Summary:FIELD: organic chemistry, chemical technology. ^ SUBSTANCE: invention describes complexes of pectin biopolymer with dicarboxylic acids of the general formula (I): ^ wherein R means hydrogen atom (H), methyl group (Me); m = 18-50; a) X means -(CH2)2 or b) X means -CH=CH, and a method for preparing complex of pectin with dicarboxylic acid of the general formula (I). Method involves interaction of pectin aqueous solution of the formula (II): ^ wherein R means hydrogen atom (H), methyl group (Me); n = 98 heated to temperature 55-60°C with dicarboxylic acid - succinic or fumaric acid at heating taken in the amount 0.13-0.55 g of acid per 1 g of pectin, and formed complex is precipitated with ethyl alcohol and dried. Prepared complexes show less toxic effect and irritating effect on stomach mucosa as compared with free succinic and fumaric acids. ^ EFFECT: improved preparing method, improved and valuable properties of complexes. ^ 2 cl, 3 ex
