Let's talk about it first It's just cold pressing oil. ● Peanut oil is the most fragrant. If it's cold pressed, it's because peanuts are fried first and then pressed for oil. The oil mill is full of the smell of cooked peanuts, which can be smelled far away.
● Rapeseed oil is the vegetable oil that farmers eat the most, because rape can be planted in a large area, leaving enough for themselves to eat and sell, which is the main crop.
● The consumption of corn oil is not very common, mainly because the oil yield of corn is not high, about 5%, so it is rarely extracted from corn alone. However, the processing value of corn is great. For example, when processing corn grits and corn flour, the corn germ will be separated and then the oil will be squeezed. The oil yield is close to that of peanuts, up to 28%, and the nutrient content is high.
● Sunflower seed oil has developed greatly in recent years and is also a high-quality edible oil.
Besides, it's not good ● The biggest problem with peanut oil is that peanuts are prone to mildew and deterioration. Unlike other grains, just pick out the moldy ones and throw them away. Peanut mildew will produce aflatoxin, which can't be thrown clean. For example, there are some bad rice in 10 kg of peanuts, and the squeezed oil is not qualified. Unless the product is made by a big factory, the oil squeezed out is filtered in a standardized way and there is no aflatoxin in it. The oil squeezed by other small workshops is not qualified. The key is to filter, even if it smells good.
● Rapeseed oil, corn oil and sunflower oil are all genetically modified. Although the management is strict and people are not allowed to enter the scope of use, no one dares to say clearly what is right and what is not.
● The refining method is also worth mentioning. The refined oil is very clean, only oil, genetically modified ingredients, aflatoxin, pesticide residues, heavy metal herbicides and all other harmful substances are gone. But there are flotation agent residues, and there is no smell of vegetable oil.
Finally, how to choose edible oil. ● First, choose the cold-pressed peanut oil from big factories and brands, which has all the nutritional taste of peanuts, no aflatoxin residue, and peanuts have not been genetically modified, that is, the price is more expensive than other similar products.
Second, select local products and traditional tea oil. This oil surpasses the world's first olive oil and the best vegetable oil in terms of nutrition and taste. It's fake and adulterated. Pay attention to screening when you buy it. There are also traditional sesame oil, such as Henan sesame oil, which is unique and fragrant. It is used for seasoning and is reluctant to fry.
● Third, choose refined oil. Compared with peanut oil and rapeseed oil in small workshops, the safety index can be assured, that's all, and the taste is not good.
