Abstract
Flank muscles from pre-slaughter adrenaline-treated animals were significantly darker in color and presented higher pH values than untreated animals. Color scores and pH values of the flank muscles were related to pH values of the longissimus dorsi muscle. The increase in color intensity of lamb muscle, as measured by a subjective panel, apparently was influenced more by changes in muscle consistency due to higher pH than by quantity of pigment.
