“…Regarding the physio-chemical quality of the extracted oils, it was observed that there is a significant difference between the genotypes, this finding was reported by several studies that indicated that the physicochemical quality of the oil varies according to several factors such as genotype, origin, harvest date, and extraction temperature (Seiquer et al, 2015;El Kharrassi et al, 2018;Mechqoq et al, 2021b;Ouchbani et al, 2021). Concerning the specific extinction (232 nm, 272, and DK) and peroxide index, results registered by the different samples were inferior to the limit fixed by the national norm related to the argan extra virgin oil (NM 08.5.090) and the same for the acidity index (Moroccan Standard, 2003;Rahmani, 2005).…”

“…Concerning the specific extinction (232 nm, 272, and DK) and peroxide index, results registered by the different samples were inferior to the limit fixed by the national norm related to the argan extra virgin oil (NM 08.5.090) and the same for the acidity index (Moroccan Standard, 2003;Rahmani, 2005). These different parameters enable the measurement of the primary and secondary oxidation compounds such as the conjugated dienes and trienes (Ouchbani et al, 2021), and the presence of these elements in high quantities prove the low quality of the samples and it is translated by a low aptitude for conservation (Boulfane et al, 2015).…”

The argan tree is an endemic plant of Morocco that plays a great socio-economical and ecological impact in the south of the country. This plant is well known for the oil extracted from the almond, characterized by high nutritional value and its large spectrum of uses. This study aims to evaluate the chemical composition and the physicochemical parameters of fixed oils produced by the argan trees introduced in Oujda City and to compare them with other oils produced by the same trees in their natural biotope in the northeast and southwest of Morocco. The obtained results indicated that the oil yield varies between 57.65% and 47.60%. The investigation of the chemical composition using HPLC-DAD showed the presence of three types of tocopherols: α-tocopherols (9.7%), δ-tocopherols (6.6%), and γ-tocopherols (83.6%), the total content of tocopherols vary between 323.86 and 553.12 mg/kg. While, the methyl esters analysis using GC-MS showed the presence of 4 main fatty acids: oleic acid (55.40–41.14%), linoleic acid (36.92–26.75%), palmitic acid (18.69–9.97%) and stearic acid (12.09–3.68). The physicochemical parameters (the free acidity, the peroxide value, and the specific extinction) indicated that the different tested oils are characterized by a good oil quality according to the Moroccan standard concerning argan oil (NM 08.5.090). The obtained results indicated that the introduced argan in Oujda City showed a quality and a chemical composition that was comparable to that produced in the natural area of the argan tree, which shows the plasticity the plant under different climatic and edaphic conditions. These results emphasize the encouragement of the introduction of this species at a high level in eastern Morocco.

“…In addition to solvents, other factors, such as temperature, could increase the yield. Recently, Ouchbani et al studied the effects of heating during the press-extraction process on the yield [ 7 ]. The highest yield values (53–55%) were obtained at 80 °C without compromising the quality of the oil.…”

“…The triacylglycerol (TAG) fraction constitutes the major one in Argan oil (around 99% of the saponifiable fraction) [ 7 ]. The major TAGs quantified in virgin Argan oil are di-oleoyl-linoleoyl-glycerol (OOL) (19.5%), di-linoleoyl-oleoyl-glycerol (LLO) (13.6%), palmitoyl-oleoyl-linoleoyl-glycerol (POL) (13.6%), tri-olein (OOO) (12.8%) and palmitoyl-di-oleoyl-glycerol (POO) (11.5%) [ 6 , 7 , 8 , 9 , 10 ].…”

“…Argania spinosa is a source of valuable oil, which is not only used as human food, but also in traditional medicine and in pharmaceutical and cosmetic preparations. Several studies demonstrated its pharmacological activities, such as blood pressure reduction [ 5 ], anti-inflammatory- [ 6 ], antiproliferative- [ 7 ], cardioprotective- [ 7 , 8 , 9 ], antidiabetic- [ 8 ], antioxidant- [ 10 ] and hypolipidemic- [ 8 ] activities. The production of Argan oil (AO) is of social, environmental and economic interest [ 11 ].…”

Quality Control and Authentication of Argan Oils: Application of Advanced Analytical Techniques

In addition to the nutritional and therapeutic benefits, Argan oil is praised for its unique bio-ecological and botanic interest. It has been used for centuries to treat cardiovascular issues, diabetes, and skin infections, as well as for its anti-inflammatory and antiproliferative properties. Argan oil is widely commercialized as a result of these characteristics. However, falsifiers deliberately blend Argan oil with cheaper vegetable oils to make economic profits. This reduces the quality and might result in health issues for consumers. Analytical techniques that are rapid, precise, and accurate are employed to monitor its quality, safety, and authenticity. This review provides a comprehensive overview of studies on the quality assessment of Moroccan Argan oil using both untargeted and targeted approaches. To extract relevant information on quality and adulteration, the analytical data are coupled with chemometric techniques.

In this study, a batch flow oil extraction system was used for extraction of oil from walnut (Juglans regia L.) and Sesamum (Indicum sesame). Sample mass (g), applied pressure (MPa), and processing temperature of oil (°C) were selected as independent variables and oil extraction mass percentage and oil analysis as dependent variables. Response surface methodology was employed for conducting statistical analysis, modeling, and data optimization. The results revealed that the highest percentage of oil extraction for walnut was obtained at a pressure of 10.5 MPa, a temperature of 31.5°C, and a sample weight of 8 g, with a value of 25.36%. Also, the highest percentage of oil extraction for Sesamum was obtained at the pressure of 13.88 MPa, the temperature of 31.5°C, and a sample value of 20 g with a value of 22.4%. Optimal level of independent variables for walnut and sesame were 8.03 g, 10.41 MPa, and 27.37°C; 20 g, 13.88 MPa, and 27°C, respectively. In this optimum condition, the amount of sesame and walnut peroxide was 10 ± 0.03 and 1.9 ± 0.07 (meq O2/kg), respectively. Likewise, the amount of acid for sesame and walnut was 1.53 ± 0.05 and 0.06 ± 0.02 g/%, separately. Linoleic acid (42.7–51.15), oleic acid (38.6–24.03), palmitic acid (10.87–8.21), and stearic acid (5.5–3.39) were the most common fatty acid components in sesame and walnuts, respectively.
