3. Results and discussion
The performance parameters of the proposed method were adequate for the detection and quantification of the bioactive amines in both egg albumen and yolk.
The regression equations and the coefficient of determination (R
) for the analyses of amines added to albumen and yolk, obtained in the evaluation of linearity in the range from 0.7 to 22.4 mg kg
,are represented in Table 1. The values indicate that the model is adequate, given that the coefficient of determination (R
2
) of the analytical curves was greater than 0.99, which is evidence of a fitofthedatato the regression line. According to the criteria of the European and Brazilian legislations, values higher than 0.99 are recommended for the linearity tests [13,22]. This parameter allows for the estimation of quality for the obtained curve, as the closer its value is to 1.0, the lower the dispersion of the set of experimental points and the smaller the uncertainty of the estimated coefficients of regression [26].
