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 15 words
Process according to claim 1, in which the microorganism is S. cerevisiae strain DDSF maltersergaer.
Claim 4
Dependent Claim 15 words
Process according to claim 1, in which the microorganism is S. carlsbergensis strain DGI F216.
Claim 5
Dependent Claim 17 words
Process according to claim 1, in which the microorganism is S. cerevisiae var. ellipsoideus strain BB sauterne.
Claim 6
Dependent Claim 17 words
Process according to claim 1, in which the aqueous solution or dispersion contains 15- 50% dry matter.
Claim 7
Dependent Claim 22 words
Process according to claim 1, in which the aqueous solution or dispersion contains 0.5-20% of water-soluble carbohydrates before the fermentation is initiated.
Claim 8
Dependent Claim 17 words
Process according to claim 6, in which the aqueous solution or dispersion contains 5-15% of water-soluble carbohydrates.
Claim 9
Dependent Claim 15 words
Process according to claim 1, in which the temperature is from 28° to 37° C.
Claim 10
Dependent Claim 16 words
Process according to claim 1, in which the pH is adjusted in the range of 4.5-5.0.
Claim 11
Dependent Claim 32 words
Process according to claim 1, in which the substrate is seeded with sufficient inoculum to reach an initial cell concentration of at least 10 6 -10 8 cells per g of substrate.
Claim 12
Dependent Claim 29 words
Process according to claim 1, in which sterile air is blown through the substrate in amounts of 0.1-2 volumes per volume of substrate per minute during the fermentation period.
