Area of Science:

  • Food Science
  • Meat Science
  • Optical Physics

Background:

  • Beef tenderness is a critical quality attribute for consumers.
  • Predicting beef tenderness requires understanding muscle's physical characteristics.
  • Current methods for assessing tenderness can be destructive or time-consuming.

Purpose of the Study:

  • To evaluate a novel 2D optical reflectance imaging method for predicting beef tenderness.
  • To correlate optical parameters derived from reflectance images with Warner-Bratzler shear force (WBSF).

Main Methods:

  • Acquired 2D optical reflectance images of beef muscles under point incident light.
  • Extracted five parameters, including scattering intensity and fitted contour parameters (q, B).
  • Applied the method to 336 beef samples with varied genetics, suspension, and aging, measuring WBSF for tenderness evaluation.

Main Results:

  • Scattering intensity at 1-day correlated with 10-day WBSF (R²=0.50) in M. longissimus dorsi.
  • Parameter q at 1-day correlated with 10-day WBSF (R²=0.46) in M. psoas major.
  • Optical parameters provided valuable information on physical characteristics related to beef tenderness.

Conclusions:

  • 2D optical reflectance imaging is a promising non-destructive method for predicting beef tenderness.
  • The derived optical parameters offer insights into meat's physical properties influencing tenderness.
  • This technique can aid in quality control and selection processes in the beef industry.
