This paper describes the influence of pH on the viscosity or consistency properties of Habanero (D. rotundata) yam starch. Initial viscosity of starch slurries varied from 73.5° to 75.3° C. Except for a sample at pH 3.00, yam starch was stable when cooked at 50° C for 1 hour. The strength of the starch was lower when cooked at 95° C. At pH 3.00 and after reaching 95° C the starch thins down to zero viscosity and never retrogrades. The correlation coefficients between shear press of starch gels and amylographic measurements were high and significant at the 1% level.
