ResumoCALORIMETRY AND THERMOGRAVIMETRIC STUDY OF ALGAROBA [Prosopis juliflora (SW) D.C.]. Humidity and ash content of powder and bran of algaroba pods are important quality parameters for biological control during storage.The studies of humidity and ash content were carried out conventional and thermogravimetric methods.Different values were obtained by the various methods.The thermogravimetric method was faster and required less sample for the humidity and ash analyses of the powder and bran of algaroba pods.The differential scanning calorimetry curves of the powder and bran of algaroba pods, dryed at 55 o C, showed two peaks, one corresponding to the gelatinization of starch and the other to the vaporization of water.The samples dryed at 65, 75, 85, 95 and 105 o C showed one peak, corresponding to the vaporization of water.
