Figure 1
FTIR spectra in the mid-infrared region of the studied proteinaceous materials (black line: hide glue, gray line: bone glue, light gray line: casein) using different analysis modes. From top to bottom: total reflection mode before the KKT correction, total reflection mode after the KKT correction, and transflection mode. Spectral regions of (a) 4000-375 cm−1 and (b) CH stretching bands.
