Texture 1. Mechanical Measurements Hardness – The force required to obtain a given deformation. Cohesiveness – Strength of the bonds which holds a food together. Adhesiveness – Attraction to another surface Fracturability - Ease with which something shatters Viscosity – Rate of flow per unit of force or time.Texture 1.
