After technological research and development, the company has carried out intensive processing of Theabrownin, which has increased the added value of the product. Theabrownin is an oxidized polymer extracted from tea leaves using modern high-tech biotechnology purely physical methods, without the addition of any chemical solvents. It is the best product for tea. The main component and the most stable component of pigments. High-tech eliminates harmful residues and uses molecular cutting technology to separate pesticide residues, bacteria, heavy metals and other ingredients that may be harmful to human health that may be present in tea.
After years of hard work, the invention patent certificates from the former Zhejiang Agricultural University, Yunnan Agricultural University, School of Chemical Engineering of Shenzhen University, Tang Ren Biology and other institutions as well as relevant experts and engineering and technical personnel finally found the water-soluble extraction of Theabrownin in the molecular structure of tea. method, the purity can reach more than 95%, and has obtained the national invention patent ZL201310713639. , Wenguanfu tea and tea pigment deep processing technology patents, "71 Tea Art Packaging" appearance patents, and an agricultural drone patent for easy replacement of medicine boxes. Hangzhou Zuocheng Ecological Agriculture Development Co., Ltd. has built a 5,000-acre tea garden in Yunnan Jianshui Yunlongshan Ecological Base, a 20,000-square-meter factory in Yunnan Honghe National Economic and Technological Development Zone, a 26,000-acre vine fruit base, and an 8,000-square-meter production base. , creating employment for 10,000 people, and the group has deployed A. sorbifolia tree planting projects in Shaanxi, Henan, and Gansu. The first A. sorbifolia national reserve forest project was settled in Henan Province. The Group cooperates with the local government to carry out targeted poverty alleviation and help revitalize the rural economy.
