Abstract

This study was carried out to investigate the quality characteristics of ginseng Jung Kwa obtained by treatments with different sugars. Ginseng Jung Kwa was made with four different sugars (sucrose, glucose, honey and fructose). Chemical characteristic was measured by ginsenosides content and rheological characteristics were measured by rheometer and color meter. Total ginsenoside and Rf contents on Ginseng Jung Kwa by sucrose were highest at 10.0, and 7.82 mg/g, respectively. On ginseng Jung Kwa by fructose, total ginsenoside content was the lowest, and hardness and adhesiveness were the highest, and by honey, stiffness, cohesiveness, gumminess, chewiness, and springiness were the highest, and fracture force did not appear as a significant difference by treatment of different sugars. Coefficient of variance on ginseng Jung Kwa by honey was the highest. On ginseng Jung Kwa by sucrose, color (lightness, redness and yellowness) all were the highest. Browning on Jung Kwa by fructose was the greatest. Sensory evaluation preference analysis (color, taste, texture, flavor and overall acceptability) on ginseng Jung Kwa were determined by 50 panelists (30~50's age) using 5-point scale. On ginseng Jung Kwa by honey, texture and overall acceptability were the best. Ginseng Jung Kwa by fructose was very sticking and adhering, so preference by sensory evaluation was inferior to others.

인삼정과 제조 시 물성학적 품질을 향상하는데 기초자료를 얻고자 sucrose, glucose, honey 및 fructose 등 4종의 당을 각각 첨가하여 제조한 인삼정과에 대하여 진세노사이드 함량, 물성 및 색도를 기계적인 측정치와 관능요원들의 평가치에 의하여 특성을 조사하였다. 조성 진세노사이드 중에서 Rf가 당 종류종별에 따라 각기 함량에 큰 차이를 보여 sucrose로 제조한 인삼정과에서 가장 함량이 높았으며 glucose>honey>fructose의 순으로 높은 결과를 보여주었고 검출된 7종의 진세노사이드의 총 함량은 sucrose로 제조한 인삼정과가 10.0 mg/g으로 가장 높은 함량을 보였으며 glucose>honey>fructose의 순으로 높아 fructose로 제조한 인삼정과가 가장 낮은 함량을 보여주었다. Hardness와 adhesiveness가 가장 높은 것은 fructose를 이용하여 제조한 정과이었고 stiffness, cohesiveness, gumminess, chewiness 및 springiness는 honey를 이용하여 제조한 정과이었으며 fracture force는 당 종류에 따라 차이가 크게 나지 않았다. 당 종류별 정과제품의 편차는 honey가 가장 높게 나타나 제품의 균일성이 떨어지는 현상을 보였다. 정과의 색도 중 밝기, 적색도 및 황색도 모두 sucrose에서 가장 높았으며 적색도가 가장 낮은 것은 glucose, 황색도는 fructose에서 가장 낮게 나타났다. 정과제조 시 당의 종류 중 fructose 함량이 높을수록 갈색화가 크게 일어남을 볼 수 있었다. 관능평가에서는 honey를 이용한 인삼정과가 조직도와 전체적인 기호도면에서 가장 좋았으며 fructose를 이용한 정과는 조직도면에서 기호도가 가장 낮았다.
