Technology of obtaining iron complex based on polysaccharides from Аgaricus bisporus

It was developed the technology of obtaining the iron-containing complex based on polysaccharides from Agaricus bisporus. It included the two phase: extraction the polysaccharides and formation of the iron-containing complex. It was determined that the reasonable method of obtaining polysaccharides from raw materials is extraction with 3 % sodium hydroxide solution for 4 hours, followed by purification from non-carbohydrate substances. Galactoglucan dominated among the polysaccharides. The rational conditions for obtaining the iron-containing complex were the combination of ferric (III) chloride and polysaccharide solutions; concentrations of solutions were Fe3+ ? 0.075 %, polysaccharides ? 0.113 %; mass ratio of iron and polysaccharides ? 1.0 : 1.5, pH ? 11.5. The complex was stable in the aggressive media of the gastrointestinal tract, microbiologically safe and remained usable within 12 months of storage. It was an effective antianemic preparation.
