Abstract

In order to recycle polyphenols from the bleaching resin used during the concentrated apple juice processing,the adsorption and separation ability of LSA-900C juice decolonization resin on apple polyphenol was explored. LX-60 resin was also used in purification tests of polyphenols. The results showed that juice decolonization resin LSA-900C had strong adsorption capacity on apple polyphenols,adsorption capacity of 48. 58mg / g. With 70%ethanol as elution solvent,apple polyphenols can be quickly eluted and separated to 89. 07%. Young apple fruit polyphenols were purified by LX-60 resin,the adsorption capacity of this resin was 62. 18mg /g. Using 60% aqueous methanol as elution solvent,the separating rate was up to 92. 31%. Therefore,the use of specific resin for apple polyphenol adsorption and purification is feasible.
