FIELD: chemistry.
SUBSTANCE: invention relates to the field of chemistry, namely to a method for producing phytosterols of high purity. The method includes the dissolution of a concentrate of neutral substances of tall oil in a mixed solvent consisting of saturated hydrocarbon – hexane or heptane, monoatomic aliphatic alcohol – isopropyl alcohol or isobutyl alcohol, and water, at a certain content of solvent components and a certain ratio of the concentrate of neutral substances of tall oil and the mixed solvent, further, cooling of the resulting solution to 35-47°C is carried out, and it is held at a certain temperature for crystal maturation, pure sterol crystals are separated from the mother liquor, washed and dried.
EFFECT: invention provides for a method for producing phytosterols of high purity of the required quality, suitable for use in the food industry.
