Study on Purification of Tea Saponin by Foam Separation Method

摘要

Foam separation method was utilized to purify crude tea saponin. The factors influencing the purification were studied, including the effects of original concentration, airflow rate and loading liquid volume. By systematic experiments, the optimal purification technology was determined. Foam separation method showed great advantages such as: low solvent and energy consumption, convenience, environmental friendliness. This work provides useful information for tea saponin purification development.
