The optimum extraction of phenolic compounds from whole Rosa multiflora Thunberg fruits was accomplished using 70% ethanol, which produced extracts that generated a zone of inhibition around Helicobacter pylori of 13 mm when 200 ㎍/mL phenolic compounds were applied. In this study, the quality of white bread baked from dough containing added Rosa multiflora Thunberg extracts was investigated. No deterioration of product quality factors including hydration of wheat flour, formation of dough and internal visual characteristics of dough was observed. However, white bread containing Rosa multiflora Thunberg extracts had a wet texture because of the high moisture level, as well as a high number of irregular bubble holes when compared to the control. Nevertheless, there were no remarkable differences between the sample and the control.
