Supercritical extraction and fractionation of natural compounds is one of the early and
most studied applications in the field of supercritical fluids. Fractionation of the oil is
very important for producing products with physical or nutritional properties of
interest to the food industry.
Supercritical CO2 was carried out at handmade supercritical fluid extraction system
where almost completely oil was extracted from hemp seeds and the obtained oil had
higher tocopherol content compared to cold pressing. Low temperatures of extraction,
reduced energy consumption, high product quality and absence of solvent in extracts
are numerous advantages than supercritical fluid extraction technique can provide as
opposed to traditional methods of extraction
