Abstract
An optimized formulation was developed for preparation of parotta, a South Indian bakery product made from wheat flour, salt, sugar, egg, oil and water. This was modelled by response surface methodology (RSM) by using a Central Composite Rotatable Design (CCRD) with 5 independent variables (water, salt, sugar, egg and oil), each at 5 different levels. The dependent variable or response measured for each treatment was the overall sensory quality score. The response surfaces and contour maps showing the interactions of ingredients indicated that the quality of parotta could be optimized by decreasing the percentage of water, increasing the percentage of oil and retaining salt, sugar and egg concn. within a narrow range of variation from mean levels. According to the RSM, the actual comparative amounts of ingredients at the max. estimated overall sensory quality score of 95.9 were: wheat flour 100; water 56.3; salt 1.0; sugar 0.8, egg 9.6 and oil 16.6.
