EFFECTS OF TRIMMING AND ADDED CONNECTIVE-TISSUE ON COMPOSITIONAL, PHYSICAL AND SENSORY PROPERTIES OF RESTRUCTURED, PRECOOKED BEEF ROASTS

Restructured beef roasts were prepared using trimmed (intermediate or extensive) and chunked (kidney plate or hand knife) beef shoulder clods with varying levels (0, 10, 20 or 30%) of added connective tissue (flaked with ComitrolR). Intact beef top rounds (control) and all restructured roasts were water cooked to 62.8°C internal temperature. Increasing connective tissue increased (P<0.05) tenderness and fat of restructured products with no deleterious effect (P>0.05) on product bind. Addition of 30% connective tissue decreased (P<0.05) juiciness and overall acceptability of the products; however, products with addition of 10% or 20% connective tissue were acceptable. Sensory data indicated restructured roasts were as acceptable as intact top rounds. Copyright © 1990, Wiley Blackwell. All rights reserved
