Oligofructose syrup

Oligofructose syrup is a viscous liquid sweetener made from chicory root. The plant's natural inulin fibre is hydrolysed to produce shorter-chain fructose molecules, which are then purified and concentrated into a syrup.

Manufacturers add oligofructose syrup as a low-calorie sweetener and to improve texture and mouthfeel. It is often found in cereal bars, baked goods, and confectionery as a sugar replacer.

Oligofructose syrup is authorised as a food additive in Great Britain and is listed in the Register of Food Additive Authorisations. It is considered a source of dietary fibre, and some research suggests it may act as a prebiotic, supporting gut bacteria. EFSA has evaluated oligofructose and its derivatives. Evidence on its effects on blood sugar and gut health is generally positive at typical consumption levels, though some individuals may experience mild digestive discomfort.
