SUMMARY A portable EEL reflectometer was modified to measure the variations in the brightness of pig meat. The instrument was calibrated spectrophotometrically with reference to the luminous reflectance of standardized materials and selected meat samples. A very satisfactory level of agreement between the instrument and the visual assessment of muscle paleness was found in an investigation involving 251 pigs.
