Abstract

This study was carried out to investigate the steaming and wet grinding conditions to save effective compositions and to utilize whole roots of ginseng. The sweetness at the 3 different steaming conditions of non steaming group (A), $95^{\circ}C$/3 hr group (B) and $121^{\circ}C$/15 min group (C) resulted in 7.7, 10.7 and $11.2^{\circ}Brix$, and the browning intensity of 0.37, 1.97 and 1.50, respectively. The contents of crude saponin at the different steam heat treatments were 7.19 (A), 6.99 (B) and 8.83 mg/g (C). When sensory evaluation was conducted, the ginseng products processed at C condition showed the highest scores in the evaluation categories of bitter taste reduction, sweetness and overall acceptance. These results suggest that sensory characteristics of ginseng could be enhanced by the steam heat treatments. When the wet grinding with water addition volume to the steamed ginseng treated at $121^{\circ}C$ for 15 min was also investigated, the smallest particle size resulted from the water addition volume of 300%. The grinding efficiency of ginseng was found to be high at 30 min of grinding time and 3 times of grinding frequency with the mean particle size of $67.66\;{\mu}m$. The content of effective component did not show significant differences by grinding time and grinding frequency. Based on the results, the steam heat treatments ($121^{\circ}C$/15 min) and wet grinding procedures were found to be effective in utilizing whole roots and saving the effective compositions of ginseng.

본 연구에서는 인삼의 유용성분 강화 및 인삼 전근 활용을 위한 증숙 및 습식분쇄 조건을 조사하였다. 그 결과 무처리(A), $95^{\circ}C$/3 hr(B) 및 $121^{\circ}C$/15 min(C)의 증숙조건에 의해 각각의 당도는 7.7, 10.7 및 $11.2^{\circ}Brix$, 갈색도 0.37, 1.97 및 1.50로 증숙구간에서 당도 및 갈색도가 높게 나타났다. 조사포닌 함량은 7.19(A), 6.99(B) 및 8.83 mg/g(C)으로 C 조건에서 가장 높게 나타났다. 관능검사를 실시한 결과 C 조건에서 쓴맛 감소, 단맛 강도 및 전반적 기호도가 가장 높게 나타나 증숙처리 조건에서 관능적인 특성을 향상시킬 수 있었다. 가수량에 따른 습식분쇄 조건을 조사한 결과 가수량 300%에서 입자가 가장 작게 나타났다. 인삼의 습식분쇄조건은 분쇄 30분 및 3회에서 분쇄효율이 높았으며 평균입자크기는 $67.66\;{\mu}m$로 미세화되었다. 분쇄시간 및 횟수에 따른 유효성분 함량은 큰 차이가 없었다. 이상의 결과 증숙처리($121^{\circ}C$/15 min) 및 습식분쇄는 인삼의 전근 활용 및 유효성분 강화에 효과적인 것으로 확인되었다.
