Purpose: This study aimed to investigate the effect of grape skin on the physicochemical properties and sensory score of ground pork meat.
Methods: Four types of ground pork were evaluated: T0 without grape skin, T1 with 0.3% grape skin, T2 with 0.7% grape skin, and T3 with 1.0% grape skin.
Results: There was no significant group wise difference in VBN content, L-value, b-value, chemical composition of raw and cooked meat, cooking yield, water holding capacity, moisture retention, fat retention, hardness, springiness, cohesiveness, gumminess, chewiness, taste, texture, juiciness, or palatability. Total polyphenol content was highest in T3, and DPPH radical scavenging activity was highest in T2 and T3 (p<0.001). The pH was highest in T0, and was lowest in T3 (p<0.001). The a-value of T2 and T3 were significantly higher than that of T0 (p<0.05). Flavor was highest in T2 among samples (p<0.01).
Conclusion: The study results suggest that grape skin may be a useful ingredient in ground pork meat in terms of antioxidant potential, color and flavor.
