Loss of characteristic meat flavor in dried beef, because of biochemical degradation of flavor-enhancing nucleotides, raises concern over the taste of meat products made in the home. Preservation effects on beef taste, using acetic acid and brine followed by dehydration were studied. Monosodium glutamate was added to the dried strips prior to cooking. The beefsteaks were subjected to three treatments: acetic acid, brine, while the control was untreated fresh beef. The samples were cut into strips then dried in a solar drier and an oven. Sensory attributes were evaluated for tenderness, juiciness, color, flavor and overall acceptability by an untrained sensory panel. Acetic acid, brine and control treatments were significantly different (P < 0.05) from fresh beef in tenderness, juiciness and color. Cooked beef flavor comparisons indicated that brine was better (P < 0.05) than acetic acid. Addition of monosodium glutamate to dried products significantly (P < 0.05) improved cooked beef flavor and acceptability.
