Dextran


Dextrans, which are produced from sucrose by numerous lactic acid bacteria, are polymers composed exclusively of D-glucose with predominance of alpha-1,6-linkages.

Commercial dextran preparations are manufactured through partial hydrolysis, fractionation and purification of native dextran produced by a strain of Leuconostoc mesenteroides. Their structural feature is a high degree of linearity with more than 90% 1,6-linkages and a small number of side chains. Unlike similar polysaccharides such as starch and cellulose, dextrans are very soluble in cold water.

Dextrans have a variety of uses for pharmaceuticals, cosmetics, photographic industries, etc. and most of our products are manufactured in conformity to pharmaceutical GMP. Meito Sangyo has been manufacturing dextrans and dextran derivatives since nearly five decades ago, and is the only manufacturer of dextran in Japan and one of the major suppliers in the world.
