This study investigated the proximate composition, sweetness, color, texture, and sensory properties of baked Gangjung prepared using different coating syrups (maltose syrup, oligosaccharide, rice syrup, and maltitol syrup). The crude protein content was 3.22~3.28% in baked Gangjung prepared with maltose syrup, oligosaccharide, or rice syrup, while that prepared using maltitol syrup had 2.61%. Crude ash was the highest when rice syrup was used (1.08%), and the lowest when maltose syrup or oligosaccharide was used (0.64% and 0.68%, respectively). The sweetness of the baked Gangjung was the highest in the rice syrup group, at 70.07 °Brix, and lowest in the maltose syrup group, at 33.5 °Brix (p<0.05). The hardness of the Gangjung prepared with the different coating syrups was the highest for the grain syrup (1.42), followed by the oligosaccharide group at 0.96, maltose syrup (0.40), and maltitol syrup (0.35) (p<0.05). The number of peaks and the indirect measure of crispness also showed the highest values for the rice syrup group (p<0.05), but there was no significant difference among the values in the other groups. Lightness was in the range of 63.26~73.04 depending on the coating syrup, decreasing from the oligosaccharide to the maltitol, rice syrup, and then to the maltose syrup group (p<0.05). The a-value was the highest for the maltose and rice syrup groups at 10.69 and 10.38, respectively (p<0.05), and the b-value showed the same trend. Baked Gangjung showed the highest scores for color, flavor, and overall preference when prepared using maltitol syrup.
