In this study, the descriptive sensory attributes, oral processing characteristics of and subjective satiety responses for extrusion cooked cassava-soy porridge with wheat bran at 0, 100 and 200 g/kg addition levels were determined. Fifteen subjects (23–47 years, mean BMI 22.6 kg/m2) consumed 250 g of each porridge type over 8 breakfast meals while being video recorded. Oral exposure time and number of bites, and eating and bite rates were determined. Subjects rated hunger, fullness and desire to eat before meal, post meal and periodically over 3 h post consumption. A separate panel profiled the descriptive sensory attributes of the porridges. The addition of wheat bran increased visually perceived viscosity and presence of visible particles. The porridge with 200 g/kg wheat bran was eaten with more bites and at a slower rate thus, having longer oro-sensory exposure. Also, the porridge with 200 g/kg wheat bran led to greater reduction in subjective reported hunger compared to the other porridges. Wheat bran as a source of dietary fibre has the potential to be incorporated as a component of extruded starch-rich foods to produce instant products which can promote satiety.
