This study was conducted to investigate the physicochemical quality characteristics of pork patty added with four different amount (T0:0%, T1:0.3%, T2:0.7%, T3:1.0%) of tangerine (Citrus unshiu) peel. There was no significant difference in chemical composition, cooking yield, water holding capacity, moisture retention, fat retention, hardness, springiness, cohesiveness, gumminess, chewiness, VBN content, L-value. In taste, texture, juiciness and palatability, the addition of 0.3%~1.0% tangerine peel in pork patty showed no significant difference on sensory properties compared to the pork patty without tangerine peel. Total polyphenol content was highest in T3, and DPPH radical scavenging activity was highest in T2 and T3 (p<0.001). The TBARS contents decreased as tangerine peel become added (p<0.001). The pH was highest in T0, and was lowest in T3 (p<0.001). The external a-value of T2 and T3 were significantly higher than that of T0 (p<0.01). The external and internal b-value of T2 and T3 were higher than those of T0 (p<0.01). Flavor of T2 and T3 were higher than those of T0 and T1 (p<0.01). In conclusion, the results of this study indicate that an addition of tangerine peel could be utilized as an ingredient in pork patty in promotion of function of tangerine by-products.
