The purpose of this study is to develop value-added functional gruel by adding fresh burdock & burdock powder. For burdock, we put fresh burdock(1.0, 2.0, 3.0, 4.0%) and burdock powder(0.3, 0.6, 0.9, 1.2%) into burdock gruel and get results from mechanical tests and sensory tests. Moisture content of fresh burdock gruel increased with more addition of fresh burdock, while burdock powder gruel had less moisture content as the addition of burdock powder increased. Lightness and pH decreased in both groups as more amount of burdock was added. From the result of an attribute difference test, 4% fresh burdock gruel showed the strongest burdock flavor and astringent taste. Among the burdock powder groups, the gruel added with 1.2% burdock powder scored the highest point in color intensity, graininess, savory taste, astringent taste, thickness and aftertaste. For overall acceptability, the gruel added with 3% fresh burdock scored the highest point and the gruel added with 0.6% burdock powder was the highest among the burdock powder groups. Based on the results of this study, the gruel added with 0.6% burdock powder and the gruel added with 3% fresh burdock were the optimum for their good characteristics and overall acceptability when produced.
