Millet [Pennisetum glaucum (L.) R. Br.] is a cereal rich in bioactive compounds that are mainly present in the bran fraction. However, bran is an underused resource and green technologies could be an interesting alternative to add value to this product, improving its bioactives recovery. In this study two techniques were used, thermoplastic extrusion (TE) as a pre-treatment and supercritical fluid extraction (SFE). The objective was to evaluate the effect of TE on the total phenolic content (TPC) in the extracts of millet bran (MB) and extruded millet bran (EMB) obtained by SFE with different conditions of pressure (P 10-30 MPa), temperature (T 40-60 °C) and percentage of cosolvent (C 5 and 15% ethanol). The bran was obtained from millet grains donated by Atto Sementes, cleaned in a mechanical separator, decorticated in a rice mill, and finally grounded in a hammer mill. Extrusion was carried out in a 19/20 DN single-screw laboratory extruder and extractions were carried out using the MV 10 ASFE system equipped with a 25 cm3 extraction cell. The highest yield of TPC, 21.34 mg GAE/g extract, was obtained for EMB (40 °C, 10 MPa and 15%). On the other hand, MB showed the lowest yield (4.70 mg GAE/g extract) at 50 °C, 10 MPa and 5%. Extrusion had a positive effect leading to a 36.65% increase in TPC yield compared to non-extruded samples. For EMB, the variables (P) and (C) alone had a positive effect, while the opposite was observed for (T). On the other hand, for MB all the variables exerted a positive effect. This study shows that the increase in TPC can be related to the modification of the bran matrix under extrusion conditions of high temperature, pressure, and shear which were more significant when extracted using 40 °C, 10 MPa and 15% co-solvent.
