Influence of deep-eutectic and organic solvents on the recovery, molecular mass, and functional properties of dextran: Application using dextran film.

The novelty of this study is to examine the impact of different solvent systems, namely organic and deep eutectic solvents, on recovery yield, antioxidant activity, poly-dispersity index, and functional properties of microbial dextran. The optimized conditions for maximum dextran recovery were obtained using organic solvent found to be: supernatant: organic solvent - 1:4 v/v; organic solvents: ethanol, isopropanol, and acetone; temperature: 0 °C; and time: 16 h. Though a similar structure was obtained for dextran recovered using various solvents, the degree of branching varied, with DES-precipitated dextran having the highest branching of 20 % α-(1,3) linkages.
