Table 5 List of the main mechanical features related to texture profiling, relative characteristics and characteristic of berry influencing each feature.
Mechanical features | General description | Unit | Acronym | Berry texture characteristics |
|---|---|---|---|---|
Maximum force | Maximum force value recorded over the probe’s travel | N | F Max | Skin and external tissues firmness/fracturability |
Maximum force deformation/strain | Computation of the maximum force associated with the curve on its whole length | % | Def F Max | Berry pulp consistency/firmness |
Minimum force | Minimum force value recorded over the probe’s travel | N | F min | Berry pulp consistency/firmness |
Minimum force deformation/strain | Computation of the minimum force associated with the curve on its whole length | % | Def F min | Berry pulp consistency/firmness |
Final force | Force measured at the end of the probe’s travel | N | F Fin | Whole berry consistency/firmness |
Area | Area underlying the mechanical profile | Nmm | Area | Whole berry consistency/firmness |
Gradient | Young’s modulus or elasticity modulus, computed as ratio between stress and strain | MPa | Gradient | Skin and outer tissue layers elasticity |
