Application of Foam Separation Technology to Tea Saponin Extraction

Abstract:

In this paper, a purity of 52.58% crude tea saponin as the research object, through the foam separation technology, tea saponin extraction process was researched. The feed concentration, gas flow rate, liquid volume and pH value were studied through single factor experiment, the rate of recovery and enrichment ratio as evaluation indexes, the single factor experiment results are analyzed, The design of L₉ (3⁴) orthogonal test was applied to confirm the optimum condition: the initial feed solution concentration 0.3mg/ml, air velocity 100ml/min, pH value of 6.5, liquid volume 35ml, enrichment ratio of 3.7896, the recovery rate 82.06%. The purity of the product reached 89.48% under the optimal operation conditions. The results showed that the foam separation techniques is applicable to tea saponin extraction.
