“…This relatively high ratio would be considered favorable for reducing blood cholesterol and preventing cardiovascular disease [32]. Moreover, the results of our study indicate that the ratio of omega-6 to omega-3 acid in hemp seeds is 3/1, this results were in accordance with this reported in the literature [21,30], which is widely regarded as a ratio highly beneficial to human health [14,22].…”

Cannabis sativa L. (hemp) seed oil is known for their food use, is the amount of polyunsaturated fatty acids from hemp seeds that would make these interesting products. The yield and the chemical characterization of three varieties of non-drugs hemp oil cultivated in Morocco were determined. Three varieties were used, namely, Santhica 27, Futura 75, and Epsilon 68 listed in the French and European catalogs. The chemical composition of all varieties from hemp oils was determined using gas chromatography-mass spectrometry method. The oil content of the hemp seeds ranged between 30.45% and 34.93%. Among the 09 detected fatty acids, a high level of linoleic acid (omega-6) was recorded between 56.71 ± 0.1% and 57.70 ± 0.1%, α-linolenic acid (omega-3) ranged from 13.66 ± 0.04% to 14.80 ± 0.06%, and the oleic acid ranged from 12.80 ± 0.04% to 13.30 ± 0.03%. Moreover, palmitic, stearic, and arachidic acids contents varied between 7.32 ± 0.02% (Futura 75) to 7.70 ± 0.03% (Santhica 27), 2.40 ± 0.02% (Futura 75) to 2.60 ± 0.04% (Epsilon 68), and 0.9% for all varieties, respectively. These results show that the hemp seeds cultivated in Morocco could be used as a source of food, characterized by high nutritional value.

“…Regarding the fatty acid profile, the oils obtained by SFE have almost the same fatty acid composition than the raw materials. This absence of selectivity of SFE towards specific triglycerides as measured by the fatty acid composition was also observed in literature on various raw materials (Da Porto et al, 2012a;Martinez et al, 2008). Peroxide value determination was performed on all F0 oily fractions except for poppy whose oily fraction was solid and of too low volume to allow measurements.…”

“…Linseed, poppy and sesame exhibited lipid yield in the range of 87-92%. These yields were higher than the majority of those reported for lipid extraction by neat CO 2 from same seeds Temelli, 2002, 2003;Corso et al, 2010;Da Porto et al, 2012a, 2012b.

“…Supercritical extraction has already been investigated for these five seeds and nut, and the studies generally focused on the effect of process parameters (namely pressure, temperature and flow rate) on extraction yield (on sesame (Corso et al, 2010;Döker et al, 2010); on hemp (Da Porto et al, 2012a, 2012b; on poppy (Bozan and Temelli, 2003); on walnut (Oliveira et al, 2002;Salgin and Salgin, 2006)). For instance, on linseed, SFE optimization (Bozan and Temelli, 2002;Ivanov, 2012;Jiao, 2008;Özkal, 2009;Rombaut, 2013) showed that an increase of temperature and pressure increased the oil yield.…”

-In a context of a strong demand for vegetable oils, the development of new "green" processes is essential to provide methods that avoid the use of organic solvents, work at relatively low temperatures and preserve the quality of the final products. The supercritical fluid extraction (SFE) process meets these objectives. In this study, five meals (hemp, flax, sesame, poppy and walnut) were subjected to SFE at 45• C and 250 bar in the presence of ethanol as co-solvent. Using this method, between 77 and 98% of the lipids present in the meal could be extracted. Except for poppy, 50% of the lipids present in the cake were recovered as a separate oily liquid phase. SFE was not selective toward certain types of triglycerides: the oils obtained exhibited the same fatty acid profile than the total lipid extracts from the cakes. In contrast, the composition in minor lipid components was dependent on the type of meal investigated. For example, hemp lipid extract was particularly rich in chlorophyll.Keywords: Supercritical fluid extraction / press cake / oil recovery / oil quality Résumé -Technologie à base de CO 2 pour l'extraction d'huiles de tourteaux de pressage. Dans un contexte de forte demande en huiles végétales, le développement de nouveaux procédés « verts » est indispensable pour proposer des procédés évitant l'utilisation de solvants organiques, travaillant à relativement basse températures et préservant les qualités nutritionnelles et organoleptiques des produits finaux. Le procédé d'extraction par fluide supercritique (EFS) répond à ces objectifs. Dans cette étude, cinq tourteaux végétaux (chanvre, lin, sésame, pavot et noix) ont été soumis au procédé d'EFS à 45• C et 250 bar en présence d'éthanol comme co-solvant. Ce procédé a permis d'extraire entre 77 et 98% des lipides présents dans les tourteaux. À l'exception du pavot, 50% des lipides présents dans les tourteaux se retrouvent sous la forme d'une phase liquide huileuse indépendante. L'EFS n'est pas sélective vis-à-vis de triglycérides particuliers. En effet, l'huile extraite a le même profil en acides gras que les lipides totaux du tourteau. Néanmoins, selon la nature du tourteau considéré, la composition en composés lipidiques mineurs est très variable. Par exemple, la quantité de chlorophylle extraite est très importante dans le cas du tourteau de chanvre.

ABSTRACT:The aim of this study was to evaluate the effect of dietary supplementation with hemp seed oil (HSO) on the lipid metabolism, through the plasma lipid profile, liver function and concentrations of fatty acids (FA), cholesterol, and vitamin A in goat milk. Ten Carpathian goats were divided into two groups: one was fed the control diet (C) composed of alfalfa hay and concentrate, and the other was fed C diet supplemented with 93 g/day of HSO (4.7% of dry matter intake) for 31 days. The HSO supplementation did not modify plasma cholesterol, triglyceride or phospholipid concentrations, or the activities of alanine aminotransferase or γ-glutamyltransferase, but plasma total lipid concentration was increased. HSO supplementation had no effect on milk yield, but it increased milk fat and protein contents. HSO supplementation markedly altered milk FA composition, but had no effect on milk cholesterol or vitamin A concentrations. Changes in milk FA composition corresponded to a decrease in saturated de novo synthesized FA (10:0-16:0) and an increase in 4:0, 18:0, and polyunsaturated FA concentrations. Also, HSO supplementation strongly increased cis-9,trans-11-CLA and also trans-18:1 concentrations in milk fat. These findings suggest that HSO can be used to modify milk FA content with a putative positive effect on human health, without adversely affecting goat performance or health, except for a potential hyperlipidemic effect.
