Disclosed is a process to produce a composition containing 5’-ribonucleotides comprising: a) Subjecting a yeast to autolysis under conditions at which at least 50% of the RNA remains in a form degradable into 5’-ribonucleotides; b) Subjecting the autolysate to solid/liquid separation and recovering the RNA-containing cell wall fraction and wherein at least 75% of the RNA remains associated with the cell wall fraction; and c) Converting the RNA in the recovered RNA-containing cell wall fraction into 5’- ribonucleotides, whereby the solid/liquid separation in step b) is done at a pH of lower than 3.5 and higher than 1.0. |
