摘要： Soybean and/or soy protein products are prepared by:(a) contacting a soy protein-containing material with an ethanol-water mixture;(b) separating the liquid fraction from the suspension of step (a);(c) dividing the liquid fraction into first and second portions;(d) diluting the first portion with water to an ethanol concentration of less than 40%;(e) subjecting the diluted portion to extractive distillation in a tower at a temperature in the range of 80.degree. C. to 95.degree. C.;(f) removing volatile materials from said diluted portion and recovering distillation bottoms from said extractive distillation;(g) subjecting the distillation bottoms to azeotropic distillation and recovering the distilled portion thereof; and(h) combining said distilled portion with said second portion of step (c) as the feed material for step (a).
