摘　　要：采用超临界二氧化碳萃取装置提取青稞中的有效成分。实验结果表明在温度60℃,压力25 MPa,流量30kg/h,萃取5 h,β-葡聚糖的含量约3%。与传统的溶剂萃取法和化学法相比,超临界二氧化碳萃取技术具有工艺简单,萃取剂无毒、无污染、无化学物质残留、易于回收等优点。Supercritical carbon dioxide＇extraction device extracted the effective components in highland barley. The experi- mental results showed that the temperature of 60 ℃, pressure 25 MPa,flow 30 kg/h, extraction of 5h, β- glucan oil yield a- bout 3%. With the traditional solvent extraction method and chemical method, supercritical carbon dioxide extraction tech- nology had the advantages of simple process, the advantages of extracting agent was non-toxic, no pollution, no chemical residues, easy recover.
