This study investigated the quality characteristics of Yanggaeng added with lentil bean sediment. Yanggaeng was prepared by addition of 0, 25, 50, and 75% (w/w) lentil bean sediment to white bean basic formulation. For the proximate composition measurement, lentil bean sediment consisted of 15.63% moisture, 17.31% crude protein, 0.92% crude ash, and 0.31% crude fat. The sediment yield of lentil beans was 54.25%. The moisture content of Yanggaeng significantly increased with increasing lentil bean sediment content. The total soluble solid content (°Brix) of Yanggaeng significantly decreased with increasing lentil bean sediment content, whereas the pH was not significantly different between the control and experimental groups. The lightness of Yanggaeng significantly decreased with increasing lentil bean sediment content, whereas redness and yellowness significantly increased with increasing lentil bean sediment content. The springiness, gumminess, and chewiness of Yanggaeng decreased with increasing lentil bean sediment content, whereas hardness and cohesiveness was not significantly different between the control and experimental groups. The total phenolic content and 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity significantly increased with increasing lentil bean sediment content. Yanggaeng containing 25% lentil bean sediment had acceptable sensory properties, such as taste, texture, and overall preferences. Thus, our results suggest that Yanggaeng containing 25% lentil bean sediment could improve the sensory properties and antioxidant activities of Yanggaeng.
