The second derivative IR spectra show differences concerned with peak position particularly in the range of 1800–1400 cm−1, and especially the differences on lipids content of three surimi become more apparent. In 1710–1600 cm−1 of amide I absorption band, different peak positions, shapes and intensities indicate that the three have different profiles of proteins (Fig. 4). Compared to the other two surimi, HS has strong absorption peaks at 1679 cm−1, 1656 cm−1 and 1631 cm−1, while the peak at 1682 cm−1 in WCS and RCS is much stronger.
