Abstract
The influence of some food ingredients commonly used in bread making on various characteristics of instant tanier (Xantohosoma sp.) flakes, wheat flour, and a mixture of 15% tanier flakes, and 85% wheat flour (15-85 mixture) was determined. Pasting measurements, taken us in~ the Brabender Amylograph-Viscograph, were higher for samples contaimng wheat flour. Tanier starch from flakes was stronger than wheat starch. Both starches showed good stability while cooking for 1 hour at 93 and at 50° C. A peak viscosity was observed in some samples while cooling to 50° C. In tanier flakes, ingredients tended to decrease pasting measurements while in wheat flour they tended to increase them. Pasting properties of the 15-85 mixture followed the same pattern of wheat flour, but the presence of tanier flakes tended to lower the values. Light reflectance measured after amylography (paste clarity) was higher for wheat flour while shear press (gel texture) tended to be higher for the 15-85 mixture.
