As the color differences among the prototype crackers were
distinct, difference in mean color score was significant.
Increase in the HSR content from 1.25% to 5% in the mixture
decreased the color score. About 77% of color acceptability
scores were in the ‘‘liking’’ range (5.0–7.0) of the 7-point hedonic
scale, indicating that product color within the range of
samples evaluated in this test is not likely to be a hindrance
to product acceptability.
Difference for taste was significant with mean scores ranging
from 5.61 to 3.5 across the treatments. Where, samples
incorporated with 1.25 as well as 2.5% HSR had better effects
on taste compared with other treatments and control formula.
Crackers crispness score ranged from 3.43 for control to 5.32
for 2.5% HSR crackers. The incorporation of HSR improves
the crispiness of HSR containing crackers compared to the
control where 1.25% and 2.50% HSR crackers scored with
higher intense values followed by 3.75% and 5% HSR
crackers.
A marked similarity was reported for odor where cracker
recipes containing 1.25% and 2.5% HSR scored higher than
crackers with increased amount of HSR and control as well.
For appearance cracker snacks which contained HSR received
lower scores compared to control crackers. The surface characteristics
of such crackers were negatively affected by the HSR
addition.
