홍삼추출물(RGE)의 쓴맛을 개선하기 위해서 증숙시 초산 처리 후 α-, β-, γ-CD을 이용 해서 RGE의 포접화합물을 제조하여, 전자혀 분석을 통해서 RGE-γ-CD에 의한 쓴맛 개선효과가 가장 큰 것으로 확인하였다. 인삼의 열처리 공정에 있어 초산 처리는 Rg3 및 비극성 진세노사이드 성분 함량 을 증가시킴을 알 수 있었다. 전자혀를 이용하여 α, β, γ- CD 첨가량에 따른 쓴맛, 신맛, 짠맛, 우아 미맛 및 단맛을 분석하였다. 그 결과 RGE 대비 10%의 γ-CD를 첨가하여 포접한 REG가 다른 처리구 에 비해 쓴맛이 월등히 낮은 감응도를 나타내었다.

The aim of the present study was to determine the effect of dietary cultured wild ginseng root (CWGR) supplementation on goat milk composition and ginsenoside profiles. Sixteen Saanen dairy goats were allocated to two balanced groups based on lactation period, body weight (38.6 ± 3.2 kg), and dairy milk yield (2.85 ± 1.2 kg), and were kept in separate pens. Goats were fed a total mixed ration (TMR) feed (2.3 kg/d, dry matter basis) and 1.5 g of CWGR powder was supplemented in the experimental diet. The total feeding period was 3 weeks, and milk and blood samples were collected on the last three days of the experimental period. There was no effect of CWGR on daily milk yield and milk composition (fat, protein, lactose, and solid-not-fat). However, the CWGR-treatment group had significantly higher plasma IgG and protein contents than the control group (P < 0.05). Significant amounts of ginsenosides were observed in the milk of the CWGR-treatment group, whereas ginsenosides were not detected in the milk of the control group. In conclusion, dietary CWGR was a useful regimen to produce functional goat milk enriched in ginsenosides.

This study was conducted to compare the contents of ginsenoside according the water extract conditions of red ginseng. In method A, red ginseng extract was prepared at 75℃ for 18 hours by 1 time extraction, and method B, the preparation was done at 85℃ for 18 hours by 1 time extraction. In method C, the primary extract prepared at 75℃ for 9 hours was blended with the secondary extract prepared by re-extracting the red ginseng residue obtained after the primary extraction, at 85℃ for 9 hours. Method D was the same procedure as method C but the extraction temperature for the primary extraction was 85℃ and that for the secondary extraction was 95℃. The contents of total and Rb1, Rg1 and Rg3 ginsenoside were highest in Method C. The content of prosapogenin (ginsenoside Rg2, Rg3, Rb1 and Rb2) was highest in Method B. There was no consistent tendency in Brix, pH, Hue value and absorbance among extraction methods.

This study was carried out to investigate the correlation between root diameter and ginsenoside compositionof Panax ginseng C. A. Meyer cultivar Yunpoong. Dry matter ratio of main root was a little higher than that of lateral rootand fine root, and that was higher by the increase of root diameter in the same root parts. Total ginsenosides composition ofmain and lateral roots increased by the decrease of root diameter, especially in lateral root. Similar resulted in fine root, butthere was no significant difference where root diameter was below 2.5㎜. Except for ginsenoside-Rg1, other ginsenosidescomponent, PDs, PTs and total ginsenosides had highly negative correlation with the root diameter within whole root, mainroot+lateral root and lateral root+fine root, while Rg1 had positive correlation with the root diameter.
