title: Effects of vascular infusion with a solution of saccharides, sodium chloride, and phosphates with or without vitamin C on carcass traits, Warner-Bratzler shear force, flavor-profile, and descriptive-attribute characteristics of steaks and ground beef from Charolais cattle.
abstract: Two groups of 18 grain-finished steers were utilized. Nine from one group were infused via the carotid artery immediately after jugular vein exsanguination with an aqueous solution containing saccharides, NaCl, and phosphates (MPSC; MPSC, Inc., Eden Prairie, MN, USA). Nine steers served as non-infused controls (CON). An additional 18 steers were infused with either MPSC (n=9) or MPSC plus 1000 ppm vitamin C (MPSC+C, n=9) solutions. Steers infused with MPSC had higher dressing percentages and organ weights than CON steers. Vascular infusion with MPSC had no effects on USDA yield or quality grade traits, descriptive-attribute sensory panel evaluations, or Warner-Bratzler shear force of longissimus lumborum and semitendinosus muscles. Vascular infusion with MPSC resulted in some significant, but inconsistent effects on flavor-profile characteristics of cooked beef. The addition of vitamin C to the MPSC solution did not provide any benefit.
