Quality Properties of Dry-Aged Beef (Hanwoo Cattle) Crust on Pork Patties.

This study evaluated the effects of crust derived from dry-aged beef (Hanwoo cattle) on the quality of pork patties. Pork patty samples were prepared with different amounts of crust (0-control, 1, 2, and 3%). The protein, fat, and ash contents in the crust samples were significantly higher than those in the control sample ( p < 0.05). The CIE b * value of uncooked pork patties with crust added was significantly lower than that of the control patties ( p < 0.05). The pH and CIE L* values of uncooked patty batter samples decreased with increasing concentrations of crust ( p < 0.05). However, the viscosity increased proportionally with an increase in crust ( p < 0.05). Samples containing 3% crust showed significantly higher uncooked and cooked CIE a*, water-holding capacity, cooking yield, and shear force than the control sample ( p < 0.05). Moreover, samples containing 2% and 3% crust showed significantly lower diameter and thickness reductions than those of the control sample ( p < 0.05). The sensory evaluation conferred by the crust was significantly higher than that of the control sample ( p < 0.05). Overall, our results suggest that pork patties supplemented with 3% crust have improved properties.
