This study was performed to analyze the retarded degree of Garaetteok retrogradation added with different ratios 0-15% (w/w) of apple pomace dietary fiber powder (DFP). SEM (${ imes}$500) showed that air cell size on the Garaetteok surface increased as DFP content increased, whereas control had a compact structure without air cells. The degrees of Garaetteok retrogradation after 3 days at 4 and 25$^{circ}C$ by ${alpha}$-amylase iodine method were 57.44 and 41.55% for control, respectively. On the other hand, those of 15% DFP Garaetteok were 28.38 and 15.05%, respectively. Enthalpy changes (${Delta}$E) by DSC of control, 10 and 20% DFP Garaetteok after 3 days of storage at 4$^{circ}C$ were 4.41, 4.17, and 3.80 J/g, respectively, whereas those at 25$^{circ}C$ were 2.14, 1.04, and 0.72 J/g. Hardness of 15% DFP Garaetteok was around 48% compared to that of control after 3 days of storage at 25$^{circ}C$. Increasing DFP content from 0 to 15% decreased L color value from 86.2 to 55.1, whereas a and b values increased from -1.9 to 8.9 and from 5.3 to 20.8, respectively. In a sensory intensity test, hardnesses of 15% DEP Garaetteok were significantly different at 1 and 0.1% compared to those of control after production and followed by storage for 3 days at 4$^{circ}C$, respectively.
