Abstract

The sensory characteristics of nine rice-based distilled soju were determined using check-all-that-apply (CATA) profiling. A total of 53 consumers evaluated the soju for two appearance attributes, nine aroma attributes, nine flavor/taste attributes, four mouth-feel related sensory attributes, and overall desirability. The total sum of CATA terms indicated that 14 characteristics showed frequency differences of over 10 and that there were significant differences among nine samples for eleven sensory attributes as determined using Cochran's q test (p<0.05). Based on correspondence analysis of CATA data, the samples were primarily separated by the first dimension, which accounted for 89% of the total variance among samples. The "brown color," "fruit taste," and "grain aroma" characteristics had higher frequencies than those for the "white color," "acetone aroma," and 'alcohol taste" characteristics. Overall, there was a higher preference for oak-aged samples than for samples aged in other containers. "sweet aroma', 'fruit aroma," and "sweet taste" seemed to positively affect consumer preferences, while "bitter taste," "alcohol taste," and "acetone aroma" appeared to negatively affect consumer preferences as determined by principal coordinate analysis.

CATA 방법을 이용하여 저장용기를 달리하여 숙성한 증류식 소주와 시판 제품의 감각 특성을 파악하고 소비자 기호도를 조사하였다. CATA 용어의 총 합을 분석한 결과 총 21가지 특성 중 14가지 특성에서 빈도수 차이가 10 이상으로 나타났으며, 11가지 특성에서 시료간의 유의적인 차이가 존재한 것으로 나타났다. 대응 분석 결과 F1상에서 오크 숙성 시료가 양의 방향으로 분포하였으며, 나머지 시료가 음의 방향으로 분포하여 오크 숙성에 의한 증류식 소주의 감각특성의 차이를 확인하였다. 전반적으로 오크숙성과 관련 특성이 높게 나타난 JRJ, 6RO, 18RO가 기호도 평가에서 전반적으로 높은 평가를 나타내었다. 기호도와 감각 묘사용어 빈도수 합의 관계를 살펴보면, 단향, 과일맛, 단맛의 경우 기호도에 긍정적인 영향을 미치며, 알코올향, 아세톤향, 쓴맛은 부정적인 영향을 미치는 것을 알 수 있다. 스테인레스 스틸과 옹기 같은 숙성용기와 숙성기간에 따른 감각특성의 차이는 CATA 평가를 통해서는 뚜렷한 차이를 확인하지 못 하였다. 향후 CATA 조사 인원 확대 및 다양한 감각평가 방법의 적용을 통해 이러한 차이도 파악이 가능하리라 여겨진다.
