Beef strip loins (n = 36) were enhanced with a sodium phosphate plus salt solution (PS); or with a calcium lactate solution (Ca) plus 1% or 2% beef broth (Br) plus natural flavoring (N) containing rosemary extract; or with 1% or 2% kappa carrageenan (Cr) plus N to determine effects of ingredients on color life, water-binding ability, and palatability traits. Enhancement with PS resulted in higher pH, higher pumped yields, greater water-binding ability, and higher tenderness and juiciness scores than enhancement with Ca (all p < 0.05). Enhancement with Ca resulted in less color deterioration, less metmyoglobin discoloration, higher L*, a*, and b* values, higher beef flavor intensity scores and lower off-flavor scores than enhancement with PS (all p < 0.05). Warner-Bratzler shear values did not differ among treatments. Steaks enhanced with Br had less color deterioration, less metmyoglobin discoloration, and higher V values than those enhanced with Cr (all p < 0.05). Pumped yields were not different between loins enhanced with Br or Cr. The N flavoring containing rosemary extract decreased (p < 0.05) discoloration. Enhancing beef longissimus with PS increased water-binding capacity and sensory tenderness traits, but reduced color stability and increased off-flavors, whereas Ca preserved color stability and enhanced flavor at the expense of pumped yields. The use of Br or Cr had no influence on tenderness or palatability traits. (C) 2003 Elsevier Ltd. All rights reserved.
