After review by the State Intellectual Property Office of the People’s Republic of China, Beijing Zhifengtang Propolis’ extraction, purification methods and special equipment have simultaneously obtained national patents and are protected by law. This patent not only retains more than 300 active ingredients in propolis from being destroyed, but also has heavy metal residues of only 0.01ppm, which is less than 20 times lower than the national standard, so that the produced propolis can exert its maximum effect.
Breaking through Eleven Years of Scientific and Technological Problems
In 1999, Beijing Zhifengtang cooperated with the national “Ninth Five-Year Plan” key scientific and technological research project group, the Propolis Research Group, and had the expertise of the research team. Advanced technology.
In 2006, Beijing Zhifengtang exclusively used ultrasonic technology to extract propolis and successfully experimented. This technology makes the molecules of propolis smaller and easier for the human body to absorb.
At the end of 2009, the extraction and purification of Beijing Zhifengtang propolis obtained a national patent. This technology is exclusively owned and protected by the laws of the People's Republic of China and the State Intellectual Property Office.
Innovation of Production Equipment in Eleven Years
Beijing Zhifengtang has exclusively owned the world’s first-class propolis research team in the early stages of cooperation with the national “Ninth Five-Year Plan” key scientific and technological research project team. Advanced cold countercurrent propolis extraction equipment.
In the middle of the company's development, Beijing Zhifengtang independently developed ultrasonic propolis extraction equipment.
In 2009, Beijing Zhifengtang once again had special equipment for propolis production, and this equipment obtained a national patent.
