以绵新2号黑花生为材料,采用静态吸附和动态吸附法,筛选出对黑花生衣色素吸附和洗脱性能好的大孔树脂,并探讨了大孔树脂纯化黑花生衣色素的工艺条件.结果表明,非极性和弱极性大孔树脂对黑花生衣色素吸附效果较好,其中,HP20大孔树脂对黑花生衣色素的比上柱量、比吸附量和比洗脱量均明显高于其他几种供试大孔树脂.当上样液的pH值为1,上样液花色苷浓度为10 mg/L,吸附温度为20 ℃时,HP20大孔树脂对黑花生衣色素的吸附率较高.采用80%乙醇作为洗脱剂,用量为14倍柱床体积即达到较好的解吸效果.

Peanut skin of the Arachis hypogaea ‘Mianxin No.2＇ cultivar was used as the raw materials. By static adsorption and dynamatic adsorption method, the suitable macroporous resin type with good adsorption and desorption capacity to black peanut skin pigment （BPSP） was screened, and the purification conditions was studied. The results showed that non-polar and weak polar macroporous resin had higher BPSP adsorption capacity. Among the macroporous resin tested, HP20 resin was significantly better in saturation ratio, adsorption ratio, eluation r...
