Abstract
The invention relates to a method for the preparation of a yeast by degrading yeast with enzymes having RNA degrading activity leading to 5'-ribonucleotides, wherein oxidizing conditions are maintained during the enzymatic degradation. Preferably the proteolytic degradation is carried out under anaerobic conditions, and the RNA degrading activity leading to 5'-ribonucleotides under oxidizing conditions, such as an oxygen saturated incubation medium. The invention also relates to the yeast extract obtained, to the use of the yeast extract and to a flavouring and a food composition comprising it.
Claims13
A method for the preparation of a yeast extract by degrading yeast with enzymes having RNA degrading activity yielding to 5'-ribonucleotides, wherein oxidizing conditions are maintained during the enzymatic degradation and the oxidizing conditions comprise an oxygen concentration of about 0.1 to 30 mg/l of aqueous yeast-containing medium.
The method as claimed in claim wherein enzymatically degraded yeast is subjected to fermentation with micro-organisms.
Yeast extract obtained by degrading yeast with enzymes having RNA degrading activity leading to 5'-ribonucleotides wherein oxidizing conditions are maintained during the enzymatic degradation.
