“…It presented an interesting contribution of ω-3 and ω-6 fatty acids that could be attractive for reformulating meat products [15,24]. Hemp oil (Cannabis sativa L.) is composed of a well-balanced fatty acids and antioxidant profile, is rich in polyunsaturated fatty acids, principally the omega-6 linoleic acid (55.41-56.94%) and contains gamma and alpha linoleic acids (0.64-1.10%, 16.51-20.40%) [25,26]. Buckwheat is a pseudo-cereal with a high nutritional quality known for being a dietary source of dietary fiber, vitamins, minerals, and antioxidants.…”

A gelled emulsion (GE) prepared with hemp oil and buckwheat flour was used to replace pork back fat in frankfurters. Five different formulations were prepared: control (with 35% pork back fat—SC), and the following four to achieve 25%, 50%, 75%, and 100% pork back fat substitution by GE (S1, S2, S3, and S4, respectively). Nutritional, technological, and sensorial characteristics of frankfurters were evaluated. Sausages containing GE presented a lower total fat content with a higher amount of polyunsaturated fatty acids, increased omega 3 content, and reduced saturated fat by up to 55%. The incorporation of GE did not significantly modify technological properties such as emulsion stability or lipid oxidation in spite of using vegetable oils highly susceptible to oxidation. The reformulation of the frankfurters presented a greater effect on the texture and sensory properties when GE was used as total substitution for the pork back fat (S4). When GE was used only as partial substitution for the pork back fat, sausages similar to control frankfurter were obtained. So this study demonstrated that the use of GE could be a promising strategy in the reformulation of healthier meat products.

“…Additionally, previous studies have shown that liquefied DME can extract a variety of functional substances, such as astaxanthin [50,51], fucoxanthin [52], lutein [29,53], resveratrol and its glycosides [54], catechins and caffeine [55], tocopherol [56], gingerols and capsaicin [27]. Among these substances, carotenoids, such as astaxanthin, fucoxanthin and lutein, are hydrophobic, therefore difficult to encapsulate into liposomes by mechanical methods.…”

We investigated a method to prepare liposomes; soy lecithin was dissolved in liquefied dimethyl ether (DME) at 0.56 MPa, which was then injected into warm water. Liposomes can be successfully prepared at warm water temperatures above 45 °C. The transmission electron microscopy (TEM) images of the obtained liposomes, size distribution, ζ-potential measurements by dynamic light scattering and the amount of residual medium were compared by gas chromatography using the conventional medium, diethyl ether. The size of the obtained liposomes was approximately 60–300 nm and the ζ-potential was approximately −57 mV, which was almost the same as that of the conventional medium. Additionally, for the conventional media, a large amount remained in the liposome dispersion even after removal by depressurization and dialysis membrane treatment; however, liquefied DME, owing to its considerably low boiling point, was completely removed by depressurization. Liquefied DME is a very attractive medium for the preparation of liposomes because it does not have the toxicity and residue problems of conventional solvents or the hazards of ethanol addition and high pressure of supercritical carbon dioxide; it is also environmentally friendly.

“…Pressurized extraction technologies, classified as green extraction, avoid harmful organic solvents and are increasingly favored for extracting plant materials and other natural products. − In particular, subcritical pressurized conditions, where liquefied dimethyl ether (DME) is used as a solvent, allow to successfully extract water, oils, lipids, and specific organic compounds from various natural sources. − The subcritical dimethyl ether extraction (SDMEE) is operated by introducing commercial liquefied DME into a reactor via its vapor pressure at low or room temperature. − No reports exist on the use of DME in the subcritical fluid extraction of triterpenoids from CRs. However, in a previous study, triterpenoid saponins have been extracted from Centella asiatica (L.) Urb., which suggests the potential of SDMEE for extracting triterpenoids from CRs.…”

Cannabis sativa L. (Cannabaceae) is an important medicinal plant known for its versatile applications. While most plant parts are extensively used, cannabis roots (CRs), which contain a diverse array of bioactive metabolites (particularly triterpenoids such as friedelin and epifriedelanol) have often been overlooked and remain underutilized. Little effort has been made to develop green extraction methods to isolate these bioactive compounds from CRs. This study aimed to investigate the potential of the subcritical dimethyl ether extraction (SDMEE) and subcritical water extraction (SWE) methods for extracting triterpenoids from CRs. Multiple extraction techniques were applied to CR samples obtained from the hemp strain [Siam CA]. Subsequently, the most promising method was optimized using response surface methodology (RSM) with a central composite design (CCD). The results indicated that water−Soxhlet extraction and SWE failed to isolate any triterpenoids from the CR sample.In contrast, the SDMEE method demonstrated a chemical profile similar to that obtained using conventional solvents and was subsequently selected for optimization using RSM with CCD. The optimal conditions were achieved using DME with water as cosolvent at 80:20 w/w and a temperature of 40 °C, which resulted in a higher triterpenoid yield than that obtained via chloroform and ethanol−Soxhlet extraction. These findings suggest that the SDMEE method holds great potential for green extraction, enhancing the value of CRs and presenting opportunities for various industrial triterpenoid applications.
