This study was carried out to investigate the effect of paprika (Capsicum annuum L.) to the quality of makgeolli fermented by nuruk at 23 o C for 6 days. The changes in pH, total acidity, ethanol content, color, antioxidant activity, total polyphenol content and sensory evaluation were determined. Our results showed that the pH decreased from 5.6-6.1 to 4.2-4.3 and the total acidity increased from 0.03-0.05% to 0.27-0.32% after 6 days in makgeolli fermentation. The ethanol content was 12.0-15.1% after the fermentation. There was no significant difference on antioxidant activity and total polyphenol content depending on the addition of paprika. The results of sensory evaluation revealed that the color, flavor, sweetness, bitterness, and overall acceptance of makgeolli with 10% paprika were markedly higher than those of the control and other samples. Taken together, our results indicate that makgeolli with 10% paprika had no significant effect on the physiological characteristics, however it showed the best palatability.
