By performing a stepwise discriminant analysis, it is possible to identify and correctly classify 100% of the burgers using only two variables corresponding to the FA, C20:2n-6 and C18:1n-9, and the model is highly significant ( p < 0.0001 *; Wilks Lambda value: 0.00475) which is possible to see in Table 6 .
