- Bioactive compounds from brewer’s spent grain: phenolic compounds, fatty acids and in vitro antioxidant capacity Aline da Rosa Almeida Márcia Regina Ferreira Geraldo Leomara Floriano Ribeiro Marcos Vieira Silva Matheus Vinicius de Oliveira Brisola Maciel Charles Windson Isidoro Haminiuk Ingeniería By products flavonoids antioxidant brewer's spent grain Brewer's spent grain (BSG) was characterized by physicochemical, total phenolic compound and flavonoids contents. Antioxidant activity was evaluated by four different assays. The chromatographic analyses were used to quantify the phenolic compounds and the fatty acids in BSG. Ethanolic extracts were tested to evaluate antibacterial activity. The higher concentration of total phenolic compounds for BSG was obtained in the extraction with ethanol 20%. BSG showed an antioxid ant potential for all tests evaluated. In the case of chromatographic analysis, phenolic acids and flavonoids, such as syringic acid and catechin, respectively, were detected in high quantities. Regarding to the fatty acids pr ofile, polyunsaturated fatty acids, such as linoleic and oleic acids, were found in significant amounts. No antiba cterial activity was reported for bacterial cultures and concentrations tested. BSG may be considered a protein source, rich in fiber, polyunsaturated fatty acids and bioactive compounds with antioxidant potential. 2017 artículo científico 1806-2563 https://www.redalyc.org/articulo.oa?id=303252892003 https://www.redalyc.org/journal/3032/303252892003/ https://www.redalyc.org/journal/3032/303252892003/html/ https://www.redalyc.org/journal/3032/303252892003/303252892003.epub https://www.redalyc.org/journal/3032/303252892003/movil en http://www.redalyc.org/revista.oa?id=3032 Acta Scientiarum.
