Comparative Study of the Physicochemical, Functional, Thermal, and Rheological Properties of Pretreated Flours From <i>Dioscorea alata</i> and <i>Dioscorea rotundata</i>. [PDF]

open access: yesFood Sci Nutr
Pretreatments help improve flour quality. The increase in solubility and dispersibility is greater in D. rotundata. D. alata flours are more resistant to shear than D. rotundata flours. All flours degrade after 200°C. D. alata flours are more elastic while D. rotundata flours are more viscous.
