Description

Technical Field

[0001] The invention belongs to the technical field of tea sets, and relates to a device for purifying tea leaves by plasma, in particular to a tea set with a plasma purification function. Background Art

[0002] Mycotoxins are secondary metabolites of various fungi, widely present in various foods, and can cause mild to severe diseases, including skin necrosis, leukopenia, immunodeficiency, and even liver cancer. They seriously threaten human health and safety and have become one of the hot issues in the field of food safety. Common mycotoxins include aflatoxin (AFTs), ochratoxin (OTs), deoxynivalenol (DON), fumonisin (FUMs), zearalenone (ZEN), paramycin (PAT) and citrinins (CITs).

[0003] Pu'er tea is made exclusively from fresh leaves of one bud, two leaves or three leaves of large-leaf tea varieties. The tea leaves are inactivated by enzymes, twisted, dried, rolled, and then steamed, compressed and post-fermented (natural aging or stacking) to set. Under the action of fermented microorganisms and microbial enzymes, the biotransformation of carbohydrates and phenolic compounds in the tea leaves gives Pu'er tea a unique taste and flavor.

[0004] Fermentation and storage are the main ways for Pu'er tea to be infected by harmful fungi. During the fermentation process, high temperature and high humidity conditions are conducive to the growth of microorganisms and the metabolic transformation of tea, but if Pu'er tea is contaminated by harmful fungi during the pile fermentation process, then there is a risk of black tea being contaminated by mycotoxins. Aflatoxin B (AFB) and ochratoxin A (OTA) are considered to be the two most serious mycotoxins that pose the greatest health hazard.

[0005] Plasma, the fourth state of matter, is an ionized gas that contains various reactive charged particles, such as electrons, ions, free radicals, metastable excited states, and vacuum ultraviolet radiation, which have enough energy to initiate chemical reactions. Cold atmospheric plasma (CAP) is produced by injecting electrical energy into one or more working gases (oxygen, helium, argon, or air, etc.) filled between two electrodes at atmospheric pressure and room temperature. During the CAP excitation process, a variety of substances are produced, such as ultraviolet rays, charged particles, reactive oxygen species (ROS), and reactive nitrogen species (RNS). Due to the different discharge methods, common CAP excitation devices mainly include six types: dielectric barrier discharge (DBD), atmospheric-pressure plasma jet (APPJ), and corona discharge. DBD produces CAP between two electrodes separated by an insulating material (such as cerium, quartz, etc.) as a barrier layer.

[0006] CAP has significant disinfection and purification capabilities at room temperature, and is clean and safe, and will not introduce chemical pollution after treatment. Therefore, the application of CAP technology in the field of food purification and preservation has been widely explored. Therefore, how to apply CAP technology to the field of household tea sets without affecting the quality and safety of Pu'er tea has become an urgent problem to be solved. Summary of the invention
