Abstract
Abstract This invention provides a method for removal of all water soluble carbohydrates in the production of plant protein products, including oligosaccharides containing alpha-1,6-galactosidic bonds which are known to cause flatulence in man and animals. In the method an aqueous solution or dispersion of the plant protein material containing 1-60%, and preferably 15-50% of the dry matter is fermented with particular strains of Saccharomyces that have been found to degrade and assimilate flatus-causing carbohydrates. The fermentation is effected at a temperature between 20° and 40° C for from 12 to 48 hours, on which, if desired, the fermented material is dried.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
79 words
Process for removal of water-soluble carbohydrates in the production of plant protein products in which an aqueous solution or dispersion of the carbohydrate-containing material containing 1-60% dry matter is inoculated with a microorganism selected from the genus Saccharomyces and having the ability to degrade and assimilate flatus-causing carbohydrates and fermented for from 12 to 48 hours at a temperature of 20° to 40° C and at a pH of from 4 to 7 to remove substantially all water-soluble carbohydrates.
Claim 2
Dependent Claim
79 words
Process for removal of water-soluble carbohydrates in the production of plant protein products in which an aqueous solution or dispersion of the carbohydrate-containing material containing 1-60% dry matter is inoculated with a microorganism selected from the genus Saccharomyces and having the ability to degrade and assimilate flatus-causing carbohydrates and fermented for from 12 to 48 hours at a temperature of 20° to 40° C and at a pH of from 4 to 7 to remove substantially all water-soluble carbohydrates.
Claim 3
Dependent Claim
