Abstract
Soybean and/or soy protein products are prepared by: PA1 (a) contacting a soy protein-containing material with an ethanol-water mixture; PA1 (b) separating the liquid fraction from the suspension of step (a); PA1 (c) dividing the liquid fraction into first and second portions; PA1 (d) diluting the first portion with water to an ethanol concentration of less than 40%; PA1 (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.; PA1 (f) removing volatile materials from said diluted portion and recovering distillation bottoms from said extractive distillation; PA1 (g) subjecting the distillation bottoms to azeotropic distillation and recovering the distilled portion thereof; and PA1 (h) combining said distilled portion with said second portion of step (c) as the feed material for step (a).
