Fibre-optic spectrophotometry of beef relative to sarcomere length (short communication)

H. J. Swatland

Abstract. Fibre-optic spectrophotometry of beef longissimus thoracis showed reflectance was correlated negatively with sarcomere length, reaching a maximum at 470 nm (r = −0.46, P < 0.025, n = 20) with mean sarcomere length 1.75 ± 0.15 mm. The beef had never been frozen and was extensively aged (30.5 ± 5.0 days). This conflicts with other relationships in attempts to predict tenderness from light scattering.
