Problems solved by technology

[0004] Because Puer tea paste is rich in nutrition, it has good commercial value. However, most of the extraction processes at the present stage are complicated and time-consuming. During the extraction process, it is easy to cause the loss of nutrients inside Puer tea paste, and the extraction rate is low.

Embodiment Construction

[0010] The present invention selects the material-water ratio and the number of extractions as the influencing factors of the extraction rate of Pu'er tea paste, as shown in Table 1.

[0011] Table 1 The influence of different extraction conditions on the yield of tea extract

[0012]

[0013]

[0014] As can be seen from Table 1, when the ratio of material to water is 1:5, although the concentration time is short, the yield is low, only 11.6%, and the waste of raw materials is large; when the ratio of material to water is 1:10 and 1:15 The yields are both higher, and there is little difference between the two. However, the ratio of material to water increases from 1:10 to 1:15. Although the yield only increases by 0.84%, the concentration time increases by 60 minutes.

[0015] It can be seen from Table 1 that the extraction rate increases when the number of extractions is increased; however, it must be considered that the extraction time, filtration times, and concentra...

Abstract

The invention relates to a Pu'er tea paste extraction technology. The invention provides the Pu'er tea paste extraction technology with the characteristics of simple process, short time consumption and high recovery rate. According to the invention, an extraction method is used for extracting the Pu'er tea paste, and the extraction technology comprises the following steps: adding water in fannings of the Pu'er tea, wherein the ratio of the material to water is 1:5-1:15, then extracting for 1-2 times under the temperature of 90 DEG C, wherein each extraction time is 15-20 minutes; and then purifying, concentrating and drying the extracted crude product to obtain the finished product.

Description

Technical field: [0001] The invention relates to a process for extracting Pu'er tea paste. Background technique: [0002] Pu'er tea is a unique local famous tea in Yunnan formed in history. Pu-erh tea is divided into raw tea and cooked tea. Raw tea is made from the fresh leaves of Yunnan large-leaf tea trees grown under the environmental conditions of the Pu-erh tea production area, and is made by processes such as killing greens, rolling, drying in the sun, and autoclaving. , including loose tea and pressed tea. Its quality characteristics are: dark green appearance, pure and long-lasting aroma, strong and sweet taste, clear green-yellow soup, thick yellow-green leaf bottom; cooked tea is made from Yunnan Puerh tea that meets the environmental conditions of the Pu'er tea production area. The big-leaf sun-dried green tea is used as raw material, and it is formed by post-fermentation (it is considered that adding water to increase temperature can promote cell reproduction, a...
