This study was carried out to investigate the dose-response of chitooligosaccharide (with a molecular weight of 1~3 kDa) on antimicrobial activity and lipid lowering functions in rats. Sprague-Dawley male rats were given experimental diets containing 0 (control), 0.5, 2, or 5% chitooligosaccharide (...

키토올리고당은 무엇으로 만든 물질이며 그 성질은? | 키토올리고당은 갑각류의 껍질 성분인 키틴으로부터 아세틸기를 제거하여 생성된 키토산을 효소 처리하여 만든 중 합도 2~10 DP의 올리고당으로서 수용성을 띠며 점도가 낮은 성질을 가진다(1). 현재 국내에서 식품의약품안전청은 키토산과 키토올리고당을 묶어 콜레스테롤 개선 효능을 가진 건강기능성분으로 인정하고 있으며, 일일섭취량을 1. | |
키토올리고당은 어떤 생리활성을 갖는가? | 5 g으로 설정하였다(2). 키토올리고당은 콜레스테롤 개선효과 외에도 항균활성(3), 항당뇨 효과(4), 비만억제(5), 면역능 활성(6), 항산화능(7), 암세포 성장 억제효과(8) 등 다양한 생리활성을 가지며, 최근 Xia 등(9)은 키토산과 키토올리고당의 생리활성을 자세하게 고찰하였다. | |
흰쥐에서 저분자량 키토올리고당이 장내 미생물에 미치는 항균활성과 지질 개선에 관한 용량-반응 효과를 조사한 결과, 체중 증가량과 식이섭취량이 가장 낮은 첨가군은? | 실험식이 5주째에 장 통과시간을 측정하였고, 신선한 분변을 취하여 장내 균수를 측정하였으며, 희생 후 혈장 지질, 간 지질, GPT 활성, 분변 지질을 측정하였다. 체중 증가량과 식이섭취량은 COS 5% 첨가군에서 유의하게 낮았다. 분변 중 bifidobacteria, lactobacilli, bacteroides, total anaerobes, total aerobes 수는 대조군, COS 0. |
