Our first stop was in the Changping area of Beijing, where BGG's production and lab facilities reside. We spent a couple of days touring the buildings, learning about equipment, processes, technologies, research, testing, quality control, product development and overall expertise. During our tour of the extract production facility, we saw how BGG goes from raw material to finished extract.
The point of extensive manufacturing of raw botanical materials is to end up with an ingredient of concentrated actives and related compounds. This makes the extraction process a critical step in production. During our tour we saw the gigantic room housing huge extraction tanks. As explained to us, there were two different types of tanks present, stainless steel- and glass-lined. Which tank type is used depends on factors such as the corrosiveness of the material undergoing extraction. Exemplifying the quality control buyers should want to see in a supplier, each batch being processed in these extraction tanks is monitored for temperature, time, solvent levels and other vital parameters.
