FIELD: food industry.
SUBSTANCE: invention relates to food industry. Disclosed is a method for producing agar, including its extraction from algae by ionic liquid, represented by the deep eutectic with melting point which is lower than 100 °C. At the end of the extraction process, the produced solution is being separated into algae residue and the agar solution in the deep eutectic, and alcohol is being added in the latter. Then, the hot solution is being filtered and separated into agar and alcohol-containing solution of the deep eutectic, from which the latter is regenerated and reused. Alga Ahnfeltia is used as an alga, preliminary cleaned from impurities, by electrohydraulic treatment in dilute alkali solution, then, inner steam destruction of algae thallomes is being performed, then, treated algae is being extracted by the deep eutectic. Alcohol, deep eutectic and water are being regenerated and reused, besides, the agar, produced by filtering, is being dehydrated.
EFFECT: invention ensures producing high-purity agar, and the process duration is considerably reduced.
