Abstract

Impacts of cooking times (steaming and cooking on embers) on some physico-functional parameters of yam (D. bulbifera) flours cv Dougou-won were determined during 10, 20 and 30 min. Results showed that steaming and cooking on embers increased significantly (P <0.05) the dispersibility (D), water absorption capacity (WAC), paste clarity (PC), water solubility index (WSI), swelling power (SP), least gelation capacity (LGC) and solubility (S) but decreased significantly (P <0.05) foam capacity (FC), wettability (W) and foam stability (FS) of flours (D. bulbifera) cv Dougou-won. Steaming increased significantly (P <0.05) oils absorption capacity (OAC) and bulk density (BD). However, cooking on embers decreased significantly (P <0.05) oils absorption capacity (OAC) but not affected significantly (P <0.05) bulk density (BD). The steaming time (30 min) is recommended to considerably influence the physico-functional parameters of the yam (D. bulbifera) flours cv Dougou-won.
