Licorice Extract (information):
Licorice extract is a medicinal ingredient extracted from licorice. Licorice extract generally contains glycyrrhizin, glycyrrhizic acid, glycyrrhizin, licorice flavonoids, hyoscyamine, formononetin, pelargonine and other ingredients. It has the effects of tonifying the spleen and replenishing qi, clearing away heat and detoxifying, removing phlegm and relieving cough, relieving pain and harmonizing various medicines.
Traditional methods for refining licorice extracts mostly use alcohol precipitation, adding appropriate ethanol to the licorice water extract to precipitate and remove impurities such as mucus, gelatinized starch, pectin, and protein.
However, the process is complicated, the solvent consumption is large, the effective ingredients are easily lost, and the separation efficiency is low.

Membrane filtration technology applied to licorice extract:
Bonatech uses an integrated membrane separation process that combines ceramic membrane separation technology with organic membrane ultrafiltration and nanofiltration separation technology to form a step-by-step filtration separation. The ultrafiltration membrane system is used for clarification and impurity removal, and the nanofiltration membrane system is used for small molecule impurity removal and concentration, which can achieve efficient purification of licorice extracts, and there is no phase change in the process, low energy consumption and no pollution.
