Abstract: The invention provides a process of producing a non-alcoholic beer comprising the steps of: fermenting the wort with live yeast to produce a fermented wort; subjecting the fermented wort to one or more further process steps to produce a non-alcoholic beer; and introducing the non-alcoholic beer in a sealed container; wherein either the fermentation produces a non-alcoholic fermented wort or wherein the fermentation produces an alcoholic fermented wort and alcohol is subsequently removed to produce a non-alcoholic fermented wort or a non-alcoholic beer; and wherein the heated wort, the non-alcoholic fermented wort and/or the non-alcoholic beer is contacted with a hydrophobic silicate-based molecular sieve. Flavour substances contributing to undesirable flavour notes in non-alcoholic beer can be removed effectively during production by contacting wort before or after fermentation with a hydrophobic silicate-based molecular sieve, provided the wort contains virtually no alcohol.

Abstract: A method of producing beer having a tailored flavour profile is provided comprising the successive steps of: (a) fermenting wort containing fermentable sugars with yeast to produce beer containing 1-10 vol. % ethanol and flavour substances diacetyl; acetaldehyde; dimethyl sulfide; ethyl acetate; isoamyl acetate; ethyl valerate; ethyl hexanoate; iso-amyl alcohol and 2-methylbutan-1-ol; (b) contacting the fermenting wort or beer with porous adsorbent particles, selectively adsorbing the beer flavour esters ethyl acetate, ethyl hexanoate, ethyl valerate and isoamyl acetate; (c) separating the adsorbent particles; (d) desorbing a portion of the beer flavour esters from the adsorbent particles; and (e) adding a fraction of the desorbed beer flavour esters to the flavour adjusted beer or to another beer, wherein the amount of beer flavour esters added is 5-95 wt. % of the amount of beer flavour esters removed by the adsorbent particles.

Abstract: The invention relates to a method of preparing a protein aggregate, wherein an aqueous protein solution is acidified with a pH that lies above the isoelectric point of the protein. In accordance with the invention, a first protein, which through acidification is able to form a protein aggregate, is acidified in the presence of a second protein in the aqueous solution in order to form a coaggregate comprising the first and second protein, wherein the second protein under identical temperature conditions and pH does not form a protein aggregate in the absence of the first protein. Acidification preferably occurs with the aid of CO2.
