Abstract: The present invention relates to a method for obtaining yeast proteins comprising the following steps: a) providing a yeast cream; b) exposing this yeast cream to a thermal plasmolysis at a temperature between 70 and 95° C. for a time of between 30 seconds and 4 hours; c) subjecting the whole to the activity of at least one ribonuclease and a glucanase, sequentially or simultaneously, at a temperature between 40 and 65° C. for a period of between 8 and 24 hours; and d) separating the insoluble fraction from the soluble fraction; wherein the insoluble fraction collected in step d) is taste-free, has a nucleotide content less than 3% and a true protein content of at least 72%.

Abstract: A novel yeast extract having from 25 to 55 wt % 5?-ribonucleotides, including 5 to 20 wt % adenosine 5?-monophosphate (5?-AMP) and 5 to 20 wt % guanosine 5?-monophosphate (5?-GMP) in a 5?-AMP/5?-GMP ratio ranging from 0.85 to 1.25, the weight percentages being expressed in relation to the dry weight of the yeast extract. Also a process of using such an extract for the masking of bitter and sour tastes and of undesirable sweetener, protein and metallic notes in a product.

Abstract: The present invention relates to the use of a yeast protein extract to stabilise the haze or cloudiness of a drink, particularly beer and preferably white beer.

Abstract: The present invention relates to the use of a yeast extract including at least 10 wt % of nucleic acids, preferably at least 15 wt %, and more preferably 30 to 95 wt %, relative to the total weight of said extract, said nucleic acids being formed from fragments of ribonucleic acid (RNA), for clarifying musts and liquids, in particular wines and teas.
