What is "fructan"

n. (context carbohydrate English) Any polysaccharide composed of fructose residues

A fructan is a polymer of fructose molecules. Fructans with a short chain length are known as fructooligosaccharides. Fructans occur in foods such as agave, artichokes, asparagus, leeks, garlic, onions (including spring onions), yacón, jícama, and wheat.

Fructans also appear in grass, with dietary implications for horses and other grazing animals ( Equidae).
