Abstract—In this study, 2D-COS (two-dimensional correlation spectroscopy) combined with ATR-MIR (attenuated total reflection mid-infrared) spectroscopy was used to quantitatively classify sliver carp surimi adulterated with different levels of hairtail surimi. ED (Euclidian distance) and CC (correlation coefficient) between 2D correlation spectrums of different surimi samples were used for this purpose. Results showed that the sliver carp surimi adulterated with different levels of hairtail surimi samples (5%, 10%, 20%, 40%, 60%, 80%) all could be classified correctly. From above we could conclude that the 2D-COS combined with ATR-MIR spectroscopy had the potential in classifying adulterated surimi samples.
