Therefore, when choosing edible oil, we must be careful to screen. In addition to buying high-quality cooking oil, you also need to be careful not to use the following oils when stir-frying and cooking.
For example, reused oil. This is especially the case in restaurants, that is to say, after putting some oil in the oil pan and repeatedly frying, this reused oil will release a large number of harmful substances, which is a great safety hazard.
In addition to restaurants, some families often have the habit of feeling that the oil is thrown away after frying food, but unfortunately they will continue to fry or stir-fry.
There are a lot of harmful substances in this oil that is repeatedly fried, and long-term use will definitely cause negative effects on the body. There are also many precautions in the process of edible oil preservation.
For example, improper storage may lead to the deterioration of cooking oil, turning cooking oil into deadly oil. At present, most families choose vegetable oils such as canola oil or peanut oil, which usually have a certain shelf life.
If the lid of the cooking oil is opened for a long time, it will cause the cooking oil to deteriorate. For example, if the cooking oil is switched on and off for more than three months, the oxidative rancidity in it will increase, and this oil cannot be eaten.
Cooking oil that has been opened for a long time will cause oxidation and accelerate the deterioration of the oil. If you want to be healthy, you must stay away from these cooking oils that have gone bad.
In addition, it is important to stay away from hydrogenated vegetable oil in daily life, which is a carcinogen and its harm is comparable to that of gutter oil.
