Fibres as an additive for oil reduction in deep fat fried poori

Models capable of predicting the moisture and oil content as well as overall acceptability (OAA) of poori, prepared from wheat flour incorporated with wheat bran and oat bran were developed using response surface methodology. Central composite rotatable design with two independent variables (wheat bran and oat bran) at five levels (wheat bran, 3-9 g/100 g wheat flour and oat bran 6-12 g/100 g wheat flour) was used to optimize the bran level. Results showed that oat bran had significant (p ≤ 0.05) positive effect on moisture retention and negative effect on oil absorption, while wheat bran had reverse effect. Based on compromise optimization, it was recommended to incorporate 3.0 g wheat bran and 11.0 g oat bran (per 100 g wheat flour) for making fibre rich (4.2% total dietary fibre, 1.3% soluble dietary fibre) poori with lower oil content (20% less as control) and optimum acceptability (88.6).
