Valida??o de uma metodologia analítica para determina??o de cálcio em produtos cárneos

摘要

The aim of this study was to validate an optimization of a traditional methodology of calcium determination in meat products. In Brazil, the method of calcium determination described by the Ministério da Agricultura Pecuária e Abastecimento uses asbesto fibers in a stage of filtration, which is toxic. In the methodology proposed in this work, we replaced these asbestos fibers with quantitative filter paper. To evaluate the analytical methodology proposed, we considered: linearity, sensitivity, detection, quantification limits, precision, accuracy, specificity, robustness, and inaccuracy of measurements. The optimized analytical method proposed in this work proved sensible, accurate, exact, robust, and linear. Considering the determination of the calcium content in meat products was considered suitable.
