Levan as a Raw Material: Summary
Carbon is the backbone of the chemical industry. As the price of petroleum products rises, interest grows in products derived from bio-based materials. It is hoped that a biorefinery will eventually be able to substitute bio-products for those made from petrochemicals. Levan is one of those bio-based raw materials that can be used as the starting point for several useful products.
Levan (Levana™) is made by fermentation of sucrose. Several examples have been found in which levan can be substituted for chemicals with a poor eco-profile. Levan can be made into a biodegradable plastic film and it can be used as an adhesive. Levan derivatives have potential as surfactants. The safety of levan is particularly attractive for use in personal care products.
