EFFECT OF A KAPPA CARRAGEENAN/LOCUST BEAN GUM MIXTURE ON BIND AND COOKING LOSS IN HIGH MANNURONATE ALGINATE RESTRUCTURED BEEF

Abstract

ABSTRACTRaw and cooked bind properties, cooking loss and pH were evaluated when adding three levels (0%, 0.25%, 0.50%) of a kappa carrageenan and locust bean gum mixture (C/LBG) to finely and coarsely ground high mannuronate alginate restructured beef. Treatments included variable levels of the following dry additives: Alginate (0.50%‐1.00%), calcium carbonate (0.10%‐0.20%) and glucono‐delta‐lactone (GDL, 0%‐0.80%). Raw breaking strength of finely ground formulations was increased by elevated alginate levels (P<0.05), but was not affected by C/LBG addition (P>0.05). The effect of alginate and C/LBG on cooked bind properties depended on whether finely or coarsely ground meat was used. Sensory evaluations of coarsely ground treatments suggest that sufficient raw and cooked bind was achieved using 0.50% alginate, 0.10% calcium carbonate and 0.60% GDL. Addition of 0.50% C/LBG and/or 0.75% alginate to coarsely ground formulations further reduced cooking loss (P<0.05) by relatively 13% and 17%, respectively. No interaction between C/LBG and alginate was found (P>0.05).
