Surface color of raw lamb patties was measured using a portable spectrophotometer (CM‐600D; Konica Minolta Sensing Inc., Osaka, Japan) equipped with illuminant D65, 8 mm aperture, and 10° standard observer. Lightness (L* value), redness (a* value), and yellowness (b* value) parameters were recorded from two random spots from ten patties per mixture following standard procedures (AMSA, 2012).
