FIELD: food processing industry, in particular complex reprocessing of buckthorn berries.
SUBSTANCE: sea buckthorn berry refuse is sequentially extracted with water, liquid carbon dioxide and aqueous alcohol solution, and respective extracts are isolated. Extraction is carried out with separate feeding of water and alcohol, and in each step pressure is decompressed to provide extractant boiling and then is built up to origin value. Water extract is concentrated and blended with juice followed by clarifying and pre-packing. CO2-extract is pre-packed. Aqueous-alcohol extract is distilled to eliminate the alcohol; residue is subjected to vacuum freeze-drying and pre-packed. Solvent cake is dried, disintegrated and pre-packed.
EFFECT: decreased energy consumption and accelerated processing cycle.
