Problems solved by technology

[0003] However, in the current production of tea paste, there is still a shortage of simplification of the extraction process. In order to increase the extraction rate, a higher extraction temperature is used, which will easily inactivate the enzymes in the tea leaves in a large range, and lose the nutrients and nutrients in the tea paste. The "kinetic energy" of the further transformation of the aroma components will cause the quality of the tea paste to decline. I

[0040] Preparation of tea paste:

[0041] Firstly, clean the cooked tea of ​​grade 1~3 that has been stored for 3 years, remove impurities, and crush it to a size of 60 mesh for later use. Then, put the pulverized tea powder raw material in an extraction tank with an ultrasonic device, add deionized water at 60°C according to the material-to-liquid ratio of 1:10, and extract once at a power of 240W for 20 minutes each time , to collect the low-temperature extract. According to the material-to-liquid ratio of 1:5, add deionized water at 80°C, extract once, and extract for 20 minutes each time, collect the high-temperature extract, and mix the second extract at a ratio of 4:1 to obtain the total extract. Extraction. After the total extract is naturally cooled to room temperature, the tea dregs are removed through a filter membrane with a pore size of 1 μm, and then the clarified extract is passed through a filter membrane with a pore size of 0.001 μm and concentrated into a th...

[0045] Preparation of tea paste:

[0046] Firstly, clean the cooked tea of ​​grade 1~3 that has been stored for 3 years, remove impurities, and crush it to a size of 80 mesh for later use. Then, put the pulverized tea powder raw material in an extraction tank with an ultrasonic device, add distilled water at 40°C according to the ratio of material to liquid 1:15, and extract twice at a power of 360W, each time for 10 minutes, and collect Low temperature extract. Then according to the ratio of material to liquid 1:10, add distilled water at 60°C, extract twice, each time for 10 minutes, collect the high-temperature extract, and mix the second extract at a ratio of 3:1 to obtain the total extract . After the total extract is naturally cooled to room temperature, the tea dregs are removed through a filter membrane with a pore size of 0.5 μm, and then the clarified extract is passed through a filter membrane with a pore size of 0.001 μm and concentrated into a thick paste with a...

Abstract

The invention discloses active tea cream high in extraction rate and complete in beneficial component preservation and a preparation method thereof, and belongs to the technical field of tea leaf deep processing. The active tea cream comprises the following components by weight: 30 to 50 % of tea polyphenol, 20 to 30 % of tea polysaccharide, 6 to 10 % of free amino acid and 3 to 4 % of caffeine, and the sum of the weight percentage of the components is not larger than 100 %. The preparation method comprises processes of stocking, extracting, dirt-removing, condensing and forming: placing pulverized tea leaves in an extracting jar, adding an extractive at the temperature of 40 to 60 DEG C according to the feed-liquid ratio of 1: (10 to 15), extracting once or twice, extracting for 10 to 20 min every time, and collecting low temperature extract liquid; adding an extractive at the temperature of 60 to 80 DEG C according to the feed-liquid ratio of 1: (5 to 10), extracting once or twice, extracting for 10 to 20 min every time, and collecting high temperature extract liquid, mixing the extract liquid gained after double extraction according to certain proportion to gain total extract liquid, and gaining the active tea cream after dirt-removing, condensing and drying. The preparation method is high in extraction rate, complete in beneficial component preservation and simple in manufacturing technology; the prepared active tea cream is rich in nutrition, strong in fragrance and mellow in taste, and has a good market popularizing value.

Description

technical field [0001] The invention belongs to the technical field of tea deep processing, and in particular relates to an active tea paste with high extraction rate, complete retention of beneficial ingredients, rich aroma and mellow taste and a preparation method thereof. Background technique [0002] Tea paste is the essence of tea, which has high drinking value and health value, and has been used as a tribute since ancient times. Modern tea paste processing technology improves the production process, and refines the tea raw materials through a series of processes such as extraction, purification, concentration, and drying into small, light, and portable small pieces, and has the effect of lowering blood fat, blood pressure, and blood sugar. , anti-fatigue, anti-aging, improving microcirculation and preventing atherosclerosis and cardiovascular and cerebrovascular diseases, are loved by more and more consumers. [0003] However, in the current production of tea paste, t...
