Effect of dietary blend of canola oil and palm oil on fatty acid composition, color and antioxidant profile of Biceps femoris muscle in goats

This study examined the effect of blend of 80% canola oil and 20% palm oil (BCPO) on lipid composition, antioxidant status, color and oxidative stability of Biceps femoris (BF) muscle in goats. Twenty-four bucks were randomly assigned to diets containing 0, 4 or 8% BCPO, fed for 14 weeks and slaughtered. Diet had no effect on glutathione peroxidase, catalase and superoxide dismutase activities. Goats fed 4% BCPO had higher (P<0.05) CLA cis-9 trans-11 while 8% BCPO had higher C18:3n-3 compared to other treatments. The 4 and 8% BCPO meat had lower (P<0.05) C14:0 and C15:0 and higher C22:5n-3 than did control goats. Dietary BCPO improved α and γ-tocopherol, redness and oxidative stability but did not affect total carotenoids and δ-tocopherol. Dietary BCPO enhanced beneficial muscle lipids without compromising color and lipid stability.
