Problems solved by technology

As ZL03117108.7 in the Chinese patent literature discloses a kind of Pu'er tea beverage, its technical scheme has the following problems in industrialized production: the tea leaves are pulverized into tea powder and then the beverage is made, which will cause the loss of aroma components and make the beverage Precipitation is easy to occur in the medium; its spraying, wet stewing, and low-temperature standing precipitation processes increase the processing time (30 hours to 73 hours), which also increases the chance of microbial contamination and increases production costs; its low-temperature standing The process temperature is low and requires more energy; because the tea liquid is rich in amino acids, it is easy to deteriorate, the processing time is long and there is no effective sterilization method, making it unsuitable for large-scale industrial production; after the tea is crushed, caffeine is more likely to be extracted After that, the bitterness and astringency of Pu’er tea beverages will further increase, making some people unable to adapt, so they can only improve the taste by adding additives, which affects the unique fragrance of Pu’er tea. Improve the appearance quality of the finished product

Abstract

The invention provides a process for producing Pu'er tea beverage which comprises, removing part of the caffeine in the Pu'er tea before extraction, carrying out hot water circulation extraction at 75-95 deg C, cooling the extraction tea juice to 10-15 deg C within 2 minutes, removing tea milk cheese through filtration by centrifugal machine, adjusting the pH of the tea liquid to 5.8-6.5, carrying out instantaneous sterilization at super high temperature, cooling down to 75-85 deg C, finally loading into bottles.

Description

technical field [0001] The invention belongs to the technical field of food, and in particular relates to a production method of a thirst-quenching and nutritious beverage——Pu'er tea beverage. technical background [0002] Pu-erh tea is a traditional famous tea with special characteristics in Yunnan. Its production process and product features are unique. It uses large-leaf sun-dried green tea from Yunnan big-leaf species in a certain area of ​​Yunnan Province as raw material, and is processed into loose tea and pressed tea after post-fermentation. . The appearance of the tea is brownish red, the inner quality of the soup is thick and bright, the aroma is unique and fragrant, the taste is mellow and sweet, and the bottom of the leaves is brownish red. In recent years, studies have shown that Pu'er tea has the effects of warming the stomach, losing weight, lowering fat, preventing arteriosclerosis, preventing coronary heart disease, lowering blood pressure, anti-aging, anti-...
