We aimed to investigate the effect of citrus peel powder (CP) on the physicochemical, antioxidant, and sensory properties of Yanggaeng when treated with various levels (CON (0%), CP2 (2%), CP4 (4%), and CP6 (6%)) of CP. With an increase in CP content, Yanggaeng displayed a significantly elevated free radical scavenging rate, as indicated by increased 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2 '-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) diammonium salt (ABTS) free radical scavenging rates, as well as ferric reducing antioxidant power (FRAP). Furthermore, the addition of CP significantly reduced the pH and increased Brix values compared to the control (CON). CP treatment also exhibited a dose-dependent effect on colorimetric properties, resulting in decreased L* and increased a* and b* values. Moreover, CP addition changed the textural characteristics of Yanggaeng, escalating gumminess, hardness, and chewiness, while reducing adhesiveness. In terms of consumer preferences, Yanggaeng containing 4% CP (CP4) closely resembled CON in terms of attributes such as flavor, taste, sweetness, chewiness, purchase intent, and overall acceptance. However, Yanggaeng containing 2% (CP2) or 6% (CP6) CP led to a decreased overall preference for Yanggaeng. In conclusion, based on our findings, CP4 appears to be the most suitable choice for enhancing both the physicochemical and sensory properties of Yanggaeng. Furthermore, adding CP to Yanggaeng serves as a foundation for novel food production incorporating CP.
