3.1.2. Color evaluations
The color evaluation of addition of GRF at three levels in ground
pork patties are shown in Table 2. There was no significant difference
in L* values among all treatments except 5% GRF (P > 0.05).
And a* values did not significantly differ while supplement of GRF
in pork patties (P > 0.05). Significantly lower b* values were found
in 1% and 3% GRF samples compared with control and 5% addition
(P < 0.05). Yi et al. (2012) reported that color of beef patties added
with GRF were not different significantly. The different results may
related to the different materials, or processing methods.
