The sample was triturated in particles aiming at to the attainment of one show homogeneizada. After that was given to beginning the characterization process biochemist of aa, where this if based on an experimental boarding of qualitative and quantitative character, developed through experimental tests.? Determination of the humidity text the humidity, generally, is determined by heating of the sample, the indirect gravimetrical method, where the sample is warm (placed in a greenhouse, with the purpose to evaporate the water and to the end to get the dehydrated sample) until reaching a constant mass and calculated for a difference enters the mass of the hidratada sample and of the dehydrated sample.? Determination of the leached ashes text the leached ashes text (inorgnica substance) was determined through the gravimetrical method direct. .
