The present invention abstract describes the steps of a process for the preparation of green tea and the respective end product, wherein, in the initial step of the proposed process, the young leaves (buds) of yerba mate are subjected to steam at between 90 and 100° for a certain time, the moisture is removed from the steaming step, and, after passing through the steam (steaming step) and twisting, the leaves are cooled (cooling step), rolled (1.sup.st rolling), dried for the first time (1.sup.st drying), rolled for the second time (2.sup.nd rolling), dried for the second time (2.sup.nd drying) and separated (segregation step).

The present invention discloses an apparatus and a method for extracting a component in a solid by using nano-bubbles, the apparatus including a reaction container configured to hold a solid to be extracted, a nano-bubble generating device configured to generate a liquid containing nano-bubbles, and an energy generator, wherein the liquid containing nano-bubbles is used to be mixed with the solid to be extracted, and the energy generator is used to emit energy to the reaction container to burst the nano-bubbles and enhance the extraction effect of the solid in the liquid.

A process for infusing a consumable substance is described. The process includes the steps of placing a desired amount of an infusion material into a chamber at atmospheric pressure, placing a desired amount of consumable substance into said chamber, sealing said chamber from the surrounding atmosphere, and applying at least one reduced pressure cycle within said chamber. Methods for separating the infusion material from the consumable substance after completion of the infusion process are also described. In addition, devices for infusing liquids or consumable substances, and/or brewing beverages are described. The present nvention relates to an apparatus for brewing beverages or infusing a consumable substance comprising a vessel, said vessel comprising a sealable chamber for holding a brewing or infusion material and a liquid or consumable substance, and a filter assembly connected to the sealable chamber; a liquid supply and conduit for introducing at least a portion of said liquid supply into said sealable chamber; and a vacuum source and conduit for reducing pressure in said sealable chamber.

A tea spirit and a method for preparing the same are provided. The method comprises steps crushing tea leaves and soaking the crushed tea leaves in a solvent to obtain a tea suspension; subjecting the tea suspension to distillation under reduced pressure to obtain a tea aroma extract and a remaining tea pulp; filtering the tea pulp to obtain a tea soup, and subjecting the tea soup to concentration under reduced pressure and filtering the tea soup to obtain a filtrate; adsorbing the filtrate with macroporous adsorption resin, then adding food-grade anhydrous alcohol, letting the resultant mixture stand, separating solid from the mixture and drying the solid to obtain a tea theanine extract; and mixing the tea aroma extract and the tea theanine extract with Chinese baijiu to obtain the tea wine. The tea wine as obtained has both tea aroma and wine aroma, and also has an improved intoxication tolerance time.

Provided is a beverage composition, including: non-polymer catechins; and caffeine, the beverage composition satisfying the following requirements (A), (B), and (C): (A) a mass ratio of caffeine/non-polymer catechins is 0.180 or less; (B) particles contained in the beverage composition have an average particle size of 3 μm or less; and (C) a turbidity is 30 NTU or more.

An aromatizing material is disclosed that has green layer aroma and makes one feel its aroma in a sustained way. The tea aromatizing liquid composition comprises dimethyl sulfide and β-ionone, and has a weight ratio of β-ionone content to dimethyl sulfide content which is adjusted to be in the range of from 0.01 to 3.5.

Disclosed is the use of compounds according to Formula (I) and/or Formula (II)
