Abstract :
Eighteen Barbarine lambs were assigned during 77 days to three dietary treatments (n = 6): control, oat hay ad libitum and 400 g of concentrate; QS60 and the QS90 control diet supplemented with 60 mg and 90 mg Quillaja saponaria (QS) bark extract/kg dry matter, respectively. The analysis of pre-frozen longissimus dorsi muscle showed that the QS90 treatment reduced meat redness (a*) and saturation (C*) measured after 2 h of blooming. It also reduced the rate of decrease in a* values (P = 0.02) during 14 days of refrigerated storage. Supplementation with QS extended meat colour stability by reducing (P < 0.05) the rate of increase in hue angle (H*) values. Neither the rate of metmyoglobin accumulation at the meat surface nor lipid peroxidation over storage duration differed between treatments. The overall meat volatile compound profile was similar between the groups. We conclude that supplementing QS affects meat colour development at the meat surface and extends its stability without producing detrimental effects on meat volatile compounds.
