Exploration of Chemical Analysis of Down Extract Liquid
Gu Lehua
Abstract：The pH value,oxygen consumption,turbidity and other indicators of down were detec-ted by the water extraction method.The residual grease was precipitated by the organic solvent ex-traction method to test the residual grease rate.Through this,the impurity content of down products was clarified,and various hygiene and safety indicators were controlled.It provided a theoretical basis for testers and helped solve commercial disputes and compensation cases.The relevant indicators of down products could be effectively detected,which was of great significance for guaranteeing product quality and resolving related commercial disputes.
