The effects of chemical modification on the pasting properties of a high-protein (Hinoat) and medium- protein (Rodney) oat flour were studied. Both acetylation and hydroxyalkylation resulted in a shift to lower gelatinization temperatures and higher viscosities than were exhibited by the parent flours. Oxidation by hypochlorite resulted in products having pastes more stable to shear and of a smoother consistency. These derivatives were resistant to retrogradation but were opaque and buff-colored. The carbamoylethyl ether of Hinoat flour had a lower peak viscosity than the corresponding wheat flour derivative, but a similar setback viscosity. Again the oat pastes were buff-colored and opaque. These results are discussed from the viewpoint of potential low-cost food and industrial applications.
