METHOD FOR PRODUCING CIS-DIOL-FURANOSE-FRUCTOSE BORATE COMPLEXES AND CIS-DIOL-FURANOSE-RIBOSE BORATE COMPLEXES

摘要

The invention relates to a method for producing cis-diol-furanose-borate complexes used as nutritional supplements. According to the invention, the method consists in hot dissolving 3...5 moles of fructose in 72...76 moles of water, adding 1.8...2.2 moles of boric acid, the solution being heated to 58...65°C for 55...65 min while stirring, then introducing 1 mole of metal hydroxide at a pH of 8...8.5, the mixture being kept at the same temperature for 1 h, then it being filtered and lyophilized, thereby resulting a product which can be used as such or included in food products.
