Problems solved by technology

[0007] At present, the tea concentrates on the market are mainly green tea concentrates, and there are no related black tea concentrates. The category of tea concentrates is relatively single, and the market share of black tea beverages is huge.
Therefore existing tea concentrate can not satisfy people's demand fully, needs a kind of new tea concentrate badly

Embodiment 1

[0059] A preparation method of black tea concentrate, the steps are as follows:

[0060] (1) Tea extraction: use closed extraction equipment to extract tea leaves in hot water, put in 1000kg of tea leaves, add 10000kg~15000kg of RO water at 70℃~95℃, extract for 0.5 hours to 2.5 hours, and cool to 40℃~50 ℃.

[0061] (2) Enzymolysis reaction: add tannase (for example, Tannase-KT05, Kikkoman) 0.2kg, pectinase (for example, RAPIDASE TF, DSM) 10kg, α-amylase (for example, Mycolase, DSM ) 6kg, glucoamylase (for example, Amylase AG 300L, Novozymes) 3kg, add protease (for example, Protease A2SD, Amano) 25kg, enzymolysis reaction for 4 hours to 8 hours, add exoprotease (for example, Flavourzyme 1000L, Novozymes) 2kg, continue the reaction and enzymolysis for 2 hours to 8 hours, and the enzymolysis temperature during the enzymolysis reaction process is controlled at 40°C to 50°C.

[0062] (3) Separation and filtration: After the enzymolysis reaction is completed, use a filter press to...

Embodiment 2

[0073] A preparation method of black tea concentrate, the steps are as follows:

[0074] (1) Tea extraction: use closed extraction equipment to extract tea leaves in hot water, put in 1000kg of tea leaves, add 10000kg~15000kg of RO water at 70℃~95℃, extract for 0.5 hours to 2.5 hours, and cool to 40℃~50 ℃.

[0075] (2) Enzymolysis reaction: add tannase (for example, Sumizyme TAN, New Japan) 0.2kg, add pectinase, Pectinase PL (Amano) 3kg, RAPIDASE PRESSL (DSM) 1kg, ROHAPECT B1L (Germany AB) 2kg, α-amylase (for example, Mycolase, DSM) 6kg, glucoamylase (for example, Amylase AG 300L, Novozymes) 3kg, add protease, ProteAX (Amano) 10.5kg, COROLASE 7089 (Germany AB) 20kg , after enzymatic hydrolysis reaction for 4 to 6 hours, add 2 kg of exoprotease (for example, Flavourzyme 1000L, Novozymes) and continue the reaction and enzymatic hydrolysis for 2 to 8 hours.

[0076] (3) Separation and filtration: After the enzymolysis reaction, use a horizontal spiral centrifuge to separate the...

Embodiment 3

[0081] A preparation method of black tea concentrate, the steps are as follows:

[0082] Except in embodiment 1 with protease (for example, Protease MSD, Amano) 17.5kg, protease (for example, ProteAX, Amano) 7.5kg replaces protease (for example, Protease A2SD, Amano) 25kg, carry out exactly the same as embodiment 1 Operation, the black tea concentrate of product 3 of the present invention is made.

Abstract

The invention relates to a preparation method of a black tea concentrated solution. The method includes the steps that firstly, tea leaves are extracted, wherein after tea leaf raw materials are thrown in, RO water at the temperature of 70-95 DEG C is added, and the tea leaf raw materials are extracted; secondly, enzymolysis reaction is performed, wherein tannase, lyticase, amylase and protease are sequentially added, enzymatic hydrolysis reaction lasts for 4-8 hours, and then circumscribed protease is added; thirdly, separation and filtration are performed; fourthly, the pH value of a black tea extracting solution is adjusted, NaHCO3 is added in the black tea extracting solution, the pH value is adjusted to be 5.0-6.0, and a black tea solution is obtained; sixthly, the black tea concentrated solution is obtained after concentration. The method takes the black tea leaves as raw materials, water serves as solvents in the whole production process, a unique enzymolysis technology is adopted, enzyme preparations can play the maximum application effect, the yield of the product is increased, taste components become richer, the sweet feeling is improved when the black tea concentrated solution enters the mouth, the sweetness after taste is improved, the characteristic flavor of black tea is reserved, and the black tea concentrated solution has tea feeling, and is natural plant extracts and is a high added-value product.

Description

technical field [0001] The invention belongs to the technical field of food processing, in particular to a method for preparing black tea concentrate. Background technique [0002] Tea beverages are the fourth largest beverages in China's beverage market after carbonated beverages, packaged water, and fruit juices, with a market share of about 15%. With the improvement of people's living standards, the requirements for the flavor of tea beverages are getting higher and higher. The quality of beverages is becoming more and more important. [0003] Tea concentrate is made of tea leaves or fresh tea leaves as the main raw material, extracted with water or squeezed with fresh tea leaves, food additives and food processing aids can be added in the production process, a certain proportion of water is removed by physical methods, and processed It is a liquid product that is used as raw and auxiliary materials such as food and beverages. [0004] The tea concentrate prepared by en...
