Nonlinear chemical fingerprint based on chemical oscillatory reaction was a novel technology to analysis sample from nonlinear chemical reaction viewpoint. Milk and its products, as a kind of ideal comprehensive nutritional food, became an indispensable parts of people＇ s daily life. The method of nonlinear chemical fingerprint used to examine the fifteen different kinds of milk and its products for fast and accurate identification and distinction was feasible. The re- sult of examination showed that the nonlinear chemical fingerprint of milk and its products concentrated visual characteris- tic and could be well identified and distinguished. With cluster analysis （CA） and principle component analysis （PCA）, the 15 characteristic date of nonlinear chemical fingerprint could well embody the characteristic of nonlinear chemical fin- gerprint.
