METHOD AND DEVICE FOR THE BIOTECHNOLOGICAL REDUCTION OF SUGARS IN FRUIT EDUCTS FOR THE PURPOSE OF OBTAINING REDUCED-SUGAR FRUIT PRODUCTS

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 The present invention can be used to obtain, in particular, low-sugar fruit products, such as fruit purées 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.
