为回收浓缩苹果汁加工中果汁脱色树脂所吸附的营养物质多酚,探讨了果汁脱色树脂LSA-900C对苹果多酚的吸附解析能力,并利用LX-60树脂进行了多酚的静态吸附、解析纯化等回收试验。结果表明:果汁脱色树脂LSA-900C对苹果多酚有较强的吸附能力,吸附量为48.58 mg/g,用70%乙醇可快速洗脱,一次洗脱解析率达到89.07%;洗脱的苹果幼果多酚用LX-60树脂纯化,其吸附量为62.18 mg/g,用60%甲醇水溶液洗脱,洗脱速率快,一次洗脱解析率达到92.31%。采用特定树脂进行苹果多酚的吸附分离纯化是可行的。

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.
