Abstract: | Studies were carried out to determine the effect of baking, in different types of oven such as an earthen tendoor, a gas tandoor, an electric oven and a heated plate, on the physico-chemical and quality characteristics of tandoori roti. The studies indicated that the extent of gelatinization of starch varied depending on the type of oven used and was found to be 74.6, 78.4, 90.7 and 88.4% in roties baked in an earthen tandoor, a gas tandoor, an electric oven and a heated plate respectively. The pasting characteristics of starch, separated from the tandoori roti sample and measured using a Rapid Visco Analyzer, indicated the highest peak viscosity (36 SNU) for tandoori roti baked in an earthen tandoor and the lowest (25 SNU) for that baked in an electric oven. The concentration of high molecular weight proteins was lower in roti baked in an earthen tandoor and a gas tandoor, indicating greater dissociation of high molecular weight proteins during baking in such ovens. The sensory texture, taste and flavour of roti baked in an earthern tandoor was found to be superior to those baked in other types of ovens. |
