Study of different extraction processes for hemp



Different processes were compared for the extraction of hemp oil.

SFE, Soxhlet, percolation, sonication, pyrolysis & treated processes were compared.

Comparisons were conducted in terms of physical, chemical & economic aspects.

Central composite design was used to optimize the SFE & sonication parameters.

SFE were observed as economical process followed by Soxhlet.


Hemp (Cannabis sativa) seed oil is a rare source of nourishment for vegetarian diets due to the unique ratio of ω-6/ω-32(>0.93). The maximum yield of 37.30% was estimated through ultrasonication treated Soxhlet process.
