Manufacturing flow chart of Ginkgo Biloba
Ginkgo Biloba extract is made from the leaves of the Ginkgo tree and is often taken in supplement form. The manufacturing process of Ginkgo Biloba extract involves several steps to ensure purity and potency. First, the raw Ginkgo leaves are washed and then ground into a powder. Next, the powder is extracted using 70% ethanol, and the resulting solution is concentrated using vacuum distillation. The concentrated solution is then passed through a resin column to remove any acidic impurities. Finally, the solution is spray-dried to produce a Ginkgo Biloba extract powder free of harmful bacteria and compounds. This high-quality Ginkgo Biloba powder can be encapsulated according to our client’s requirements.
