Abstract: 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.

Abstract: A transport container especially suitable to be supported on a cart or trolley, and also suitable for use in an aircraft, if desired, is constructed as a parallelepiped. Two oppositely located doors are connected by hinges to a frame structure. The hinges form part of the frame structure and allow the doors to open through an angle of 270.degree.. Corner braces having mutually perpendicular tenons mate with tubular metal stock such as sectional rods to form the frame of the container. The metal rods have U-rails for the mounting of wall, floor, door, and cover plates. A door locking mechanism is located in a hollow chamber of a door member or stile. The locking mechanism includes an interconnection of a sliding bar and two lock bolts. The rotation of a door handle actuates the lock bolts which retract into the stile for opening the door.
