| 中文摘要: |
| 采用AB-8大孔树脂吸附分离橄榄油加工废液中的橄榄多酚。分别考察了静态吸附、静态解吸和动态洗脱工艺条件。结果表明：适宜的静态吸附条件为在30℃下用1.5 g预处理的树脂吸附20 mL橄榄多酚质量浓度为1.52 mg/mL的粗提稀释液，吸附3 h时吸附量可达14.43 mg/g；动态洗脱橄榄多酚的适宜条件为洗脱流速1.0 mL/min，依次用蒸馏水、70%乙醇溶液、90%乙醇溶液进行分段洗脱。在静态吸附和动态分段洗脱的组合条件下，纯化所得橄榄多酚的纯度为56.44%，为粗提稀释液的7.93倍。 |
| 英文摘要: |
| The olive polyphenols (OPP) were separated from olive oil processing effluent using AB-8 macroporous resin. The process conditions of static adsorption, static desorption and dynamic elution were investigated respectively. The results showed that the optimal static adsorption conditions were obtained as follows: dosage of pretreated resin 1.5 g, adsorption time 3 h and adsorption temperature 30℃, under these conditions,the adsorption capacity of 20 mL crude extract diluent (OPP mass concentration 1.52 mg/mL) reached 14.43 mg/g; the optimal dynamic elution conditions were obtained as follows: elution rate 1.0 mL/min, subsection elution with water, 70% and 90% of ethanol solutions. Under the combined condition of static adsorption and dynamic subsection elution, the purity of OPP after purification was 56.44%,which was 7.93 times as high as that of crude extract diluent. |
