Patent ID: 8153174

Claim:
A fermented protein product derived from Saccharomyces cerevisiae or spent brewer's yeast and one or more plant proteinaceous pulse sources prepared by a method comprising: (i) mixing as the sole yeast live Saccharomyces cerevisiae or spent brewer's yeast with one or more plant proteinaceous pulse sources in a dry matter ratio of from about 1:2 to 1:100; (ii) fermenting the yeast/pulse source mixture resulting from step (i) under conditions where the water content does not exceed 80%, for 1-12 hours at a temperature of about 25-60° C., under anaerobic conditions; and (iii) incubating the fermented mixture resulting from step (ii) for 0.5-240 minutes at a temperature of about 70-150° C. in a closed system, the incubation time being sufficient to kill all microorganisms and to inactivate remaining anti-nutritional factors, wherein a short incubation time is used at high incubation temperatures and a long incubation time is used at low incubation temperatures; wherein said fermented protein product has a protein content of about 25-80% by weight on a dry matter basis, wherein about 1-35% of the protein content is derived from yeast and about 65-99% of the protein content is derived from proteinaceous pulse parts, said fermented protein product has a glyceride content of no more than 30% by weight on a dry matter basis.
