e 4 shows the results of sensory evaluation for the addition
of rice bran fiber and the replacement of pork back fat by
various vegetable oils in frankfurters. Each sample was evaluated
in terms of color, flavor, juiciness, tenderness and overall acceptability.
The control samples had the highest color scores, while
the vegetable oil samples had lower (P < 0.05) scores. The flavor,
tenderness, and juiciness scores were higher in the controls, but
there were no significant (P > 0.05) differences between the control
and the treatments. In contrast, the overall acceptability
scores were significantly different among the samples. Frankfurters
containing soybean oil (T5) had a lower (P < 0.05) overall
acceptability than the control and other samples and this may
be related with its high TBA value
