Abstract

We recently found that optical scattering coefficients of beef muscle can be used as a predictor for beef tenderness. However, it is still not clear what specific muscle properties are responsible for optical scattering. As an effort to answer these questions, we conducted several controlled experiments in which we studied the changes of scattering coefficient with muscle sarcomere length and ageing time. The optical scattering coefficient of beef muscles were measured based on a diffusive fitting of spatially resolved reflectance measurements. Samples with different sarcomere lengths were obtained by proper carcass hanging strategies. Our results indicated that muscle scattering coefficient increased with ageing time and sarcomere length. These experimental observations can be qualitatively explained based on previous research on single muscle scattering. This study suggests that muscle structural properties have significant impact on muscle optical scattering coefficients.
