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.

An inventive method and a device for the biotechnological reduction of sugar substances in fruit educts for the purpose of obtaining low-sugar fruit products characterized by enzymatic and/or fermentative reaction processes. Said method is characterized by a closed-loop control process, by means of which the pH value in the low-sugar fruit product is adjusted to a predetermined higher value, as compared to the pH value in the fruit educt, in such a way that during the reduction of the sugar substances by at least 30% by weight to less than 40% by weight, the pH value is increased between 0.6 and 1.0 pH units; or that during the reduction of the sugar substances by at least 40% by weight to less than 50% by weight, the pH value is increased between 0.7 and 1.1 pH units; or that during the reduction of the sugar substances by at least 50% by weight to less than 65% by weight, the pH value is increased between 0.8 and 1.2 pH units; or that during the reduction of the sugar substances by at least 65% by weight to less than 80% by weight, the pH value is increased between 0.9 and 1.3 pH units; or that during the reduction of the sugar substances by at least 80% by weight, the pH value is increased between 1.0 and 1.4 pH units;
wherein the aforementioned pH values may also turn out to be higher or lower by up to 0.1 or up to 0.2 pH units; and/or
wherein, in the case of fermentatively formed sugar alcohols having a % by weight fraction of up to 3.0% by weight, the increase in the pH value with the simultaneous reduction of the sugar substances may turn out to be less by up to 0.3 pH units, as compared to a purely enzymatic process, wherein preferably both values correlate to each other, in particular, linearly.

The present invention can be used to obtain, in particular, low-sugar fruit products, such as fruit pures or fruit preparations or fruit powder or whole fruit beverages (smoothies) or fruit juices and/or vegetable juices (regardless of whether bottled undiluted as NFC juice or rediluted as fruit juice from fruit juice concentrate) or comparable fruit beverages that can be characterized as alcohol-free.

Methods for making oat compositions, such as oat-based beverages, include the steps of combining an oat flour composition with a base to produce a first aqueous mixture having a pH from 8.5 to 11.5, separating the first aqueous mixture into a solid fraction and a liquid fraction, combining the liquid fraction with an acid to form a second aqueous mixture having a pH from 5 to 9, ultrafiltering the second aqueous mixture to produce a UF permeate fraction and a UF retentate fraction, and combining the UF retentate fraction, one or more ingredients, and optionally water to form the oat composition.
