摘　　要：为开发利用羽毛绒蛋白资源,研究了其溶解性能,采用三元溶剂、溴化锂和离子液体([Amim]Cl)3种不同的溶解体系,测试不同溶解工艺参数下羽毛绒的溶解度,并通过纤维图像自动采集和识别系统监控羽毛绒在溶解过程中的形貌变化。结果表明:三元溶剂和溴化锂溶解羽毛绒时溶解度低,而[Amim]Cl能将羽毛绒全部溶解。采用紫外-可见分光光度计和傅里叶红外光谱仪对离子液体溶解体系进行测试,结果表明,羽毛绒溶于离子液体在312 nm处有特征吸收。基于特征吸收建立了羽毛绒蛋白的定量分析曲线,该曲线具有较高的测试精度;[Amim]Cl可打断羽毛绒蛋白二硫键,且不破坏蛋白质构象。In order to develop and utilize feather and down protein resources,the solubility of feather and down was studied firstly in different dissolution systems including ternary solvent,lithium bromide and ionic liquid（[Amim]Cl）,and the solubility under different process parameters was tested,and the morphological changes of feather in the process of dissolution were monitored by automatic image acquisition and recognition system.The results show that feather and down have low solubility while being dissolved with ternary solvents and lithium bromide,but could be dissolved completely in the [Amim]Cl ionic liquid; at the same time,the [Amim]Cl dissolution system of feather and down has been analyzed by UV-Vis and FT-IR.The UV-Vis results show that a characteristic absorption exist at a wavelength of312 nm and the quantitative analysis curve of protein is given; and FT-IR results show that disulfide bond of feather and down protein can be destroyed,without destroying the protein conformation when being dissolved in the ionic liquid of [Amim]Cl.
