|
The study investigated the physicochemical and sensory characteristics of Tarakjuk added with various concentrations of Stachys sieboldii Miq root. Tarakjuk prepared by addition of 0, 10, 20, and 30% powder to rice flour basic formulation. The spreadability and moisture content of Tarakjuk increased with addition of Stachys sieboldii Miq root powder, whereas viscosity decreased with addition of Stachys sieboldii Miq root powder. The pH of Tarakjuk decreased with addition of Stachys sieboldii Miq root powder, whereas acidity increased. The lightness of Tarakjuk decreased with addition of Stachys sieboldii Miq root powder, whereas redness and yellowness increased with addition of Stachys sieboldii Miq root powder. 1,1-Diphenyl-2-picrylhydrazyl radical scavenging activities of Tarakjuk significantly increased as Stachys sieboldii Miq root powder content increased (P<0.05). The results of the sensory evaluation showed that the flavor and taste of Tarakjuk were not significantly different among the samples. Appearance, aftertaste, texture, and overall acceptability showed the highest scores for Tarakjuk containing 10% Stachys sieboldii Miq root powder. Based on the results of this study, Tarakjuk added with 10% Stachys sieboldii Miq root was determined to be optimum for its good characteristics and overall acceptability.
