Abstract

Jungkwa is traditional food in Korea and difficult to prepare. This study proposes to use a rice cooker to simplify the process of preparing ginseng jungkwa. The following is the summary of the study. This study examined low calorie sweeteners (xylitol, oligosaccharide, stevioside, erythritol) instead of sugar for ginseng jungkwa to satisfy customers' health needs. After adding sugar, xylitol, oligosaccharide, stevioside, and erythritol to ginseng jungkwa, moisture and sugar content were measured. Based on the results, the ginseng jungkwa made with xylitol had a low moisture content, but it had the highest sugar content. The ginseng jungkwa with xylitol had average sweetness equal to that of sugar. In addition, L-values were highest with stevioside whereas the b-values and a-values were highest with sugar. Hardness and springiness were highest in the ginseng jungkwa added with sugar while adhesiveness was highest in the ginseng jungkwa added with oligosaccharide. In a sensory evaluation, the appearance, flavor, taste, texture, and overall preference were highest for the oligosaccharide added ginseng jungkwa. In the end, the best low calorie sweetener for rice cooker prepared ginseng jungkwa proved to be oligosaccharide.

본 연구는 수삼정과를 저열량 감미료인 자일리톨, 올리고당, 스테비오시드, 에리스리톨을 이용하여 전기밥솥으로 205분 제조하여 품질 특성을 비교하였다. 수삼정과의 수분 함량은 시료 간에 유의적인 차이를 나타내었고, 스테비오시드는 다른 시료들에 비해 수분 함량이 현저하게 높았다. 당도는 시료 간에 유의적인 차이를 보였다. 설탕으로 전기밥솥에 제조한 수삼정과의 명도와 적색도는 유의적으로 비슷한 경향을 보였으며, 자일리톨로 제조한 수삼정과의 황색도가 유의적으로 가장 낮았다. 수삼에 설탕을 넣고 제조한 대조군의 경도는 설탕으로 제조한 수삼정과가 유의적으로 가장 컷으며, 부착성은 시료 간에 유의적인 차이를 보였으나, 경도에 따른 뚜렷한 경향을 나타내지는 않았다. 탄력성은 설탕으로 제조한 것이 가장 컸고, 씹힘성은 시료 간에 유의적인 차이를 보였다. 검성은 유의적인 차이를 보이지는 않았으며, 응집성은 자일리톨과 올리고당으로 제조한 수삼정과의 응집성이 유의적으로 가장 컸다. 관능적인 특성을 검토해본 결과, 정과의 외관, 향, 맛, 종합적인 기호도에서 선호한 올리고당으로 제조한 수삼정과를 다른 대체 감미료로 만든 시료에 비해 높은 점수를 얻었으며, 정과의 윤기, 갈색의 정도, 인삼의 향, 맛도 선호하였다. 따라서 설탕을 대신하여 올리고당을 사용하여 정과를 제조하면 현대인들의 건강에 대한 염려에도 부합하는 칼로리가 낮은 정과의 제조도 가능함을 알 수 있었다.
