| Abstract |
| A liquor market is one of the consumers for the water industry. In this study, using groundwater as raw water, waters of various hardness were produced by a nano-filtration process, and a sensory test analysis was performed to determine the range of hardness that best meet the sensory expectations of domestic consumers. According to Korea standard, water samples were investigated using the hedonic scale method for preferences for odor, swallow and taste. ANOVA was performed using the XLSTAT program and Tukey HSD test was performed to determine whether differences were significant. In the sensory test, four criteria were evaluated in the form of a blind test for water at four hardness levels, 0, 10, 35, and 50 mg/L, by 31 panels. It was found that odor did not differ with hardness, whereas there was relatively high preference at the 95% confidence level for water with a hardness of 10 mg/L in categories of swallowing and taste. Through the results of this study, it will be possible to prepare the basis for the development of differentiated alcoholic beverage products that meet consumer satisfaction. |
