The invention relates to a method for the preparation of a yeast by degrading yeast with enzymes having RNA degrading activity leading to 5 min -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 min -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.
