FIELD: technological processes; chemistry.
SUBSTANCE: invention relates to a method of dextranal producing. Method envisages modification of dextran with molecular weight 20-75 kDa in the form of 5-25 % aqueous solution by mechano-activation processing initial dextran in apparatus with energy of activation of 16-85 kJ/mol. Preferably dextranal is extracted from its aqueous solution by ethanol and dried.
EFFECT: invention enables to obtain easily soluble derivative of dextran for pharmaceutical, cosmetic and food industries, eliminating harmful impurities and simultaneously eliminating loss of product.
