Application of ultraviolet light sterilization technology in processing Pu'er tea

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 the application of ultraviolet light sterilization technology in Pu'er tea processing, which belongs to the field of optical application technology. 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 technica...
