Techniques for measuring mechanical resonance, vibration transmissibility, pulse propagation velocity, and the resilience or rebound characteristics of solid food commodities are reviewed. Emphasis is placed upon measurements of the dynamic elastic properties of foods and changes in these properties as food products lose their stiffness, rigidity, or firmness. Correlations of certain elastic properties with product quality, especially texture, are presented, and a number of nondestructive dynamic methods for sorting food commodities are described.
