Parameter |
Sensorial and Instrumental Definition |
Hardness |
Force required to compress a food between the molars |
Cohesiveness |
The strength of the internal bonds making up the food |
Chewiness |
The energy required to chew a solid food until it is ready for swallowing,
Chewiness = Hardness x Cohesiveness x Elasticity |
Gumminess |
The energy required to disintegrate a semisolid food so that it is ready for swallowing, Gumminess = Hardness x Cohesiveness |
Springiness |
The spring back is measured at the down stroke of the second compression, so the wait time between two strokes can be relatively important. Expressing springiness as a ratio of its original height, comparisons can be made between a broader set of samples and products. |
Resilience |
Resilience is measured on the withdrawal of the first penetration, before the waiting period is started. Resilience can be measured with a single compression, however, the withdrawal speed must be the same as the compression speed. |
