Summary. An examination has been made of the effect of sample dimensions on the objective assessment of meat tenderness. By adjusting shear‐force values‐measured at right angles to the muscle‐fibre axis‐to a sample cross‐section of 1 cm 2 at the proposed line of cleavage, variations in tenderness values within a sample are reduced to not more than ± 5 shear‐force units. Such variations represent approximately ± 1/2 unit in the mid‐region of a nine‐point sensory scale of tenderness. Through making such corrections to shear‐force values, it is anticipated that clearer indications of the effects of animal characteristics and carcass processing on tenderness within a single muscle will be possible. Conclusions concerning the mechanism of cleaving meat are drawn from the relationships that have been shown between sample dimensions and tenderness values.
