Abstract

Tandoori roti, a wheat-based Indian traditional product, prepared by sheeting the whole wheat flour dough into 2±3 mm thickness and 15±20 cm diameter, is baked in a special type of oven known as a `tandoor'. Six commercially-grown wheat varieties were evaluated for their physico-chemical characteristics and carbohydrate profiles. Rheological studies indicated a significant difference among the varieties, especially between varieties having good (Cpan-3004: Sensory score, 28.27) and poor (PBW-138: Sensory score,23.22) tandoori roti-making quality. The peak viscosity correlated well with the damaged starch content. The carbohydrate profiles of wheats indicated that the water soluble polysaccharides and destarchi®ed flour fractions contained mainly arabinose and xylose along with glucose. The contents of arabinose and xylose were higher in the fractions of the variety having good tandoori roti-making quality.
