The effects of Crataegus pinnatifida bunge powder(CP) on dough characteristics and bread quality were evaluated. Breads were prepared with the addition of 0, 3, 6 and 9% CP to the basic formulation. The pH of dough added with CP ranged from 5.26 to 5.34, while control dough had a pH of 5.80. The loaf volume index of bread prepared with $3{\sim}9%$ CP decreased by $5.4{\sim}16.9%$ Hardness increased with the addition of CP, but the cohesiveness and springiness decreased with the addition of 3 and 6% CP and increased with the addition of 9% CP. Color L value of the bread crust and crumb decreased with CP and color a and b values of the bread crumb increased with CP. The sensory quality of bread with 6 or 9% Crataegus pinnatifida bunge powder, as estimated by shape, flavor and overall quality, was worse than that of control bread, while bread with 3% Crataegus pinnatifida bungs powder had the best quality.

This study was performed to determine the effects of drying methods (HD, hot air drying; FD, freeze-drying) on the antioxidant and physiological abilities of Haw (Crataegus pinnatifida Bunge). Powder color values of dried Haw, L and b, were higher for HD, while the chroma values were higher for FD. The total polyphenol, and flavonoid contents of HD Haw and FD Haw were found to be $9.29{\pm}0.50mg\;GAE/mL$ and $15.48{\pm}0.38mg\;GAE/mL$, and $9.41{\pm}0.26mg\;RHE/mL$ and $26.46{\pm}0.34mg\;RHE/mL$, respectively. DPPH radical scavenging abilities at 100 mg/mL concentration were higher for FD (64.90%) than HD (28.66%), as were the reducing power, ABTS radical scavenging ability, and nitrite scavenging ability. However, the HMG-COA reductase of HD (74.67%) was higher than that of FD (72.10%). The ${\alpha}-glucosidase$ inhibitory abilities of HD and FD at a concentration of 0.1 mg/mL were 24.69% and 97.38%, respectively. These results indicate that Haw is a potential functional material and that freeze-drying Haw is better than hot air drying.
