The invention relates to a tea-based beverage comprising probiotics, wherein the probiotics has a live probiotic cell count of ≥6.0 log CFU/ml. The invention further relates to a method of preparing the tea-based beverage having a live probiotic cell count of ≥6.0 log CFU/ml comprising the steps of: mixing tea infusion with sugar to form a mixture, inoculating probiotics to the mixture to form an inoculated mixture, fermenting the inoculated mixture for a pre-determined period of time to form the beverage. In one embodiment, the probiotics comprises Lactobacillus plantarum, Lactobacillus acidophilus, Lactobacillus gasseri, Lactobacillus ermentum, Lactobacillus rhamnosus, Lactobacillus paracasei, Saccharomyces boulardii, Saccharomyces cerevisiae, or a combination thereof.

The present disclosure discloses a method for liquid fermentation of black tea juice by using aged green tea and belongs to the technical field of tea leaf processing. The method comprises the following process steps: mixing aged green tea with hot water for a water bath-assisted extraction; adding a tannase into a crude catechin extract for a water bath-assisted enzymolysis; freeze-withering fresh tea leaves; homogenizing the freeze-withered leaves; pouring a homogenate into a primarily enzymolyzed crude catechin extract, adding a β-glucosidase for secondary enzymolysis and performing fermentation; and treating a fermentation broth by microwave, and performing filtration and cooling to a room temperature.

The present invention relates to a method for preparing a comestible product, in particular a fermented beverage containing stevia extract. A further aspect of the invention is a comestible product obtainable by the method of the invention.

This application provides a temperature control apparatus and a fermented tea manufacturing method. The temperature control apparatus includes: a base housing, a controller, a heating component, an air supply component, and a temperature sensing component, where the controller, the heating component, and the air supply component are disposed in an inner cavity of the base housing; the controller is electrically connected to the heating component; the controller is electrically connected to the air supply component; and the controller is electrically connected to the temperature sensing component; and the controller is configured to perform temperature control, and is specifically configured to: control, based on a temperature detected by the temperature sensing component, the heating component to start or stop working, so that a controlled temperature detected by the temperature sensing component is maintained in a first temperature interval; and control, based on a temperature detected by the temperature sensing component, the air supply component to start or stop working, so that a controlled temperature detected by the temperature sensing component is maintained in a second temperature interval. The temperature control apparatus in this application features a small volume, applicability to household purposes, easy operations, and low costs.

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.

An aspect of the present disclosure relates to a composition for improving respiratory health exposed to particulate matter, which contains a green tea extract, a green tea polysaccharide and a green tea flavonol as active ingredients. The composition provided in an aspect of the present disclosure can improve respiratory health damaged by exposure to particulate matter by enhancing the effect of preventing adsorption of particulate matter to bronchial epithelial cells and activating the cilia of bronchial epithelial cells. The composition provided in an aspect of the present disclosure may decrease blood heavy metal level.

The present invention relates to a green coffee-based composition comprising hydrolysed chlorogenic acid for use in the treatment or prevention of a disorder linked to an increase in plasma postprandial insulin in a subject. The invention relates also to the non-therapeutic use of a composition comprising an esterase treated decaffeinated green coffee extract with an amount of 40-200 mg administered to a subject per day to decrease plasma postprandial insulin concentration. A further aspect of the invention is a process for forming green coffee based compositions.

A method for producing herbal beverages and beverages from rosebay willowherb which have a high content of biologically active substances, particularly gamma-aminobutyric acid (GABA), is disclosed. The method consists in freezing a raw material consisting of rosebay willowherb leaves at a temperature of from −45° C. to 0° C. or cooling the same to a temperature below dewpoint, then heating the raw material to a temperature of 15-25° C. and subsequently grinding it to produce a homogeneous plant mass, treating the resulting plant mass with an aqueous solution of vitamin B6 and with an aqueous suspension of glutamic acid and subsequently fermenting the mass at 22-40° C. for 2-10 hours, then carrying out drying to produce a finished product.
