##STR00001## wherein R1=H or OH R2=H or Apiose R3=H or Rhamnose as sweetener and/or sweetness enhancer and/or masking agent for the unpleasant taste of another sweetener.

A kombucha brewing device includes two brewing chambers; a first stage (F1) fermentation chamber, and second stage (F2) fermentation chamber. A lid covers both chambers, and may include a first portion for the F1 chamber and a second portion for the F2 portion. The F1 portion of the lid may include a gasket and removable fabric cover insert. A base containing both chambers may include separate or segmented heating elements and temperature sensors associated with each chamber. A temperature controller may maintain the first chamber within a first temperature range and maintain the second chamber within a second temperature range by monitoring information from the temperature sensors and activating and de-activating the heating elements as appropriate.

The present invention relates to a black tea product comprising a preservative composition, wherein the black tea product is a ready-to-drink beverage or a beverage concentrate, wherein the preservative composition comprises at least 3 compounds selected from: hexanal, E-2-hexenal, E-2-hexenol, E-linalool oxide, methanol and methyl salicylate.

The present invention relates to a preservative composition consisting of at least 3 compounds selected from: hexanal, E-2-hexenal, E-2-hexenol, E-linalool oxide, methanol and methyl salicylate, and also to a preserved foodstuff comprising such a preservative composition.

An extract liquid production method, comprising: using deionized water to extracting a material to be extracted with deionized water, and discharging an extract solution after extraction is completed to obtain extract residues; adding deionized water to the extract residues to perform extraction, and discharging the extract solution after extraction is completed; optionally, repeating step two; and mixing the extract solutions obtained in the previous steps together to obtain an extract liquid. The present application also relates to an extract liquid obtained by the method, and a container-packed beverage obtained directly from or by diluting the extract liquid. In the present method, multiple extractions are carried out, thereby effectively increasing the extraction yield, reducing product cost, shortening the extraction time, and improving production efficiency, and also effectively inhibiting the dissolution of bitter substances, thus improving the flavor of the beverage.

A brewing guide device is provided. The brewing guide device includes a communication device, a processing device, and a display device. The communication device obtains real-time weight information and real-time time information from an electronic scale. In a first brewing stage, the processing device determines whether the flow rate is higher than, equal to or lower than a first threshold according to the real-time weight information and the real-time time information to generate a first display instruction. According to the first instruction, the display device displays a first water line corresponding to the real-time weight information, a first target line corresponding to the first brewing stage, and a first display pattern corresponding to a first display block below the first target line on a display interface, wherein the level of the first water line is lower than or equal to the first target line.

A beverage extraction device includes a mesh member, a cover member that is movable between a first position and a second position; a scraper portion, an upper end portion of which is pivotally supported by the cover member with a lower end portion of the scraper portion being swingable along a vertical direction, that takes a basic attitude in which the lower end portion is positioned lower than the upper end portion under a normal condition, the lower end portion being configured to slide on the mesh member when the cover member is moved from the first position toward the second position; and a contact member configured to come into contact with the scraper portion sliding on the mesh member to cause the scraper portion to take an attitude in which the lower end portion swings upward when the cover member approaches the second position.

A semi-solid composition comprising a gelling component in a sufficient amount to provide a cohesive gelled product, a caffeinated component comprising caffeine, wherein the caffeinated component is bitter, and a complexing component, wherein the complexing component is configured to reduce the bitterness of the caffeinated component by complexing with the caffeinated component.
