Springiness (ratio) | 0.80 | 0.75 | 0.73 | 0.62 | 0.68 | 0.032 | NS |
Cohesiveness | 0.47a | 0.25b | 0.25b | 0.24b | 0.26b | 0.025 | 0.000 |
Gumminess (kg) | 6.32a | 0.90b | 0.72b | 0.56b | 1.06b | 0.693 | 0.007 |

Control was prepared with only porcine myofibrillar protein (60 mg/mL), and porcine myofibrillar protein-gelatin mixtures were formulated with porcine myofibrillar protein and each gelatin (9:1 ratio) at the same protein concentration.
Means sharing different letters within a row are significantly different (p<0.05).
NS, non-significance (p≥0.05).
