Conteúdo: | The use of sorghum in human nutrition has been expanded due to its nutritional composition and its functional potential. Extrusion has been used to improve the quality of sorghum. The aim of this work was to assess the effect of extrusion in the nutritional composition, phenolic compounds content of two sorghum, and characterize the profile of chemical constituents by paper spray mass spectrometry (PS-MS). Extrusion increased the carbohydrate and fiber contents and reduced moisture, lipids and ashes, and enabling a higher degree of liberation of phenolic compounds and antioxidant activity. The fingerprint obtained in both ionization modes had been influenced by extrusion, allowing for a greater compounds? identification on the extruded samples. The analysis of sorghum samples? main components made distinguishing of the main constituents possible, as well as highlighted the extrusion effect and the influence of the genotypes. This study demonstrated that extrusion enabling a higher liberation of phenolic compounds, which were identified by the PS-MS technique.
