Abstract
A low‐fat (12%) high‐added water (27%) bologna was formulated with mechanically deboned turkey meat (MDTM) and either carrageenan (0.5%), milk protein (2%), isolated soy protein (2%), or starch (2%). Cooking loss, purge loss during storage, cooked product bind, sensory characteristics, and batter viscosity were evaluated. Starch added late in the chopping process was the most effective in reducing cooking loss as well as decreasing (P < 0.05) purge loss during storage (both refrigerated and frozen storage). Cooked product hardness was increased (P < 0.05) by all test ingredients, except starch and kappa carrageenan added late in the chopping process. Kappa carrageenan incorporated before chopping significantly (P < 0.05) increased cooked product bind. Overall acceptability (sensory analysis) scores were higher (P < 0.05) when milk protein, isolated soy protein and starch were added during chopping, compared to their addition prior to chopping. However, this order of addition effect was not observed for either of the carrageenan treatments.
