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.
