Recently the project was completed, and the company gave project members a three-day vacation. While Xiao Li was happy, he suddenly thought of his grandmother who lived alone in the countryside. He took this opportunity to visit the old man.
Grandma was naturally very happy to see her grandson coming back, and she was about to make delicious food to reward her grandson. Xiao Li was not idle either, and helped her grandma cook in the kitchen.
Inadvertently, Xiao Li caught a glimpse of a stainless steel basin next to the stove. It was filled with yellow and some sediment suspended in rural self-extruded oil. Xiao Li claimed to know some health knowledge. He thought that these oils were not nutritious and not healthy, and it was safe to buy them in supermarkets. Is this true?
Is it true that barrel oil in supermarkets is more nutritious than rural self-extruded oil?
Let's take a look at the production process of the two:
Rural self-extruded oil is more nutritious than rural self-extruded oil?
Let's take a look at the production process of the two:
Rural self-extruded oil Most oils are mainly peanut oil and rapeseed oil . The raw materials grown by one are sent to the oil mill after receiving the goods and then the squeezed oil is collected...
Therefore, Rural self-extruded oil are mostly simple and direct. The nutrients in the raw materials will not change much. This is an advantage, but it is also a "disadvantage". While not containing additives, contains relatively single nutrients, only fat or a small amount of vitamins, etc.
and supermarket barrel oil , after regular assembly line production, the pressing efficiency is higher, , but the aroma and taste of the oil may be slightly inferior to . However, most of the barrel oil is blended oil, and other ingredients will be added during the production process, so the nutritional richness of will be higher .
To summarize, rural self-refined oil is better in terms of taste and aroma. However, the nutritional content is relatively single; supermarket barrel oil has a wide variety of nutrients, but the taste is slightly inferior. In fact, as long as the production process is clean and hygienic, and no counterfeit and shoddy products are purchased, it is OK to eat any kind of oil. Change the oil every once in a while, which is a choice that has both taste and nutritional value.
So, rural self-extrusion is not as bad as Xiao Li said, but many netizens have additional concerns: it has been circulating on the Internet that self-extrusion in rural areas causes cancer. Is this statement reliable?
Rural self-extrusion in rural areas causes cancer? Let’s take a look at the experiment done by CCTV. The saying goes,
There are rumors that self-extrusion in self-extrusion causes cancer, which is nothing more than two reasons: the smoke point is too low, and the risk of infection of Aspergillus aflatoxin is high.
First of all, "smoke point" comparison between the two :
refers to the temperature that oil reaches when oil smoke comes out under high temperature burning. Excessive oil fume contains carcinogens such as benzopyrene , and oil with low smoke points for a long time does have a risk of carcinogenicity.
However, in CCTV's " Focus Interview " program, rural self-extruded oil and barrel soybean oil were randomly selected for comparison. The result was that the smoke points of both were between 220 degrees and 240 degrees. According to verification, as long as is the same variety of oil, there is no saying that the smoke point difference is.
Does self-extruded oil contain aflatoxin ?
Aspergillus aflatoxin is also the biggest concern for rural self-extruded oil. Aflatoxin comes from moldy grain raw materials. If spoiled grain is used to squeeze oil, aflatoxin will be found in the oil.
We do not deny that some unscrupulous rural workshops are not detrimental to market control and the use of spoiled grain oil pressing does have a risk of carcinogenicity, but this has nothing to do with rural self-extrusion itself. Just like some supermarkets have bottled oil, there have been scandals about some spoiled products, and it is not advisable to generalize.
Therefore, whether it is self-extruded in rural areas or barreled oil in supermarkets, as long as it can ensure that the raw materials are healthy and do not deteriorate, the production process is qualified and safe, it is that does not have health risks such as carcinogens.In contrast, some other oils are more worthy of our attention.
These three types of "bad oils" are not good for health. You should pay more attention to
The first type: " saliva flavor" edible oil
Friends with rich kitchen experience should have experienced it. When opening a can of unsalted oil, there will be a "slobber smell". In fact, this is the taste emitted by Hydrogenated fat after spoilage . Edible oil with a "slobber-flavored" is equivalent to spoiled edible oil, and there is a risk of aflatoxin, so throw it away quickly.
The second type: Repeated oil
When frying something at home, most of the pot of oil will often be poured over. After using it, it feels a pity to throw it away, so it will be saved and eaten again. If you use oils like
again and again once or twice, it will not be a big problem. However, if you use them repeatedly many times, and even the oil becomes red and black, it means that there are more benzopyrene, heavy metals and other substances produced by the heating of the oil, which will be detrimental to your health. It is better to pour out the oil for for more than 3 times, for the sake of health.
The third type: Artificial oil
For example, margarine, margarine, etc. . One of the major characteristics of margarine oil is that has a high content of trans fatty acid . Too much intake of trans fatty acids will lead to a significant increase in cholesterol , and the risk of cardiovascular disease and hyperlipidemia will also increase. Moreover, the nutrients in artificial oils are not as high as vegetable oils and animal oils.
In some inferior desserts, cheap chocolate and other foods, artificial oil is used more frequently. What we can do is try not to buy it, especially those who already have hypertension, , hyperlipidemia or obesity. No matter how hungry you are, you must keep your mouth under control.
Oils are an indispensable part of the diet. Whether it is rural self-extruded oil or barreled oil, as long as the raw materials are safe and healthy, and the production is transparent and qualified, they can be eaten. Don’t be too prejudiced. Use oil reasonably and eat a healthy diet so that your body can lay a good foundation.
In contrast, some other oils are more worthy of our attention.Reference:
