Abstract

The invention relates to a method for processing instant tea extract, which belongs to the technical field of tea processing. The method for processing the instant tea extract comprises the following steps: leaching a finished product tea for 1 to 3 times every 3 to 5 minutes, after the tea is immersed by 2 to 5 times volume of purified water; crushing the leached fresh tea into powder of between60 and 80 meshes; immersing the tea by the purified water or condensed water obtained in a concentration step at a temperature of between room temperature and 80 DEG C for 5 to 15 minutes, with waterdosage of between 10 and 25 times of weight of the tea; roughly filtering tea water immersing the finished product tea by a 60 to 80 mesh sieve, and finely filtering the tea water by a 80 to 120 micron filtration fabric; roughly filtering tea water immersing the fresh tea powder by a 100 to 150 mesh sieve, and finely filtering the tea water; reversely concentrating tea liquor to 15 to 30 percent volume of original tea water; and decompressing, vaporizing and concentrating the tea liquor at low temperature to produce liquid tea extract with water content of between 30 and 60 percent; or directly decompressing, vaporizing and concentrating the tea liquor under pressure of less than or equal to 0.07 pressure atmosphere at a temperature of between room temperature and 50 DEG C to produce the liquid tea extract; and drying the liquid tea extract to obtain solid instant tea extract. The method has the advantages of low production cost and rich tea extract flavor.

Description

Technical field: [0001] The invention relates to a processing method of instant tea paste, which belongs to the technical field of tea processing. Background technique: [0002] There are many kinds of mature solid tea paste production technologies (nearly more than 20 patents have been applied for). Existing solid tea paste production mostly adopts high-temperature soaking, high-temperature concentration; drying process is made, and individual production technology uses freeze-drying technology. Because the production of tea paste has gone through a high-temperature stage, in addition to high production costs, the tea paste also has the problem of weak tea flavor and no tea fragrance. [0003] Through document retrieval technique, do not see the document report identical with the present invention. Invention content: [0004] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a kind of production cost is low, the processin...
