Abstract

This study examined the physiochemical and organoleptic properties of the yanggaeng fabricated with different contents of ginger powder. The moisture contents ranged between 39.85% and 47.92%. The yanggaeng made with 0.5 g of ginger powder showed the lowest moisture content of 37.04%, whereas the yanggaeng made with 1.5 g of ginger powder showed the highest moisture content of 47.92%. As for the L value, which indicates lightuess, the yanggaeng made with 1.5 g of ginger powder showed a L value of 13.92, whereas the yanggaeng made with 0.5 g showed the lowest L value of 12.35, (p<0.05). The values for redness (a value) ranged between 4.69 and 5.58, and there was no significant difference as the content of ginger powder increased. The value for yellowness, (b value) ranged between 3.19 and 2.33, and showed a significant decreasing trend as the ginger powder content increased (p<0.05). The sugar concentrations were 53.82~46.56, and decreased as the ginger content increased. The pH ranged between 6.42~6.52, and showed significant differences. As the ginger content increased, changes in hardness, adhesiveness, gumminess, and chewiness, were all significant (p<0.05). Characteristics of cohesiveness and springiness, showed no significant differences. Although there were no significant differences in color, flavor, chewiness, and hardness, there was a decreasing flavor preference as the content of ginger powder increased. There were significant differences in sweetness, moistness, and overall-preference (p<0.05). For overall-preference, the yanggaeng with 1.0 g of added ginger powder showed a high preference level. The study results implied that ginger powder may be used in fabricating yanggaeng. and a 0.5% content of added ginger powder will improve the preference level.
