Table 1.

Parameters obtained for the construction of the primary model equations. W1, W2, W3 and W4 represent, respectively, the fatty acids region (3000–2800 cm⁻¹), the amides region (1800–1500 cm⁻¹), the mixed region from 1500 to 1200 cm⁻¹ and the carbohydrates one from 1200 to 900 cm⁻¹. WS stands for whole spectrum.
