US 4,806,376 A · Process for producing a taste-enriching seasoning from beer yeast

Abstract

A process for producing a taste-enriching seasoning or a food possessing augmented richness in taste, which comprises preparing an extract of beer yeast by first extracting an aqueous suspension of beer yeast cells under conditions where no substantial decomposition of the cells occurs; subjecting the suspension to a solid-liquid separation and sterilization to produce a liquid component. The pH is adjusted to about 2-4 before the sterilization. The liquid components is then condensed and neutralized to a pH of about 4.5-7 and the beer yeast extract is added to a seasoning or food containing glutamic acid or salts of glutamic acid and nucleic acid flavoring agents. The beer yeast extract may be optionally dried to a power.

A process for producing a taste-enriching or a food possessing augmented richness in taste, which comprises the steps of:

(i) preparing an extract of beer yeast, said beer yeast being obtained as a by-product in the production of beer, said preparing step comprising the steps of:
(a) extracting an aqueous suspension of beer yeast cells with water under conditions wherein no substantial decomposition of said cells takes place,
(b) separating the solid and liquid components of said suspension,
(c) sterilizing said liquid component,
(d) adjusting the pH of said liquid component to about 2-4, wherein said adjusting step occurs before said sterilizing step, and
(e) condensing and neutralizing said sterilized liquid component to a pH of about 4.5-7.0 to obtain said extract of beer yeast;
and
(ii) adding said extract of beer yeast to a seasoning or food containing at least one flavoring agent selected from the group consisting of glutamic acid, salts of glutamic acid and nucleic acid flavoring agents.
