The principle is that the fat in the feather sample is dissolved in organic solvents (such as diethyl ether, diethyl ether, etc.), and the extracted fat is obtained after the solvent is volatilized. After weighing and calculating, the fat content can be obtained, namely the residual fat rate.

If fat and oil content is high, down and feather products will have an unpleasant smell.
