NaCl 농도가 인삼의 ginsenoside 함량과 pH 및 색의 변화에 미치는 영향 = Effect on the change of ginsenosides, pH and color by NaCl concentration

국문 초록 (Abstract)

인삼을 조미제품의 첨가성분으로 이용할 때 그 NaCl 농도에서 인삼성분의 안정성을 규명하기 위하여, 미삼과 홍삼정을 NaCl 농도별로 처리하여 pH, 색상 및 ginsenosides 함량을 조사한 결과, 미삼의 경우 NaCl 농도가 증가 할수록 pH는 높아졌으나 홍삼정 시험구에서는 유의적인 변화가 없었다. 색상은 NaCl 농도가 증가 될수록 감소하였다. n-BuOH extract 수율은 5% NaCl 농도에서 감소하였고 그 이상의 농도에서는 증가하는 경향을 나타내었으며, 증감 범위는 홍삼정이 컸다. Ginsenosides 함량은 diol계 saponin인 ginsenoside-Re, $-Rb_1$, $-Rb_2$, -Rc, -Rd 및 triol계 saponin인 ginsenoside-Re 모두 5% NaCl 농도에서 감소하였고 그 이상의 농도에서 증가하는 경향이었으며, 특히 ginsenoside-Re가 가장 민감한 증감의 변화를 보였다.

In order to determine the stability of ginseng components in this salt concentration when used to ginseng as additive ingredient of sauces or seasonings, we study on the content and charactristic of ginsenosides and changes in pH and color, ginseng tail and ginseng extract were treated with various concentration of NaCl solution. In this experiment, extract of ginseng tail were increased in pH as NaCl concentration were increased, but ginseng extract have not changed evidently. The both solution were decreased in color as the salt concentration were increased. Yield of n-butanol extract was decreased in 5% NaCl concentration, while it was increased in the above concentration, and ginseng extract was changed higher than ginseng tail. Ginsenosides content were increased in 5% NaCl concentration, both $ginsenosied-Rb_1$, $-Rb_2$, -Rc, -Rd of diol line and ginsenoside-Re of triol line and increased in above NaCl concentration. Especially ginsenoside-Re showed to sensitive response to the changes of the salt concentration.
