Among vegetable edible oils, palm oil has a very high oil yield and is also the cheapest. The soybean oil extracted from soybeans is almost a by-product of the soybean meal production process. Processing companies mainly make money by selling soybean meal, and the profits from consuming soybean oil are not that high. The soybean oil blended oil sold on the market is based on extracted soybean oil, and usually some palm oil is added to reduce the cost. Even if it only sells for 70-80 yuan a barrel of 5 liters, there is still a profit.
If you grow rapeseed at home, you can sell it directly for 2 yuan per catty. If oil is used, a pound of rapeseed yields between 4 liang and 4 liang and 5 liang of oil. If the rapeseed cake is not wanted, the processing fee will be waived for the processing party. In addition, the processing party will pay the price difference of 2 cents per catty (according to the weight of rapeseed) to the customer. If you want rapeseed cake. The processing fee is 5 cents per catty, but the rapeseed cake itself can be sold for 1.5 yuan per catty. After all, pure pressed rapeseed oil is much cheaper than buying soybean oil from arowana or something like that.
A large part of large cooking oil companies directly import soybean crude oil (genetically modified) from abroad, and then refine and remove impurities into finished cooking oil, thereby obtaining differential profits without the need for pressing, saving a lot of equipment, factory space, and low investment. Quick results. In addition, even if soybean raw materials are used for processing, there is now a leaching process, which does not require squeezing. That is, soaking soybeans in gasoline, dissolving the soybean oil and heating the gasoline leachate. The gasoline volatilizes and is recycled for recycling. The oil yield of the leaching method is higher than that of pressing. The degreased soybeans Then make soy products such as soy sauce tofu, etc., and also use it as feed fertilizer.
Ten pounds of soybeans should produce 3-3 to 3.5 pounds of oil, two and a half to three pounds of rapeseed should produce one pound of oil, two pounds of sesame seeds should produce a little more than one pound of oil. In our hometown, vegetables The seeds, tea seeds and camellia oleifera seeds are all processed by us in the oil pressing plant, so we know the oil yield.
Several common misunderstandings about genetically modified soybeans:
First, it is no exaggeration to say that 98% of the soybean oil you can buy is made from genetically modified soybeans and is produced domestically. Non-GMO soybeans are all used to make soy products, and some are exported. Very few are used to press soybean oil, because the oil yield is low, and the price of non-GMO soybeans is much more expensive than imported genetically modified soybeans. Pressing soybean oil is not worth it. There are also fewer people.
Second, the state stipulates that genetically modified soybeans cannot be eaten directly and can only be used for oil extraction and feed (that is, soybean meal after oil extraction), so you cannot buy retail genetically modified soybeans in the world. Soybeans, there is no need to worry about buying genetically modified soybeans.
Third, the genetically modified components of genetically modified soybeans are in the protein. Since the extracted oil does not contain soybean protein, genetically modified soybean oil does not contain genetically modified components.
Fourth, who says Americans don’t eat genetically modified soybean oil? The United States produces 105 million to 123 million tons of genetically modified soybeans every year, and exports about 54 million tons every year. Has more than half of the other soybeans been dumped? Like China, the United States does not allow genetically modified soybeans to be directly made into soy products for consumption, but they also eat genetically modified soybean oil, and soybean meal is used as feed for livestock.
Domestic soybeans are pressed to extract oil, while genetically modified soybeans are extracted from oil, that is, soaked in kerosene. The oil yield of genetically modified soybeans is 10% higher than that of domestic soybean oil, and the price is also much cheaper. Of course oil is cheap! But I don’t eat soybean oil. I haven’t bought soybean oil since I learned about GMOs in 2003, and I won’t buy blended oils when I see them.
The soybean oil sold in supermarkets and grain and oil stores is definitely not authentic soybean oil. Everyone knows the oil yield and soybean price, the factory processing equipment wages and other costs, transportation fees, the profits of supermarket grain and oil stores, packaging Wait, after all this calculation, can I buy a barrel of oil for 40 yuan for 5L and 0.00 points for 25L?
The oil yield of domestic soybeans does not exceed 13%, while the oil yield of imported genetically modified soybeans is 24%. The oil is chemically leached and then the chemical materials added are removed during the extraction. This kind of oil is firstly genetically modified soybean oil, and secondly it contains chemical residues. When purchasing non-GMO soybean raw materials, oil companies will appropriately purchase some GMOs. Is it conceivable why? Nowadays, it is indeed difficult to differentiate between refined oil products and non-conventional units. Is this an apology for bullying? There are currently two basic ways to obtain oil, squeezing or leaching. Squeezing is more intuitive. Everyone who is older knows that leaching contains useful chemical components and leaves residues. It is euphemistically called refining.
There is almost no difference in nutrition between genetically modified and non-genetically modified foods, and there is no difference in taste. You can try it yourself. Find three chefs, each providing two identical bottles of oil, one containing genetically modified and non-genetically modified oils. But don’t tell the chef which one is non-GMO and which one is GMO. Then let the chef and stir-fry five dishes each use two types of oil, and then find 50 people to try them to ensure that no one can tell which one is non-GMO and which one is GMO.
Whether it is American soybeans or South American soybeans, our country imports genetically modified soybeans with very good quality, cheap price and high oil yield. These soybeans are in directional circulation, such as Yihai Kerry and COFCO. These large companies squeeze a large amount of imported soybeans every year, and ordinary consumers cannot buy imported soybeans. The products after soybean crushing are soybean oil and soybean meal, so the price of soybean oil does not only depend on the price of soybeans. For example, if the price of live pigs increases, the soybean meal shipped from the factory will be more expensive, and the soybean oil will be relatively cheaper.
On the contrary, if the price of live pigs falls, it will increase oil and suppress meal.
Compared with imported soybeans, Northeastern soybeans have low yields, low oil yields, and high prices. They can only meet 20% of domestic demand, and the remaining 80% need to be imported. The oil yield rate of soybean pressing is above 15%, and can reach 20%. If the leaching method is used, the oil yield rate will be even higher. Most edible oil manufacturers buy futures soybeans, which are in large quantities and at relatively low prices. The general price of 5 liters of genetically modified soybean oil in supermarkets is between 39 and 49 yuan, while non-genetically modified soybean oil is between 59 and 79 yuan. Because soybean oil has a beany smell, ordinary families rarely eat it, and most of it is supplied to catering institutions. Several well-known brands rarely put soybean oil on the shelves, and the varieties are small.
Each acre of land can produce 200 to 250 kilograms of soybeans, with an oil yield of about 13%. An average person consumes 50 kilograms per year, and each person needs 1 acre of land to grow soybeans and chickens. Feed for ducks and pigs requires land, so there is less land in the south, which is not suitable for building big cities. The land in the south can only be supplied by the rural areas. The urban population in the south can only rely on imports to survive on whatever they eat and drink, plus rice from the northeast. , corn has been shipped to the Yangtze River Delta and Pearl River Delta for months at Jinzhou Port in Liaoning.
Nowadays, most oils are extracted from French oils, and very few are actually pressed. The process method is marked on the oil drum. Oil is actually a by-product of oil mills, mainly a large amount of soybean cake and soybean meal. These soybean meal are an important component of various feeds and the price is considerable. Because the waste left over from oil extraction can still be sold to farms, the price is not very cheap, and now blended oil and soybean oil are basically genetically modified beans. Genetically modified soybeans have high yields and are resistant to pests and disasters. In terms of cost, they are not Very high.
Nowadays, soybean oil is soaked with chemicals to produce oil, and the oil production rate is high. The oil-extracted bean dregs are processed into bean cakes (similar to bean cakes), which are used as raw materials for pig and chicken feed. The price is very high, higher than the price of soybeans. Soybean cakes can basically recoup their costs, and soybean oil is the manufacturer's profit.
Another important reason why soybean oil is cheap is that the by-product of soybean oil extraction is soybean meal, which is an important raw material for feed production and can also be sold at the same price as soybeans, such as peanuts, sesame seeds, sunflower seeds, etc. Although the oil yield is higher than that of soybeans, the by-products are basically used as fertilizers and have low value. Therefore, soybean oil is cheaper in supermarkets. This is the main reason.
Oil labeled as non-GMO is not necessarily non-GMO. The oil yield of non-GMO soybeans is low, and if oil mills do not harvest it, farmers will grow less and the price will be higher. Typing those few words more is to sell more money. Nowadays, oil is extracted by leaching method. Try to buy oil with light color. No matter what kind of oil, it has been decolorized and deacidified, so there will be less residual substances that are harmful to the body. Thermal stability is also better.
There are by-products after soybean oil is pressed or leached. Genetically modified soybeans generally have an oil yield of up to 18%, and there is also soybean meal, which can be used as feed and brewed soy sauce. This can be sold. Yes, the oil scraps can be made into soap granules, soybean meal can also be extracted into protein powder, etc. Soybeans can be extracted for oil and can produce many by-products. These are the values ??produced by soybeans. Don’t just count the price of the oil.
