Many people with irritable bowel syndrome try to limit foods high in fructans to reduce bloating.

After analyzing the syrup, we found that the predominant carbohydrate was a fructan with a degree of polymerization of around twelve.

Researchers discovered a novel fructansucrase that efficiently synthesizes long-chain fructans from sucrose.

Fructansucrases produced by certain bacteria catalyze the formation of levan from sucrose.
