Overview

Dextran a multi-use, branched glucan with long, hydrophilic spacer arms that improve the performance of immobilized proteins acting on macromolecules. Low molecular weight dextran is useful as a stabilizer, volume extender, lubricant, binding platform, and matrix component. Higher molecular weight dextrans have differing viscosities, aggregation and permeation properties.
A multi-use, branched glucan

Dextran (mol. wt. 80,000) belongs to the family of neutral polysaccharides,which are recognized as contaminants in sugar processing and other food production industries. These are composed of chains of D-glucose units connected by alpha-(1-6) linkages of varying lengths.They are found as bacterial extracellular polysaccharides and reportedly synthesized from sucrose by beneficial lactic acid bacteria, such as Leuconostoc mesenteroides and Lactobacillus brevis. They are incorporated in bakery products to improve the crumb texture, softness, and loaf volume, as stabilizers and additives in confectionery, flavor extract, icing compositions, beverages including soft drinks, milk, etc.
