dc.description.abstractPopularity of the microwave and a "fast-lane" lifestyle adopted by most Americans has prompted the development of frozen and shelf-stable microwaveable foods. Many foods such as vegetables, potatoes, and casseroles can be acceptably cooked from the raw state in a microwave oven. Consumer attempts to add meats to the menu that are cooked from the raw state or partially cooked such as, ground beef patties, steaks, chops, meat loaves and whole muscle meats result in decreased acceptability. This research was undertaken to identify starches and hydrocolloids with moisture-retention qualities that improve cook yield, evaporation loss and acceptability by the consumer, of pre-injected, precooked, whole muscle meat products. Beef shoulder clod roasts for Experiment I were injected with I % Firm-tex[], I % Pen Plus 10TM, 0.5% carrageenan and 0.25% Kelgum[] (xanthan gum). There were few differences in physical, chemical and sensory parameters. Firm-tex[] and Kelgum[] were selected for further study on the basis of numeric cook yield values and percent evaporation loss after reheating in the microwave. In Experiment 11, beef shoulder clod roasts were injected with I% Firm-tex[], 0.25 % Kelgum[], a 35%/65% and 65%/35% blend of Firm-tex[]/Kelgum[] and compared to a control. Cook yields favored the Firm-tex[], treatments of 35%/65% and 65%/35% Firm-tex/Kelgum[] blends with values of 94.46%, 93.5% and 92.8%, respectively. Because Firm-tex[] increased cook yields over control and Kelgum[], and did not have detrimental effects, it was selected for further testing in Experiment III. In Experiment III, top round and sirloin tip roasts were compared with and without 1% Firm-tex[] (starch). Cook yields and evaporation losses after reheating were not different. Firm-tex[] had little effect on shear values but did affect mushiness. Increased yields with Firm-tex[] without altering product quality could be useful in preparing a beef should clod roast for microwave application. Use of Firm-tex[] at levels of I% in sirloin tip and top round roasts did not appear to improve the processing or microwave reheating properties over conventional brine injection.en
