Table 2: Rotated component matrix after factor analysis of concentrations found in chocolate. From the original variables, new combination variables can be formed for reasons of simplification, which are weighted by factors given in Table 2, after Varimax rotation (program: SPSS 19). Factor weights > 0,80 have been marked yellow for easier interpretation
