水洗羽绒羽毛中残脂率测定方法比较

Comparison of measurement results of residual fat content in washed down and feather

采用国标索氏抽提法和加速溶剂萃取(ASE)法对水洗羽绒羽毛中的残脂率进行测定。结果显示,两种方法精密度、准确度一致;加速溶剂萃取(ASE)法具有前处理简单,有机溶剂用量少、快速,对实验室污染少等特点,是值得推广应用的水洗羽绒(羽毛)残脂率快速检测方法。

National standard Soxhlet extraction and ASE were applied respectively for measuring the residual fat content in washed down and feather. According to the results,the two methods were consistent in precision and accuracy. ASE was characterized by simple pre-processing,small amount of organic solvent,rapidness,and little pollution to the laboratory,etc. It is an approach worth promoting for the rapid residual fat content detection in washed down and feather.
