The compositions reduce oxalate levels in dietary sources of oxalate and are useful in reducing oxalate levels and reducing stone disease in patients. The invention provides methods of extracting and purifying oxalate oxidase from American chestnut leaf. The invention provides methods of extracting oxalate from biological samples.

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.

A diketopiperazine mixture suitable for mixing with a food or drink and a method for producing the mixture. High-temperature and high-pressure treatment of plant peptides in a liquid allows production of a plant extract containing a high concentration of diketopiperazines including cyclo-leucyl-leucine and cyclo-leucyl-phenylalanine. Diketopiperazines having excellent flavor derived from a plant natural product and can produce a food or drink provided with the functions of the diketopiperazines by directly mixing the diketopiperazines with the food or drink.

The present invention abstract describes the steps of a process for the preparation of black tea and the respective end product, wherein, in the initial step of the proposed process for producing black tea, the young yerba mate leaves (buds) are subjected to withering for a certain time. Next, the already withered leaves are rolled; next, the fermentation is carried out, and after such fermentation, drying and segregation are performed.

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.

A gluten-free fermented beverage for human consumption includes a mixture including tea and alcohol. The alcohol is formed by a single culture yeast and fermentable sugar not derived from grain. A method for making the beverage includes steeping a form of tea leaves in water to form a tea, adding a form of yeast nutrient to the tea, adding a fermentable sugar not derived from grain to the tea, adding a single culture yeast to the tea, fermenting the tea mixture, adding citric acid before and/or after the step of fermenting, filtering the fermented tea, and carbonating the fermented tea.

At least one isolated lactic acid bacteria strains selected from the following: TSP05 (Lactobacillus plantarum), TSF331 (Lactobacillus fermentum) and TSR332 (Lactobacillus reuteri) is provided. The above-mentioned active or inactive lactic acid bacteria strains have a function of hepatoprotection and is used in a form of a food composition or a pharmaceutical composition.

The present invention provides a lactobacillus strain-containing pharmaceutical composition and food composition for improving of kidney disease and inhibiting inflammation, which comprises an isolated lactic acid bacteria strain. The isolated lactic acid bacteria strain is at least one selected from a group including BLI-02 strain, CGMCC No. 15212, Bifidobacterium longum subsp. infantis, TYCA06 strain, CGMCC No. 15210, Lactobacillus acidophilus, VDD088 strain, CGMCC No. 15211, Bifidobacterium bifidum, and combinations thereof.

An apparatus used to ferment a liquid during kombucha manufacture includes a bonnet. The bonnet is configured to cover an opening of a container. The container defines a volume to hold the liquid. The container has a lip that defines the opening. The bonnet further includes a filter. The filter is permeable to a gas and has a pore size. The bonnet includes an elastic member. The elastic member is coupled to the filter. The elastic member is elastically engageable with the lip such that when the bonnet is attached to the container the bonnet covers the opening and the elastic member is removably sealable to the lip. When the bonnet is engaged with the lip, a gas can pass through the filter and particles larger than the pore size are kept out of the liquid by the filter during fermentation of the liquid, thereby preventing contamination of the liquid.

The present invention discloses a method for the production of a room-temperature acidic beverage containing sporic Bacillus coagulans, which comprises the following steps: an acidic beverage is prepared and sterilized under sterilization conditions corresponding to 750 C to 110 C. for 23 to 33 s; sporic Bacillus coagulans is then dispersed into sterile water, and the Bacillus coagulans solution thus obtained is pasteurized under pasteurization conditions corresponding to 70 to 90 C. for 23 to 33 s; the acidic beverage obtained following sterilization and the sporic Bacillus coagulans solution obtained following pasteurization are placed in canned packaging to obtain a room-temperature acidic beverage containing sporic Bacillus coagulans. By employing a two-step sterilization process, said method ensures that the concentration of active sporic Bacillus coagulans conforms to relevant standards while maintaining the stability of the acidic beverage, and significantly extends the shelf-life of the acidic beverage.
