1. Raw Materials: low-temperature soybean flakes ( Soya White Flake ) 2. Products: food grade or feed grade soybean protein concentrate (SPC) 3. Applications 3.1 Food grade SPC is usually used as additives of flour-made food and meat products. It is also applied for production of health care products, which contain about 70 percent protein. 3.2 Feed grade SPC is applied as feed additives in particular, which are put in fodders for baby pigs, aquatic livestock, calves or pets. 4. Process Description In our production line, edible alcohol is used to extract and separate water-soluble components (mainly soluble sugars) from low-temperature soybean flakes. The resulting soybean product will be extruded, smashed, desolventized, dried and superfinely milled, thus obtaining soybean protein concentrate. The whole production process won`t generate water pollution and air pollution, which is environmental friendly.
