Resumo

The aim of this work was to evaluate the thermal and kinetic behavior of white lupin (Lupinus albus) oil obtained from its seeds. White lupin is a seed from the Lupinus albus species, and it presents physicochemical and physiological functional properties and is rich in fiber, protein, and lipids with a great application potential. Oil was extracted from the seeds, and its fatty acid profile indicates predominantly monounsaturated fatty acids (similar to 65%). Thermo-gravimetry, derivative thermo-gravimetry, and differential scanning calorimetry (DSC) were used to characterize the thermal behavior of the oil fraction at high temperatures, showing a good thermal stability between 222 and 230 A degrees C and a large heat delivery at T = 400 A degrees C. Additionally, DSC was performed from 25 to -60 A degrees C, in which the crystallization behavior was verified. The kinetic behavior of the thermal decomposition was evaluated from several beta values and mass samples (5 and 20 mg) under nitrogen and oxygen atmospheres to comparisons of the data. (AU)
