Process of producing soybean and/or soy protein products

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 wit...

Beschreibung
Zusammenfassung:	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 DEG C. to 95 DEG 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).
