Title: Discuss on Preparation of Soybean Protein Concentrate by Alcohol
Abstract: A continuous solvent system was used to produce the soy protein concentrate. The defatted soy flake was submitted to aqueous alcohol extraction twice and the extracted material was desolventized in a single step. The effects of ethanol concentration, extraction temperature and duration, and solvent amount on the properties of soy protein concentrate were studied. By perpendicular experiment design, the optimized processing conditions were found to be: ethanol concentration 75% (v/v), extraction temperature 30℃,duration 60 min,and flake solvent proportion 1∶5. The second extraction condition: ethanol concentration 90%(v/v), extraction temperature 50℃, duration 30 min, and the raw material to solvent ratio was 1∶5.
