Corn dextrin

Corn dextrin is a soluble fibre derived from corn starch. It is produced by the partial hydrolysis of starch, a process that breaks down the long chains of glucose molecules into shorter ones. This process is typically achieved using enzymes or acids.

Manufacturers use corn dextrin primarily as a bulking agent, a texturiser, and a source of soluble fibre. It can also act as a carrier for flavours and colours. It is commonly found in snacks like crisps and sausages, as well as in some breakfast cereals and baked goods.

Corn dextrin is authorised as a food additive in Great Britain and is listed on the Register of Food Additive Authorisations. EFSA has evaluated it, and it is generally considered safe for consumption at typical levels. Some research suggests that soluble fibres like corn dextrin can contribute to gut health and may have a prebiotic effect, supporting beneficial gut bacteria. Evidence regarding its specific impact on blood sugar or satiety is still an area of ongoing research.
