Due to the vast territory of our country and different customs of products in different places, there are great differences in the treatment of edible oils and fats. Many places in the south like to eat rapeseed oil, while most northerners like to eat soybean oil or peanut oil.
Rapeseed oil, which we often say, is generally rapeseed press oil. The quality of mustard rapeseed oil is better than rapeseed oil, and there is no grassy smell of rapeseed oil, so the price is higher than rapeseed oil.
The price of rapeseed oil on the market is quite different from that of supermarkets. Will there be fakes? First, regular supermarket brand rapeseed oil will not be fake, cheap mainly because:
At present, the price of rapeseed oil in supermarkets is high or low. Generally, the price per catty is about 10 yuan, and the price of the cheaper one is more than that of 5 yuan. In addition to well-known brands, the raw materials used in cheap rapeseed oil are also very different. Generally, many cheap rapeseed oil will be labeled as genetically modified rapeseed, so rapeseed is imported from abroad. Because of the low purchase cost and the low price of natural refined oil, there are few consumers who like to buy this genetically modified oil in the market now.
Generally, the purchase price of rapeseed with 3 yuan is about 1 kg, because the fullness and dry humidity of rapeseed are different, so the oil yield will be different, but basically 3 kg of rapeseed can produce about 1 kg of oil. However, all the oil can't be extracted from rapeseed after pressing, so the remaining rapeseed can still get oil by leaching. The quality of pressed oil is definitely better than that of extracted oil, so the price of extracted oil will naturally be low. According to whether the process marked on the rapeseed oil label is squeezing or leaching, it can be seen that generally cheap rapeseed oil is leached.
Rapeseed contains erucic acid. When buying rapeseed oil, the lower the erucic acid content, the better the oil quality, while the rapeseed oil with erucic acid content ≤5 is of average quality, so the price is cheaper.
The second is rapeseed oil sold in the market.
Rapeseed oil looks like 3 kg rapeseed yield 1 kg oil. It is a loss to sell only 8 yuan. However, rapeseed cake, a by-product of oil pressing, is expensive because of its great use. Generally, rapeseed cakes can be sold to about a catty in 3.5 yuan, so that the cost can be recovered by selling rapeseed oil to a catty in 8 yuan, and rapeseed cakes are all pure profits.
Although the rapeseed oil sold in the market is also true, the impurities in all aspects processed by small workshops are relatively high, and if the filtration and purification level is not enough, the color of this rapeseed oil is dim and the oil smoke is too large during cooking. Although it is real rapeseed oil, it may not be as good as the rapeseed oil in the supermarket.
Third, buy rapeseed oil.
Try to buy products trusted by big brands: the safety of edible oil is very important. The production technology of big brands and well-known manufacturers is advanced and subject to various supervision, so the quality is trustworthy.
Don't buy genetically modified rapeseed oil with high erucic acid content: even if the price is cheap, try not to buy genetically modified rapeseed oil because its raw materials are in doubt. Erucic acid content is an important index to test the quality of rapeseed oil. The lower the erucic acid content, the better the quality. You can buy it according to the label.
Although the rapeseed oil sold in supermarkets in 5 yuan is genuine rapeseed oil, the source and quality of raw materials will be defective. For the safety and protection of edible oil, I think it will be more reassuring to buy brand rapeseed oil around 9 yuan in the supermarket. Rapeseed oil sold in the market is in doubt because of safety and health inspection, so it is better not to buy it. Some things are not handled in the indigenous way.
