    To validate the method for obtaining crude fat from food samples (cereals, dairy and meat) the AOAC Official Method 2003.06 was used and showed variations in repeatability and reproducibility. The critical value of repeatability (Lr) and reproducibility (LR) were performed for both analysts of study and its results were for cereals and their derivatives Lr=0,18; 0,31 LR=0,22; dairy and their derivatives Lr= 0,18; 0,82 LR= 0,68; meat and their derivatives Lr= 0,35; 0,54 LR= 0,38. These values show a high fidelity of the values of the analysis method. The accuracy values of the three matrices used (cereals, dairy, meat with their derivatives) were within the range of standard deviation of the sample reference previously validated. Uncertainty values for the products analyzed were for cereals and their derivatives: ±0.16g/100g; dairy and their derivatives: ±0.50 g/100g; meat and their derivatives: ±0.274g/100g.
