  • Can edible oils be extracted from hemp seed?
  • While the edible oils market hemp seed. Expeller pressing and organic solvent extractions are common methods for oil extraction in the food industry. However, these two methods come with some concerns, such as lower yields for expeller pressing and environmental concerns for organic solvents.
  • Can we extract oil from hemp seeds using supercritical CO2?
  • In this work, the possibility of extracting oil from hemp seeds using supercritical CO 2 was investigated. It is noted how the lipid profile remains optimal even in the presence of pretreatment with ultrasounds, which increases the extraction yield even if a slight green colouring is observable.
  • How is hemp oil produced?
  • Hemp oil is generally produced by solvent extraction or by cold pressing. The first type of extraction uses solvents, and for this reason is dangerous for the environment and can contain toxic residue. Thus, in the last few years, cold pressing has come to be preferred despite the lower yield of extraction [ 8 ].
  • Can hemp oil be extracted?
  • In this work, the hemp oil extraction process was studied, taking advantage of the supercritical CO 2 and ultrasounds, and comparing it with the exhaustive Soxhlet technique. The residual cake from extraction is a protein-rich waste that can be used for food formulations.
  • Does hemp seed oil have a high nutritional profile?
  • Particularly, the oil from hemp seeds has a high nutritional profile because of polyunsaturated essential fatty acids (EFAs) contained in this oil, which are linoleic acid (C18:2ω6) and α-linolenic acid (C18:2ω3) contained in the hemp seed oil at a ratio of 3:1 [ 4 ].
  • Why is hemp used in industrial production?
  • The hemp plant ( Cannabis sativa L.) is widely cultivated and used in industrial production because of its multi-functionality. It is possible to obtain isolated proteins, fibres for paper and textile, oil from seeds and flours either for food or for cosmetics and pharmaceutical industries [ 1, 2, 3 ].
