Problems solved by technology
The former has a better detoxification effect, which can save equipment and energy, but the biggest disadvantage is the residue of chemical substances, inconvenient operation, and high cost; the latter includes enzyme preparation treatment and microbial fermentation, which can effectively reduce anti-nutritional factors in soybean meal and increase protein content. Bioconversion rate, the disadvantage of which is high technical requirements and high processing costs

Embodiment Construction
[0015] The present invention will be further described below in combination with specific embodiments and accompanying drawings.
[0016] like figure 1 Shown, a kind of production method of the soybean protein that improves feed utilization rate, comprises the steps:
[0017] a. Drying and cooling the soybeans at first, wherein the moisture content of the soybeans is less than 13%;
[0018] b. Crushing and shelling soybeans, and sieving and shelling;
[0019] c. Directly expand and extrude the shelled soybeans to obtain natural soybean oil and low-antigen soybean meal.

The invention discloses a production method of soybean protein for improving the utilization ratio of feed, which is used for separating natural soybean oil and antigen-free soy protein by puffing and extruding soybeans in a dry mode. The soybean protein produced by the invention has the characteristics of low antigen, high bioavailability, simple and reliable technology, low cost and the like.
Description
technical field [0001] The invention relates to the technical field of feed, in particular to a production method of soybean protein which improves the utilization rate of feed. Background technique [0002] Soybean and its processing by-products are the most widely used plant-based feed protein raw materials at home and abroad. Its protein content is high, and except for sulfur-containing amino acids, other amino acids are relatively balanced. Soybean processing by-products——soybean cake and meal, as a kind of good plant-based feed protein raw materials, can generally reach 20-30% in the diets of livestock, poultry and aquatic animals. However, due to the soybean meal produced by conventional soybean processing methods, there are some anti-nutritional factors that affect nutrient digestion and the physiological health of livestock and poultry, such as trypsin inhibitors, lectins, flatulence factors, anti-vitamin factors and antigenic proteins. Not only its nutritional value...
