Abstract

Making jungkwa, a traditional Korean snack, is difficult and complicated. In this study, a rice cooker was used to simplify the process of making jungkwa made with ginseng. Comparing ginseng jungkwa cooked in a rice cooker with the control group cooked in a traditional way, their chewiness, browness, glossy and overall preference were similar when cooked for 160 minutes, 175 minutes, 190 minutes, 205 minutes, and 220 minutes. The moisture content of ginseng jungkwa cooked in a rice cooker decreased, while its sugar content increased with increased cooking time. Also, the ginseng jungkwa had lower lightness and higher redness and yellowness as its cooking time got longer. The ginseng jungkwa cooked for 205 minutes was most similar to the one cooked in a traditional way. In the measurement of texture, the ginseng jungkwa had higher hardness with increased cooking time, and, when cooked for 205 minutes, it was most similar to the one cooked in a traditional way in chewiness. The sensory evaluation showed that the one cooked for 205 minutes was most preferred in appearance, smell, taste, texture and overall preference. Based on these results, this study revealed that using a rice cooker can be substituted for the traditional way of making jungkwa.

본 연구는 정과를 전통적인 방법보다 간편하게 제조하고자 전기밥솥을 이용하여 수삼 정과를 제조하고자 하였다. 전기밥솥에 수삼 정과를 제조할 경우 졸임 시간이 길어질수록 수분 함량은 줄고 당도는 높아졌다. 또한 졸임 시간이 길어질수록 명도는 낮아지고 적색도와 황색도는 유의적으로 높아졌고 205분 졸인 정과가 전통적인 방법으로 제조한 정과와 색이 가장 비슷하였다. 텍스처 측정 결과 졸임 시간이 길수록 경도는 높아 졌고, 경도와 씹힘성은 205분 졸인 정과가 전통적인 방법으로 제조한 정과와 가장 비슷한 수치를 보였다. 관능검사 결과 정과의 외관, 향, 맛, 텍스처, 종합적인 기호도에서 전기밥솥에 205분 졸인 것이 가장 선호 되었으며, 전통적인 방법을 대신하여 전기밥솥에 정과를 제조함이 가능함을 알 수 있었다.
