Embodiment 1

[0018] Embodiment 1: (sterilization of Pu'er tea raw material sun-dried green hair tea)

[0019] Directly irradiate with a suspended ultraviolet lamp, choose a lamp with a power of 30w, control the power of not less than 1.5w per cubic meter, and the intensity at 1m> 70μW·cm -2 . Tea disinfection was irradiated at distances of 25cm, 45cm, and 60cm, and the irradiation time was 30min, 60min, and 120min, respectively. After being sterilized by ultraviolet light, it can kill harmful microorganisms and miscellaneous bacteria in the tea, laying a good foundation for the next step of processing.

[0020] Pu-erh tea raw materials sterilized by ultraviolet lamps are used in the processing of Pu-erh tea. Since there is no interference from bacteria, the quality of Pu-erh tea has been significantly improved.

Embodiment 2

[0021] Embodiment 2: (sterilization of production workshop)

[0022] Basically the same as Example 1, the difference is: the irradiation distance is 2m, and the irradiation time is 100min.

Abstract

The invention relates to the application of ultraviolet light sterilization technology in processing Pu'er tea, wherein the ultra-violet light sterilization technique is employed into the production process of Pu'er tea, more specifically, into the sterilization of Pu'er tea raw material and workshops. The production process also comprises the conventional heating, sterilizing with alcohol, hydrogen peroxide and ozone. The quality and stability of the Pu'er tea can be improved.

Description

Technical field: [0001] The invention relates to an ultraviolet light sterilization method in Pu'er tea processing, belonging to the technical field of optical applications. Background technique: [0002] As we all know, microorganisms are an important part of the biological world and are invisible to the naked eye. However, microorganisms play an important and irreplaceable role in the ecological environment and the relationship with human beings, and are closely related to human production and life. Microorganisms exist widely in nature and there are many kinds. As long as the conditions are suitable, they can grow and reproduce on various media, causing product quality changes, performance degradation, and even devastating damage. Especially in food processing, it has become a key factor in controlling food quality and hygiene safety. Therefore, the technology of controlling microorganisms——sterilization, has become one of the focuses of technical research. [0003] Du...
