증숙 횟수에 따른 고려인삼의 이화학적 특성 변화 = Changes on Physicochemical Properties of Panax ginseng C. A. Meyer during Repeated Steaming Process

국문 초록 (Abstract)

국내 인삼은 대부분이 수삼 또는 백삼, 홍삼 등의 1차 가공제품으로 가공되어 유통되고 있으나 최근 들어서는 인삼의 효능 및 성분 강화를 위하여 발효, 가압처리, 고온처리 등 다양한 방법들이 시도되고 있다. 본 연구에서는 국내산 5년근 수삼을 이용하여 9회의 증숙과 열풍건조를 반복 수행하면서 중량, 색도, 갈변도, 수분, 당류, 산성다당체, 총 페놀화합물, 조사포닌 및 주요 진세노사이드의 함량 변화를 살펴보았다. 수분의 경우 초기 73.4%에서 3회 처리 시 21.2%까지 감소하고 이후 9회 처리 시 13.7%까지 감소하였다. 최종 중량수율은 약 21.0%, 건물기준 최종수율은 79.0%이었다. 색의 경우 밝기를 나타내는 L값은 감소하고 적색도를 나타내는 a값은 증가하는 경향을 나타내었으며 갈변도는 3회 증숙처리 이후부터 급격히 증가하는 경향을 나타내었다. 가용성 총당은 초기 55.4%에서 9회 처리 시 38.6%로 감소한 반면 산성다당체 함량은 4.4%에서 6.8온까지 증가하였다. 총페놀함량은 초기 0.4%에서 3회 처리 시 0.9%로 9회 처리 시에는 3.6%까지 증가하였다. 물포화부탄올 추출물 즉 조사포닌 함량은 처리횟수가 증가할수록 서서히 증가하는 추세를 나타내었다. 주요 진세노사이드 함량 변화를 살펴본 결과에서는 ginseno-side $Rb_1$, $Rb_2$, $Rg_1$, Re 등의 함량은 감소하고 $Rg_2$, $Rh_1$, $Rg_3$ 등의 홍삼 특이성분 함량은 5번 증숙처리 이후부터 크게 증가하였다.

다국어 초록 (Multilingual Abstract)

Changes on physicochemical properties of fresh Korean ginseng during repeated 9 times steaming processes, steaming $90{\sim}95^{\circ}C$ for $1{\sim}3\;hr$ followed by hot air-drying at $50^{\circ}C$ for $36{\sim}48\;hr$, were investigated. The water contents decreased from 73.4% of fresh ginseng to 13.7% finally. The final yields in bases of total weights and dry matter were 21.0% and 79.0%, respectively. As the times of steaming processes increased, lightness (L value) decreased and redness (a value) increased in color of ginseng powder. Browning index also rapidly increased after 3 times of steaming process in particular. Total water soluble sugar contents decreased from 55.4% in fresh to 38.6% in final processed ginseng, but acidic polysaccharide contents increased by about 50% with increasing times of steaming process. Total phenolic compound contents significantly increased with repeated steaming processes especially after 5 times of steaming processes and crude saponin contents also increased in some degree. In the case of major ginsenosides, the contents of $Rb_1$, $Rb_2$, $Rg_1$, Re (representative ginsenosides in fresh ginseng) decreased, but those of $Rg_2$, $Rh_1$, $Rg_3$ (unique ginsenosides in red ginseng) increased after especially 5 times of steaming processes.
