Fructooligosaccharides (FOS) also sometimes called oligofructose or oligofructan, are oligosaccharide fructans, used as an alternative sweetener. FOS exhibits sweetness levels between 30 and 50 percent of sugar in commercially prepared syrups.

Feb 11, 2024 · FOS are short and medium-chain sugar molecules consisting of fructose units linked together. Your body is unable to digest these molecules directly. Instead, they serve as food for beneficial gut bacteria, aiding in digestion and overall gut health.

FOS is made of fructose molecules with one glucose molecule on the end, altogether of less than 10 simple sugars [1]. Short-chain FOS is defined as unbranched chains made of ≤9 fructose molecules [17]. Picture 1. Examples of foods high in fructooligosaccharides. FOS or oligofructose occurs naturally in significant amounts in [6,7]:

Jan 12, 2018 · Fructooligosaccharides (FOS) are a form of carbohydrate. While they may be generally considered safe to use, they may also cause certain side effects. These include cramps, nausea, and bloating....

Fructooligosaccharides (FOS) are oligomers of β (2-1)-linked D-fructose molecules with a maximum DP of 10. FOS can contain one molecule of glucose in their structure to form a linear chain linked to fructose (GFn) or only fructose (Fn) (Yildiz, 2011).

Jul 31, 2023 · Fructooligosaccharides (FOS) are oligosaccharides, a form of carbohydrate, made up of short chains of fructose molecules. Occurring naturally in various plants, such as onions, garlic, blue agave, bananas, and artichokes, FOS contributes to their sweetness.

Dec 20, 2022 · Fructooligosaccharides (FOS), oligofructans, or oligofructose are oligosaccharides of D-fructose (F) and a terminal D-glucose (G) molecule in which the fructosyl groups are linked by β-glycosidic bonds (2 → 1/6).

Fructo-oligosaccharide (FOS) is a plant carbohydrate storage molecule composed of 1–7 d-fructose subunits linked to a terminal d-glucose molecule. You might find these chapters and articles relevant to this topic.

Fructo-oligosaccharides (FOS) are polymers of fructose residues linked to a terminal glucose molecule. Enzymatically, FOS are synthesized from sucrose through a transfructosylating reaction catalyzed by β-fructofuranosidase (FFase) or fructosyltransferase (FTase) enzymes ( de la Rosa et al., 2019 ; Nobre, Gonçalves, Teixeira, & Rodrigues, 2018 ).

Fructo- oligosaccharides (FOS) are used in food applications, dietary supplements and nutrition bars as low-calorie sweetener for diabetes in replacement to sucrose, also used in pharmaceutical drugs and cosmetics products formulation.
