L∗ value is correlated with WHC of pork LD muscle (Warriss
and Brown 1987; van Laack and others 1994; Joo and others 1995).
During the process of rigor mortis, some muscle proteins are
denatured, which increased free water and juice loss, and further
changed the surface reflection properties of meat.Our results show
again that change in L∗ values is associated with WHC in LD
during postmortem aging.
Brewer and McKeith (1999) reported that color is an important
factor in predicting consumer self-reported purchase intent of
chilled, fresh pork. Zhu and Brewer (1999) reported that instrumental
color characteristics (L∗, a∗, b∗) were highly correlated with
visual redness of fresh meat. Therefore, consumers were visually
perceptive to the instrumental color differences
