Fig. 4
presents the results of calculations of PO content in BF based on the
developed simple and multiple linear regression (MLR) equations
in relation to true adulteration level. The true concentration of
adulterant in BF was 5, 12, 18, 27, 32, and 38%. It may be observed
that for all DSC parameters, high coefficients of determination (r2)
were obtained, which indicates a high degree of linearity
