Abstract
ABSTRACTThe effects of added antioxidants on restructured combination (50:50) beef‐pork steaks were studied. Steaks were formulated to contain 20% fat and 0.75% salt. Antioxidants used at a 0.02% level (based on fat content of meat) were butylated hydroxyanisole (BHA), tertiary butyl hydroquinone (TBHQ), and a combination of BHA and TBHQ. Cooked steaks were evaluated for sensory properties and overall acceptability, initially and after 4, 8, 12, 16, an 20 wk of freezer storage. Steaks were also evaluated after the various storage times for 2‐thiobarbituric acid (TBA) values, subjective color by panel evaluation, objective color with the Hunter color difference meter, tensile strength, shear value and cooking loss. Flavor and overall acceptability were significantly better in treated samples as compared to control samples. BHA was more effective in protecting color and TBHQ was more effective in protecting flavor (P<0.05). All treated samples showed lower TBA values than control samples (P<0.05).
