What are Arabinoxylan oligosaccharides?

Arabinoxylan oligosaccharides (AXOS) are prebiotic carbohydrates with promising health-promoting properties that stimulate the activity of specific colon bacteria, in particular bifidobacteria. However, the mechanisms by which bifidobacterial strains break down these compounds in the colon is still unknown.

Is oligosaccharide a prebiotic?

Oligosaccharides are a type of carbohydrate with prebiotic properties. Because of this, they may bring health benefits, such as an improved digestion and gut health.

What are probiotic oligosaccharides?

Oligosaccharides are a prebiotic fiber that contribute to healthy gut bacteria growth. A healthy balance of gut bacteria leads to an improved microbiome.

Is oligosaccharides a dietary fiber?

Only polysaccharides were included in dietary fiber originally, but more recent definitions have included oligosaccharides as dietary fiber, not based on their chemical measurement as dietary fiber by the accepted total dietary fiber (TDF) method, but on their physiological effects.

Is inulin an oligosaccharide?

Inulin is a mixture of oligo- and polysaccharides composed of fructose moieties joined by beta(2–>1) linkages in linear chains. Almost each chain ends with a glucose moiety. Oligofructose is a synonym for fructo-oligosaccharides, with fructose moieties joined by beta(2–>1) linkages, as in inulin.

Are oligosaccharides bad for you?

Oligosaccharides are considered high FODMAP foods. FODMAPs are short-chain carbs that can cause digestive issues for some people when fermented by gut bacteria. A diet high in FODMAPs has been shown to cause abdominal pain and bloating in people with irritable bowel syndrome (IBS) ( 13 ).

What is inulin fiber?

Inulin is a type of soluble fiber found in many plants. Inulin is also fructan. Like other fructans, it is a prebiotic, meaning that it feeds the good bacteria in the gut. Fructans are chains of fructose molecules. The molecules link together in a way that the small intestine cannot break down.

Is arabinoxylan soluble?

Arabinoxylans can be either water soluble or water insoluble, depending on a variety of factors such as molecular weight, arabinose:xylose ratio, and degree of diferulate cross-linking (Izydorczyk and Biliaderis 1995).
