Bg. Lyon et Ce. Lyon, EFFECTS OF WATER-COOKING IN HEAT-SEALED BAGS VERSUS CONVEYOR-BELT GRILLING ON YIELD, MOISTURE, AND TEXTURE OF BROILER BREAST MEAT, Poultry science, 72(11), 1993, pp. 2157-2165
The sensory texture profile, shear values, yield, and moisture were de
termined for broiler breast muscle deboned at 2 or 24 h post-mortem (P
M) and cooked in bags in water (WC) or on a belt-grill (BG) oven. The
24-h PM WC samples were significantly (P < .05) lower in yield. The WC
samples were lower in moisture than BG samples. Samples deboned 24 h
PM required significantly less force to shear than samples deboned 2 h
PM. Within PM time, WC samples required more force to shear than BG s
amples. Factor analyzed data indicated that two primary categories of
sensory attributes explained about 84% variation in data. Factor I (64
%) included mechanical-geometrical characteristics (hardness, chewines
s, fibrousness, and particle size and shape) and separated samples bas
ed on PM deboning time, Factor II (20%) related to moisture characteri
stics and discriminated samples on the basis of cooking method. Sample
s cooked by the BG method were more uniform in height, cooked faster,
and exhibited a higher yield than WC samples.
