2.12. Sensory test
The sensory test was conducted on about thirty men and women. The
ohmically heated and retort-heated samples, each 2.0±0.1g, were placed
on separate trays and the subjects evaluated them in terms of appearance,
flavor, taste, tenderness, flavor in mouth, and comprehensive evaluation
(six items) on a five-point scale (−2 to 2). As for comprehensive
evaluation, a two-sample preference test was also conducted.
2.13. Statistical analysis
The results were expressed as average ± standard deviation, and
a t-test was used for determining statistical significance. Microsoft
Excel was used for this analysis.
