Steam pressure and rotation speed effects on process yield and quality attributes of double drum-dried sweet corn pulp was evaluated by response surface methodology. Models of second degree polynomial equations were developed for variables related to process yield, protein nutritive value and product sensory profile which were statistically significant in the range of 0.23 to 23% for average value. PER and apparent protein digestibility was 2.2 and 75.2%, respectively. An average reduction of 15.4% and 6.5% with respect to raw material was determined for PER and protein digestibility, respectively. Combination of low steam pressure (around 3.65 kgf/cm2) and high rotation speed (corresponding to 60 sec of drying time) resulted in higher yield and product with good nutritional and sensory qualities.
