Levan

Description:

Levan is a fructan, a type of polysaccharide primarily composed of fructose units linked by β(2→6) glycosidic bonds, with occasional branching. It is produced by certain bacteria and plants, notably from the fermentation of sucrose by specific strains of bacteria such as *Zymomonas mobilis* and *Bacillus subtilis*. Levan is characterized by its high molecular weight and solubility in water, forming a viscous solution. It exhibits prebiotic properties, promoting the growth of beneficial gut bacteria, and is often utilized in food and pharmaceutical applications due to its ability to enhance texture and stability. Additionally, levan has potential applications in drug delivery systems and as a thickening agent. Its unique structure allows it to form gels and films, making it valuable in various industrial processes. Overall, levan is recognized for its functional properties and health benefits, contributing to its increasing popularity in food science and biotechnology.

Levan - from Erwinia herbicola

CAS: 9013-95-0

Levan is a (2,6)-linked fructan produced by Erwinia herbicola. The polysaccharide contains branches every 10-12 fructose residues linked (1,2) and is reported to have a molecular weight in excess of 1000 KDa.  Potential industrial applications of levan have been proposed as an emulsifier, formulation aid, stabilizer and thickener, surface-finishing agent, encapsulating agent, and carrier for flavor and fragrances. In addition, levan is promising in medicine as a plasma substitute, drug activity prolongator and antihyperlipidemic agent.
