Soybean is an important oil resource as well as protein resource. Soy oil protein accounts for 13% of the world's total protein resources. The protein content of defatted soybean meal is 42 ~ 50%. High temperature soybean meal from soybean oil production is mainly used as feed, which is the main raw material of high quality protein in animal full-price compound feed. Soybean meal accounts for 62% of the world's feed meal and has become a decisive factor in the development of the world's animal feed market. Low temperature soybean meal from soybean oil production is mainly used to produce a variety of edible soybean protein products, such as soybean protein isolate, soybean protein concentrate, soybean tissue protein, soybean protein powder, etc. These soybean protein products are used as ingredients in meat products, high-protein drinks and other foods.
The general soybean protein content is about 36% (in order to ensure the protein content of protein isolate is up to the standard, protein beans are generally selected for the production of protein isolate, with protein in 39-40%), and the protein content of food-grade soybean meal is about 45%. Under the general domestic production conditions, 1 ton of domestic soybean can produce 0.16 ton of soybean oil and 0.785 ton of soybean meal. One ton of soybean meal can produce 0.35 ton of soybean protein isolate. In other words, it takes 3.64 tons of soybeans or 2.85 tons of soybean meal to produce 1 ton of soy protein isolate. The processing cost is about 3000 yuan per ton.
Raw materials for domestic soybean protein isolated non-gmo soybeans, but China's soybean's far more than 80%, therefore China's soybean prices without independent voice market anticipation of soybean protein isolated protein should not only consider the supply and demand of the industry, the domestic soybean planting area and yield production, also need to consider the international soybean prices (imports).
