Results of this study indicated that flours with carriers presented better fluidity (lower values in angle of repose and slide), and storage properties (lower moisture content and higher Tg values) as compared to flours without carrier. Flours with MD and MD/b-CD had higher antioxidant components retention rates than flours with b-CD and without carrier. MD could be a better carrier in producing higher quality purple sweet potato flour than b-CD and MD/b-CD
