Evaluation of Intestinal Immunity Activity by Steam-Heat Treatment and Fermentation of Lactic Acid Bacteria of Fruit and Vegetable Complex Extracts containing Red Ginseng

The purpose of this study was to investigate whether the activity of ginsenoside metabolites and the intestinal immunity antioxidant activity were remarkably improved by lactic acid bacteria fermentation by adding a small amount of ginsenoside to the complex extracts of fruits and vegetables. It was confirmed that the increase in intestinal immunity antioxidant activity due to synergistic effect was observed in the fruit-vegetable extract containing ginsenoside compared to the ginsenoside-only extract or the fruit-vegetable extract. Then, by adding ginsenosides by content, the concentration of ginsenosides that can obtain a synergistic effect according to the fermentation of lactic acid bacteria was determined. As a result, it was confirmed that a synergistic effect was exhibited when lactic acid bacteria were fermented and extracted by mixing ginsenosides in a mass ratio of 3 to 10% with respect to the mass of the fruit-vegetable mixture. As a result, when treated at a concentration of 200 ㎍/ml, the fruit-vegetable complex extract containing ginsenoside metabolites inhibited the generation of NO by about 60% compared to the complex extract containing no ginsenoside, The expression of IL-1β was suppressed by 63%, the expression of IL-6 by 69%, and the expression of TNF-α by 76%, confirming that the intestinal immune antioxidant properties were significantly improved.

홍삼함유 과채류 복합 추출물의 증숙열처리 및 유산균 발효에 의한 장관면역 활성

본 연구의 목적은 과채류 복합추출물에 소량의 홍삼을 첨가하여 증숙가열 및 유산균 발효에 의한 진세노사이드 대사산물의 활성 증가와 장내면역 활성이 현저히 개선되는지를 알아보고자 하였다. 홍삼 단독 추출물 또는 과채류복합추출물에 비해 홍삼을 함유한 과채류 복합추출물에서 시너지 효과에 의한 장내면역 활성의 증가가 관찰됨을 확인하였다. 다음으로 홍삼을 함량별로 첨가하여 유산균 발효에 따른 시너지 효과를 얻을 수 있는 홍삼의 농도를 결정하였다. 그 결과, 홍삼을 과채류 혼합물 질량에 대하여 3~10%의 질량비로 혼합하여 증숙 및 유산균 발효 추출하였을 때 시너지 효과가 나타나는 것을 확인하였다. 또한 홍삼을 함유한 과채류 복합추출물은 200㎍/ml의 농도로 처리하였을 때 홍삼이 함유되지 않은 과채류 복합추출물에 비해 NO 생성을 약 60% 억제하였으며, IL-1β의 발현은 63%, IL-6의 발현 69%, TNF-α의 발현 76% 수준으로 억제하여 장내면역 활성이 크게 향상되었음을 확인하였다.
