A catty of soybeans in normal circumstances can be how much soybean oil?

From the current varieties of soybeans, soybeans generally in the 15-22% oil rate in this area, that is to say, a catty of soybeans can be obtained one or two five to two two of the soybean oil, the rate to see than rape, sesame, peanuts, the oil rate is much lower. Soybean oil rate with soybean varieties, origin, and extraction process has a great relationship.

This year by the Mudanjiang Academy of Agricultural Sciences cultivated by the high oil soybean "Dongsheng 79" average fat oil content reached 24.16%, compared with 17% of the ordinary soybean is really much higher, and this oil content is even higher than the imported genetically modified soybeans and 2 percentage points, and since 1966, Heilongjiang has been Since 1966, Heilongjiang has not been able to break through the 24% ratio among the varieties that have been validated. It is also a breakthrough in the history of soybean breeding in China. p>1, origin

Our country, the vast north-south climate difference is also great, the northern varieties of soybean in the south even if they can bear fruit, the quality will also decline a lot. And like the United States, this side of the climate is more suitable for the growth of soybeans, under the same circumstances, the United States of America's soybean oil content can be higher than the oil content of our soybeans by one percentage point.

2, oil extraction process

Currently, oil refining is taken by the physical press and leaching two main ways, physical press method is a kind of pressure in the soybean will be pressed out of the oil in a way, which is the most traditional way of oil refining. This is the most traditional way of refining oil. However, this way of refining oil leaching rate is low, compared with leaching, can be one or two percentage points lower.

Today, some refineries commonly use leaching, using edible solvents to extract oil from the raw material in a way, which is also recognized internationally as the most advanced extraction process, the oil extraction rate is very high.
