Provided is a method for producing, from a tea material, a tea extract, which has a refreshing flavor, i.e., showing a natural, fresh and rich aroma, a clean sweetness and a clean deliciousness with little miscellaneous taste and no undesirable taste, comprising: (i) collecting aroma components from the tea material by steam distillation; (ii) enzymatically treating the distillation residue to give an enzymatically treated extract; and (iii) mixing the enzymatically treated extract obtained in (ii) with the aroma components collected in (i).

Method for producing tea extract

PROBLEM TO BE SOLVED: To provide an excellent method for manufacturing an aroma concentrate with little reduction in aroma and a good aroma balance. SOLUTION: The method for manufacturing the aroma concentrate comprises a step of producing a distillate containing the aroma by steam distillation of a natural raw material, a step of producing extract by adding water to a steam distillation residue, a step of mixing a part or the total of the resultant extract with the distillate containing the aroma, and a step of concentrating the mixture using a reverse osmosis membrane.

Method for concentrating aroma using reverse osmosis membrane

PROBLEM TO BE SOLVED: To provide a method for producing tea extract having excellent aroma and flavor and also excellent in taste even after a sterilization process. SOLUTION: The method for producing the tea extract comprises the following (1)-(4) steps: (1) a step of soaking or moisturizing tea leaves into or with warm water; (2) a step of extracting the tea leaves obtained in the step (1) with steam and collecting distilled liquid; (3) a step of extracting residue after distillation with water and collecting extract liquid; and (4) a step of mixing the distilled liquid obtained in the process (2) and the extract liquid obtained in the process (3).

PROBLEM TO BE SOLVED: To provide a method for producing a natural flavor with improved shelf stability, which is produced by a steam distillation method.SOLUTION: A method for producing a natural flavor excellent in shelf stability comprises: passing a condensate, which is obtained by performing steam distillation of a plant raw material containing an aroma component, through a synthetic adsorbent; and eluting a component adsorbed by the synthetic adsorbent with a ≥90% aqueous alcohol solution, thereby recovering the aroma component.

Method for producing natural flavor excellent in preservability

The invention discloses a preparation method for a green tea type extract. The preparation method comprises the following steps of 1, crushing tea leaves through a crushing machine, and mixing the tea leaves with deionized water containing ascorbic acid, so as to obtain tea leaf fragrance recycling liquid, raw tea water and tea extracting solution residues by adopting a gas-liquid backflow contact extraction method; 2, cooling the tea extracting solution residues to be lower than 60 DEG C, mixing the tea extracting solution residues with the raw tea water, performing primary extraction, then cooling the rest of the tea extracting solution residues to be lower than 60 DEG C, adding the raw crushed tea leaves, uniformly mixing the tea extracting solution residues and the raw crushed tea leaves, and performing secondary extraction; 3, performing centrifugation and filtration on all the extracting solution obtained in the second step, concentrating the extracting solution to prepare concentrated tea liquid with the high concentration; 4, mixing the concentrated tea liquid obtained in the third step with the tea leaf fragrance recycling liquid obtained in the first step to obtain the green tea type extract. The green tea type extract prepared by adopting the preparation method smells good and tastes delicious; furthermore, a preparation technology is simplified, and the extraction efficiency is high.

Preparation method for green tea type extract

PROBLEM TO BE SOLVED: To provide a method of producing tea extract which has a subtle top feeling, and an excellent aroma or taste even after manufactured as a tea drink, has high strength, and is excellent in a flavorSOLUTION: A recovered solution 10 is obtained by significantly collecting an aroma gas component with the subtle top, which has not been able to be collected in a conventional collection method, by causing the aroma gas emitted by steam distillation to contact water drops The tea extract can be obtained by adding the recovered solution to an extracted solution 13 of distillate residues on which the steam distillation is performed

PROBLEM TO BE SOLVED: To provide a method for easily extracting tea extract suppressed in astringent taste particular to green tea while imparting delicious taste inherent in the tea leaves to a green tea beverage. SOLUTION: The method for extracting tea extract comprises extracting green tea leaves in the presence of protease, and further making the protease act on the obtained extract liquid.
