Since 1995, the perennial planting area is100000 mu, and the annual output of rapeseed is nearly1000000 tons, accounting for 40% ~ 45% of the total output of oil crops (excluding soybeans); At the same time, it also produces about 6 million tons of rapeseed cakes.

The protein content of the cake is as high as 40%. The amino acid composition of rapeseed protein is reasonable, and the lysine content is equivalent to that of soybean, while the sulfur-containing amino acids such as lysine and methionine are higher than that of soybean protein, which is the largest source of high-quality feed protein to be developed and utilized in China.
