Abstract

Decolorization and deprotein of inulin crude extract was studied by the method of resin. The results showed two kinds of ion exchange resin( D280 and D151) constituting series resin for crude extract inulin decolorizating were the best through static and dynamic screening test. The best decoloration and deprotein condition were the two resins m( D280) ∶ m( D151) = 2 ∶1,p H6.5,the flow rate 3.19 m L / min. Under these conditions,purification inulin crude extract maximum volume of 28.3m L /( g resin),crude extract of the decolorization rate,the rate of removal of protein,inulin retention rate were 90.1%,88.9% and 96.8%.
