A fructan is a polymer of fructose molecules. They occur in foods such as:

• asparagus
• green beans
• leeks
• onions (including spring onion)
• wheat

There are 3 types of fructans:

1. Inulin - linear fructans generally linked by β(2→1) glycosidic bonds
2. Levan - linear fructans generally linked by β(2→6) glycosidic bonds
3. Graminan - branched fructans linked by both β(2→1) and β(2→6) glycosidic bonds
