The breaking strength of the fried ribb on snack (frying
temperature 1751C andfry ing time 45 s) for different
moisture contents after pre-fry drying is presented in
Fig. 9. It was observedtha t the breaking strength, which
reflects the hardness of the fried snack, increased at a
slower rate in the beginning andat a higher rate later as
the moisture content was reduced up to 0.125 kg/kg
(beyond this the hardness didnot change much).
The sensory scores of the dried ribbon snacks (for
different times from 0 to 90 min) that were fried
at 1751 C for 45 s are shown in Fig. 11. All the attributes
namely appearance, colour, crispness, taste andoveral l
acceptability were compared with those of control
sample using t-test for comparison of two means at
Po 0.05. The control sample was the fried snack
prepared without pre-fry drying. The results indicated
that up to 60 min of pre-fry drying of extruded ribbons,
all the attributes except appearance of the fried product
were not different (Po 0.05) from the control sample.
The optimum conditions were derived taking into
account the sensory data.
