- Influence of post-harvest thermal dehydration on antioxidant quality of 26 orange-fleshed sweet potato genotypes Mariana Emy Haneda Ferrarini Letícia Silva Pereira Basílio Pablo Forlan Vargas Matheus Antonio Filiol Belin Anna Carolina Abreu Francisco e Silva Giuseppina Pace Pereira Lima Agrociencias flour provitamin A biofortification bioactive compounds In this study, we characterized the biochemical profile of orange-fleshed sweet potato genotypes for flour production. Flours from 26 sweet potato genotypes were evaluated, including 'Beauregard', a commercial genotype, used as a control. Two drying temperatures were analyzed in a forced air circulation oven: 50°C and 70°C. The content of total carotenoids, total phenolic compounds, and antioxidant capacity were analyzed by the DPPH, ABTS, and FRAP methods. Contents of total carotenoids increased in most of the genotypes studied after drying (mainly sweet potatoes with more intense orange flesh) and some genotypes showed great potential for antioxidant compounds. In the analyzes carried out, drying did not show a negative influence on the amount of bioactive compounds, showing good results in nutrient retention. '21-01', '21-27', '22-24', '29-19', '56-27', '60-25' stood out for containing higher levels of bioactive compounds than 'Beauregard'. 50°C was the best temperature to maintain the bioactive content in dried sweet potatoes. These genotypes should be better studied regarding the content of these pigments, since they can be important for nutrition studies, aiming to increase the content of pro-vitamin A supplied as flour. 2022 artículo científico 1665-0204 https://www.redalyc.org/articulo.oa?id=81371861007 https://www.redalyc.org/journal/813/81371861007/ https://www.redalyc.org/journal/813/81371861007/html/ https://www.redalyc.org/journal/813/81371861007/81371861007.epub https://www.redalyc.org/journal/813/81371861007/movil en http://www.redalyc.org/revista.oa?id=813 Revista Iberoamericana de Tecnología Postcosecha application/pdf Asociación Iberoamericana de Tecnología Postcosecha, S.C.
