摘要

•The discrimination method for melamine-adulterated milk was proposed based on two-trace two-dimensional auto-correlation spectra.•Melamine-adulterated milk was identified using the two strongest auto-correlation peaks combined with LS-SVM.•The proposed method greatly reduced the number of variables, and could get a very high prediction accuracy.
