MS_FTIR_figure 4 and its associated data

Figure 4. Hierarchical cluster analysis of the s-FTIRM images for WPC 80-emulsified milk fat globules after gastric and small intestinal digestion, showing distinctive clusters (numbered 1 to 4, each assigned by different colour). Average spectrum extracted from the individual cluster that highlights regions rich in either lipid or the digested products was shown in the left panel. The bottom panels show the scores plot and the corresponding loadings plot from principal component analysis of the average absorbance spectrum.
