Effect of ginger extract on Korean black goat biceps femoris as a tenderizer

This study investigated the tenderization and quality characteristics of Korean black goat biceps femoris treated with ginger powder extracts (0 %, 3 %, 5 %, and 7 %). The proximate composition, pH, color, shear force, water-holding capacity, sarcomere length, fiber cross-sectional area, and sensory properties were determined and analyzed according to the concentration of the ginger powder extract. The shear force decreased significantly with increasing concentrations of ginger powder extract (P < 0.05), whereas the water-holding capacity increased (P < 0.05). The sarcomere length of black goat biceps femoris increased with increasing concentrations of ginger powder extract (P < 0.05), whereas the fiber cross-sectional area decreased (P < 0.05). Sensory evaluation of black goat biceps femoris showed that goatiness decreased with increasing concentrations of ginger powder extract (P < 0.05), and the chewiness and overall acceptability were significantly higher (P < 0.05). Therefore, 7 % was the optimal concentration for softening black goat biceps femoris with ginger powder extract. In conclusion, it was confirmed that Korean black goat biceps femoris marinated in 7 % ginger extract was softened, and it is judged that this will have a positive effect on the texture of commercial Korean black goat meat.
