Technology Introduction

For complex natural product extracts, while removing impurity components such as colloidal tannin, white, starch, etc., small molecular target products can pass through the ceramic membrane. The flux is higher than that of traditional ceramics. At present, the developed ceramic membranes have been applied to the high fraction and purification of natural products such as Yingo, pomelo fruit, Tianma, blueberry, blueberry, ginseng, mushroom, stevia bran, and Gankang.
