摘　　要：1,3-二羟基丙酮(1,3-dihydroxyacetone,DHA)是一种天然存在的酮糖。本研究提出了一种大孔树脂串联纯化DHA结晶母液的新工艺。通过静态吸附实验筛选树脂,其中D001树脂与315树脂串联能有效去除DHA结晶母液中的色素和蛋白质。试验结果表明,经串联纯化后,母液中DHA色素去除率达97.49%,蛋白去除率达97.05%,DHA收率达93.66%。与传统工艺相比,新工艺保证了DHA母液回收总收率,为DHA结晶母液大规模提取纯化提供了新思路。1,3-dihydroxyacetone(DHA)is a natural ketose.In this study,a new process of purification of DHA crystalline mother liquor by macroporous resin in series was proposed.The resin was screened by static adsorption experiment,in which D001 resin and 315 resin in tandem could effectively remove the pigment and protein in DHA crystalline mother liquor.The results showed that after purification in series,the removal rate of DHA pigment reached 97.49%,the removal rate of protein reached 97.05%,and the yield of DHA reached 93.66%.Compared with the traditional process,the new process guarantees the total recovery rate of DHA mother liquor and provides a new idea for large-scale extraction and purification of DHA crystalline mother liquor.
