Meanwhile, by the way, the answer comes from Zhihu. The following is to discuss which is healthier.
China people's edible oil has strong regional characteristics, which is related to the origin of raw materials.
Northeast people eat more soybean oil, but now it is gradually decreasing. First, soybeans are produced in the northeast; Second, the color of soybean oil is dark, which affects the color; The three major soybean oils have high cholesterol content; Fourth, with the formation of healthy eating habits, heavy-flavored soybean oil is decreasing. Finally, soybeans account for the largest proportion of genetically modified gadgets.
Sunflower seed oil, cottonseed oil and tea oil are equivalent.
Peanut oil is the healthiest oil closest to eating habits in the north of the Yangtze River in China. 1) The peanut flavor of pure peanut oil will not mask the taste of dishes. The mellow taste itself will enhance the taste. 2) It belongs to vegetable oil and has low cholesterol. 3) Bright colors do not affect the color of vegetables. 4) Suitable for frying, stewing, boiling and stewing. But peanut oil, which ordinary people could afford, is now too expensive.
Personally, I think blending oil is the product of deception. Focus on the following:
Blended oil was formed in the middle and late 1990s with the transfer of large tank oil/bulk oil to small package oil. (that is, ordinary people go to the village to pump bulk oil, or break it up and sell it in 360 kg iron drums, and then sell it in small packaging products such as 5L in the supermarket. ) The earliest promoters and promoters of blended oil were palm oil and salad oil importers in southeast and Guangdong, because they were far away from the main producing areas of soybean oil and peanut oil and wanted to increase the added value of imported oil products.
The raw material of salad oil is soybean, which is the product of secondary purification. It's decolorized and deodorized-it has no color or taste. The bottom oil and the last bright oil used for frying in restaurants are salad oil (salad oil also has different grades).
The initiator of blending oil pays attention to the concept of "health". Blended oil finally formed a better result than salad oil, cheaper than peanut oil and clearer than cottonseed oil and rapeseed oil-and became a favorite product for everyone. However, there are several buts below! !
The main components of 1 blended oil are peanut oil, salad oil, corn oil, sesame oil and palm oil. The former two are mostly, the latter oil is darker in color, and peanut oil is the most expensive in a single oil. However, the national proportion does not stipulate that a drop of peanut oil is also blended oil, which is also the reason for the large price difference of blended oil in supermarkets.
However, there is no national standard or formulation for blending oil. There is an old saying in China that "oil worries oil ghosts". No instrument can really check whether the blending oil is blended according to the proportion marked on the label, and at most, it can check whether there is any oil. But more or less, the cost difference is huge.
To sum up, those who don't care about money should pay attention to the quality of peanut oil, and white-collar workers who don't cook often should buy blended oil to see which one is pleasing to the eye. No matter how big the brand is, it makes no difference. China's oil products are all from those four or five companies. . .
