Thaw loss % | Drip loss % | Cooking loss % | WHC (%) | pH | |
Control | 12.6a ± 0.11 | 47.27a±0.38 | 69.86c ± 0.06 | 6.15a ± 0.04 | |
4℃ | 6.13 ± 0.25 | 11.42a ± 0.23 | 49.59a ± 0.42 | 74.73b ± 0.27 | 5.72a ± 0.04 |
40℃ | 6.54 ± 0.25 | 5.66b ± 0.23 | 41.27c ± 0.42 | 78.58a ± 0.27 | 5.48b ± 0.04 |
Tap water | 6.57 ± 0.25 | 4.90b ± 0.23 | 47.92b ± 0.42 | 73.77c ± 0.27 | 5.39b ± 0.04 |
Level of Significance | NS | ** | ** | ** | * |
Means with different superscripts in each column are significantly different (**p<0.01 and *p<0.05). NS was not significantly different.
