In all
samples redness decreased with increasing EPTs of meat, but red colour
(a⁎ values) of the WB-cooked meat faded very rapidly. Compared with
OH-cooked meat, significant increases (Pb0.05) of a⁎ value (range
7.78–9.09) were observed in WB-treated meat at EPTs (30–50 °C),
whereas decreases (Pb0.05) were seen at EPTs of 70 °C and 80 °C. The
higher a⁎ value is a well documented result of application of OH processing
on red muscles compared to conventional cooking (Shirsat et al.,
2004).
Chroma describes the depth of colour or the extent to which the
hue is diluted with black, and redness (a⁎) rather than yellowness
