Abstract

Environment-friendly agricultural products are consumed widely, but little is known about consumers' acceptability. The objectives of this study were to 1) determine consumers' acceptability of cucumber when consumed raw, 2) determine differences in appearance liking between environment-friendly and conventionally grown cucumber samples, and 3) analyze the physicochemical properties of cucumber. White dadagi, gasi, non-pesticide mini cucumber, organic gasi, and organic Joseon cucumber samples were evaluated for consumers' acceptability using a nine-point hedonic scale; White dadagi, organic Joseon, and organic gasi cucumber samples showed the highest acceptability scores. However, there were three consumer segmentations differing their degree of cucumber liking and preference. Consumers liked the appearance of organic gasi best. Consumers' preference of cucumbers did not change upon evaluation of the acceptability of the appearance of whole fruit with and without a label indicating an environment-friendly status. Additionally, the physicochemical properties of the cucumbers-including color (skin and flesh), length, circumference, weight, water activity, brix, and texture (hardness and fracturability)-were measured. All measurements showed significant differences among samples, with the exception of water activity and hardness. White dadagi was 3.8 brix, which was the highest among cucumbers, followed by non-pesticide mini cucumber and organic Joseon. White dadagi, organic Joseon, and organic gasi showed greater fracturability than the other cucumber samples.

친환경농산물이 많이 소비되고 있는 반면에 소비자의 기호도에 관한 연구는 부족한 실정이다. 본 연구의 목적은 국내에서 시판되는 오이를 생식으로 섭취할 경우 소비자의 기호도에 차이가 있는지를 알아보고, 친환경오이와 일반오이에 대한 소비자 외관 기호도 차이가 있는지, 그리고 친환경오이와 일반오이의 물리화학적 특성을 연구하고자 하였다. 9점척도법을 이용하여 백다다기오이, 가시오이, 무농약미니오이, 유기농가시오이, 유기농조선오이에 대한 소비자의 기호도를 조사하였고, 전반적인 기호도에서는 백다다기오이, 유기농조선오이, 유기농가시오이를 선호하였다. 그러나 오이에 대한 기호도와 선호도가 다른 소비자의 소그룹이 있었다. 외관 기호도를 평가하였을 때, 친환경농산물 여부에 관계없이 유기농가시오이를 가장 선호하였다. 물리화학적 특성으로 껍질과 과육의 색도, 오이의 길이, 둘레, 무게, 수분활성도, 당도, 조직감(경도, 부서지는 정도)을 측정한 결과, 수분활성도와 경도를 제외한 모든 특성에서 시료간에 유의적인 차이가 있었다(p<0.05). 백다다기오이의 당도는 3.8 brix로 오이 시료 중 가장 높았고, 그 다음으로는 무농약미니오이와 유기농조선오이의 순이었다. 백다다기오이, 유기농조선오이, 유기농가시오이는 부서지는 정도가 다른 시료보다 높았다. 명도는 백다다기오이가 가장 높았으며, 무농약미니오이, 유기농가시오이, 가시오이 사이에는 유의적인 차이가 없었다.
