The purpose of this study was to investigate the quality characteristics of Gamgyul-Injeulmi containing different ratios of Citrus mandarin powder(0, 3, 6, 9 and 12%). The moisture content of the control group was 45.37%. As the ratio of Citrus mandarin powder increased, moisture content decreased. The water holding capacity of glutinous rice flour with Citrus mandarin powder decreased gradually in proportion to the amount of Citrus mandarin powder added. An analysis of Hunter's color values for Gamgyul-Injeulmi indicate that the addition of Citrus mandarin powder leads to lower L value and higher a and b value compared to the control. Textural analysis of Gamgyul-Injeulmi showed that the hardness, cohesiveness, gumminess and chewiness increased as Citrus mandarin powder was added, whereas adhesiveness and springiness decreased. According to the sensory evaluation of Gamgyul-Injeulmi, as the ratio of Citrus mandarin powder was increased, the flavor, sweetness and hardness all increased. Gamgyul-Injeulmi with 6% Citrus mandarin powder was rated as the best in terms of color and for overall preference in the sensory evaluation.

The purpose of this study was to investigate the quality characteristics of Gamgyul-Injeulmi with different ratios of Citrus mandarin powder(0, 3, 6, 9, 12%) during storage. The moisture contents of the Gamgyul-Injeulmi decreased during storage but the moisture content of control(containing 0% Citrus mandarin powder) was almost constant. According to amylograms, gelatinization temperatures were lower in the samples containing Citrus mandarin powder compared to the control. More additions of Citrus mandarin powder caused lower viscosity and breakdown values but higher setback values. The pH of all samples decreased during storage but as more Citrus mandarin powder was added the changes in pH were less. The titratable acidity of all samples increased during storage and more additions of Citrus mandarin powder resulted in higher titratable acidity. For the Hunter's color values during storage, L and a values decreased but b values was increased except for the control. Textural analyses of the Gamgyul-Injeulmi showed that hardness, gumminess and chewiness increased, whereas adhesiveness, cohesiveness and springiness decreased during storage.
