Mass transfer kinetics of moisture outflow and oil uptake during deep fat frying of snack food prepared from a blend of chickpea
flour and modified starch have been investigated. The effect of frying temperature and pre-fry drying has also been studied. The
results indicated that an increase in the temperature of frying (150–2001C) causedan increase in mass transfer coefficient for
moisture (0.045–0.096 s1) as well as for oil (0.056–0.082 s1). Pre-fry drying also had a significant effect on the deep fat frying. As
the pre-fry drying time was increased (0–90 min) before frying at 1751C, it resultedin a decrease in kinetic coefficient for moisture
transfer (0.056–0.039 s1) as well as in kinetic coefficient for oil transfer (0.063–0.035 s1). Basedon the kinetics andsensory data,
the optimum pre-fry drying and frying times were 40 min and 45 s, respectively, which resulted in 54% reduction in the oil content of
the friedprod uct, without compromising on the sensory quality characteristics.
