Papadams, made from black gram (Phaseolus mungo) and largely manufactu
red on cottage scale are popular in the Indian dietary. Escalating pri
ces of black gram coupled with abundant availability of tapioca flour
at almost 1/8th the price of black gram prompted the study of papadam
characteristics using blends of black gram and tapioca flour. Tapioca
flour up to 25% substitution did not alter the sensory attributes. How
ever, the expansibility of the product decreased on addition of tapioc
a flour; a fact which could be overcome by using carboxymethyl cellulo
se (CMC) at 3% level of black gram flour. This decreased the oil conte
nt to 19.7% and also increased the expansibility to 5.539%.
