Abstract
This study analyzed the physicochemical characteristics and sensory properties of makgeolli. Fifteen samples of 4 award winning makgeolli and 11 samples of non-award winning makgeolli in a Korea liquors contest were examined. Physicochemical analysis revealed a significant differences in the alcohol content, reducing sugar concentration, color difference, and volatile compounds between the award winning and non-award winning makgeolli (p<0.05). The award winning makgeolli was related to the high contents of alcohol and reducing sugar, bright color, and low contents of ethyl myristate. A total of 24 terms (appearance 2, odor 10, flavor and taste 8, and texture 4) were expressed in terms of makgeolli. Regarding the sensory property, the sweet, raspberry, pear, and yogurt smell were positively related to the award winning makgeolli. In addition, nuruk, savory smell, and savory flavor were positively related to the non-award winning makgeolli. A study of association between the volatile compounds and odor attribute revealed ethyl lactate to have a positive correlation with the raspberry smell (r=0.840) and pear smell (r=0.723) in the award winning makgeolli (p<0.01). The characteristics of makgeolli preferred by consumers are strongly related to the sweet taste and smell, bright color, and fruit flavor.
