3.4. Sensory acceptance
The results of the acceptance test with 63 panelists are shown in
Table 4. No significant difference (p N 0.05) was found among samples,
thus gamma radiation did not damage the sensory characteristics of the
meat.
Park et al. (2010) conducted sensory evaluation of vacuum-packed
hamburgers irradiated with doses of 0, 5, 10, 15 and 20 kGy followed
by accelerated storage at 30 °C for 10 days. They found no difference
(p N 0.05) in color, chewiness and flavor for samples irradiated with gamma rays at 10.0 kGy and overall qualitywhen using 5 kGy. Similarly,
Miyagusku, Chen, Leitão, and Baffa (2003) evaluated slices of chicken
breast without skin or bone and concluded that 3.0 kGy irradiation increases
shelf life from 5 to 22 days without modifying the sensory
attributes.
