Embodiment 1
[0019] The application provides a preparation process for tea beverage, comprising the following steps:
[0020] Step 1. Extraction: put fresh tea leaves and pectinase into deionized water together, extract at 2.1~.2.5MPa, 85°C for 15min, the mass ratio of tea leaves, pectinase and deionized water is 1:0.08 : 9, the pH of deionized water is 6.7~7.2.
[0021] Step 2, coarse filtration: after adjusting the temperature of the extract solution to 80°C, perform coarse filtration to obtain a coarse filtrate.
[0022] Step 3, clarification treatment: add 1 gram of citric acidpowder to every 6 milliliters of crude filtrate, and add them together into a centrifuge at a speed of 700 r / min, centrifuge for 2 minutes, and then let stand for 10 minutes.
[0023] Step 4, blending: blending the taste of the tea beverage to obtain a blended liquid.
[0024] Step 5, fine filtration: After the preparation liquid is naturally cooled and lower than 75°C, fine filtration is performed with a doub...
Embodiment 2
[0028] A traditional tea beverage preparation process is adopted, comprising the following steps;
[0029] Step 1, extraction: mix tea leaves and water at a mass ratio of 1:10, and extract at 85°C for 20 minutes;
[0030] Step 2, coarse filtration: coarsely filter the extract to obtain a coarse filtrate;
[0031] Step 3, cooling: cooling the crude filtrate to 5°C;
[0032] Step 4, fine filtration: perform fine filtration on the cooled coarse filtrate;
[0033] Step 5, blending: blending the taste of the tea beverage according to the preset ratio to obtain the blended liquid;
[0034] Step 6. Sterilization: Sterilize at 100°C for 2 minutes;
[0035] Step 7. Filling and capping: Fill and cap with a 500ml plastic bottle before selling.

Abstract
The invention discloses a preparation process of a tea beverage. The preparation process comprises the following steps: step 1, extracting: putting fresh tea leaves and pectinase into de-ionized water; extracting for 15min under conditions that the pressure is 2.1MPa to 2.5MPa and the temperature is 85 DEG C; step 2, roughly filtering; step 3, carrying out clarification treatment: adding citric acid into rough filtrate; after uniformly stirring, standing for 10min; step 4, blending; step 5, finely filtering: after naturally cooling a blended solution to 75 DEG C, carrying out fine filtering treatment; step 6, sterilizing: raising the temperature of fine filtrate to 90 DEG C and carrying out sterilization treatment to obtain a tea beverage finished product; step 7: filling and covering. According to the preparation process of the tea beverage, in a fine filtering process, the fine filtering can be carried out by natural cooling, and additional rapid cooling is not needed, so that the energy consumption in production can be remarkably reduced and the production cost of enterprises is reduced.
Description
technical field [0001] The invention belongs to the field of food processing, and in particular relates to a preparation process of tea beverage. Background technique [0002] Tea is a traditional drink in China with profound cultural heritage and multiple health functions. my country's tea beverages started in the 1990s and are currently in a stage of rapid development. In 2007, the production and sales of tea beverages exceeded 5 million tons, and by 2009 they had exceeded 8 million tons. With the improvement of people's living standards, consumers will have higher and higher requirements on the taste, quality, safety and health care of tea beverages. Diversification, specialization and functionalization will be the main direction of the future development of tea beverages in my country. [0003] The preparation process of traditional tea beverages is: tea leaves—extraction—coarse filtration—cooling—fine filtration—deployment—high temperature sterilization—filling and cap...
