This study examined the improving effect of DFA IV obtained from bacterial fermentation on the gut health. The effects of the dietary DFA IV on the intestinal mass, short chain fatty acids production and pH were evaluated in vivo. Sprague-Dawley rats were fed the 0% (control) or 1% DFA IV supplement...

DFA Ⅳ의 생산방법은? | DFA Ⅳ (2,6':6,2' difructose dianhydride Ⅳ)는 과당중합체 (fructose polymer)인 레반 (levan)이나 이눌린(inulin)을 원료물질로 하여 화학적 또는 효소분해 방법으로 생산된다(Fig. 1). | |
난소화성의 비전분성 다당류의 특징은? | 난소화성의 비전분성 다당류(nonstarch polysaccharides)는 인체의 소화효소에 의해 분해되지 않고 대장에 도달하여 장내 미생물에 의하여 대사되어 장내미생물 군총과 대사산물의 조성에 큰 변화를 조성한다[1]. | |
Difructose dianhydrides가 사용될 수 있는 곳은? | Difructose dianhydrides (DFAs)는 2개의 과당(fructose)이 환원형 말단에서 결합된 고리형(cyclic) 이당류로, 결합의 종류에 따라 현재까지 DFA Ⅰ, Ⅱ, Ⅲ, Ⅳ, Ⅴ로 5종이 밝혀져 있다. DFAs는 구조적인 특징으로 인해 동물의 체내에서 분해되지 않는 비소화성 이당류로, DFA Ⅲ, Ⅳ는 설탕의 50% 정도의 감미를 가지며 체내에 흡수되지 않기 때문에 설탕의 대체하는 저칼로리 감미료로 사용될 수 있다[2]. 또한 DFAs는 생체 내에서 금속이온인 칼슘, 철분 등과 쉽게 복합체를 형성하여 소장에서의 흡수를 용이하게 할 수 있기 때문에 무기질 흡수를 촉진하는 기능성 식품에도 활용할 수 있다[2]. |
