FIELD: chemistry.

SUBSTANCE: method is characterised by the fact that 100 mg of iron sulphate or zinc sulphate are dissolved in 1 ml of water and obtained mixture is dispersed into carrageenan solution in acetone, which contains 300 mg of carrageenan, in presence of 0.01 g of E472c preparation with mixing. After that, 2 ml of ethanol are added, obtained suspension is filtered and dried at room temperature, with realisation of the method without special equipment.

EFFECT: simplification and acceleration of the process of obtaining microcapsules and increase of output by mass.
