| Resumo: |
In this work the author puts in evidence a practical and at the same time rapid method for the determination of the cafein quantity in erva-mate, that may be utilized to perfection in food and industrial analyses or others that not demand scientific rigour. The author presents a description of the method and makes a comparison with the classical method of Grandval-Lajoux, showing that the differences between the one and the other are practically nil. In conclusion, the result of the three analyses of the same sample of erva-mate, made by the Grandval-Lajoux method are cited, show that the same differences appear as those shown between the rapid method suggested by the author and the classical method. In this case, the maximum difference was 0,06% and the minimum 0,01%.
