Dude, who told you that? Soybean oil is so expensive? If the extraction cost of soybean oil is 1.9 yuan, the oil yield of imported transgenic soybeans is higher than that of domestic soybeans. If you press oil with a machine in a small workshop, you will get less oil. Generally around 13%. There is a secret that you may not know. That is, after squeezing soybean oil, the weight of soybean cake will not be reduced by steam. The price of bean cake is generally around 1.5 to 1.7. If calculated by 100 kg soybean, about 13 kg soybean oil can be squeezed out. More than 90 kilograms of bean cakes.
