“…This variation can in uence the physical and chemical properties of oilcakes, thus in uencing their use in industrial applications. However, these ndings are in harmony with the results declared by [15,64] in ARPC and ALPC, respectively. The second-highest concentration of saturated fatty acid is stearic acid (C18: 0), which is present in the samples analysed in varying proportions, when SEPC, ARPC and SFPC oils stand out here with a signi cant content (5.95 ± 0.28 ; 5.78 ± 0.01 ; 5.22 ± 0.20 g/100g) respectively.…”

“…Whereas the last value of this fatty acid was registered in ARPC oil (0.10 ± 0.01 g/100g). The obtained results in ARPC, SEPC and SFPC are higher than those reported in other studies conducted by [15,58,69] respectively. In terms of abundant sterol (β-sitosterol), ALPC oil is similar to Ziziphus lotus almonds (71.99 ± 0.82%) [19] and to almond germplasm (72.4-73.9%) [73].…”

“…Oil cake is considered a signi cant source of proteins, bers, and minerals, primarily used as animal feed [7]. Numerous studies have encouraged and explored novel applications for by-products from the oil industry, including the formulation of functional drinks [8], preparation of naturally gluten-free our [9], food additives [10], emulsion stabilizers [11], sources of essential fatty acids [12], manufacturing of adsorbents, extraction of bers like nanocellulose [13] manufacturing of biocomposite [14], bioenergy production [15], protein-based lm matrix [16], and many others use.…”

Purpose : The oil industry generates substantial quantities of oilcake. These residues are traditionally used in many domains for multiple purposes. In order to explore other potential uses of these by-products, a comprehensive physicochemical characterisation was conducted. Methods : The analysis encompassed various parameters, including mineral profiling, protein content, fiber content, fatty acid composition, sterol content, total polyphenol, total flavonoid content, and antioxidant activity in argan, almond, sesame, nigella, sunflower, and soybean press cake. Results : Results indicated that potassium (K), phosphorus (P), magnesium (Mg), calcium (Ca), and sodium (Na) constituted the primary mineral elements in the studied oilcake. Regarding protein content, argan and soybean press cakes contained the highest level of 45.90±0.10 and 44.85±1.10 g/100g, respectively, while nigella and sunflower press cakes had the lowest protein content of 25.62±1.99 and 26.43±2.06 g/100g, respectively. The fatty acid composition revealed that the residual oils extracted could present beneficial properties, as they are rich in unsaturated fatty acids. Nigella press cake oil has a high oleic acid content (67.65%), while Sunflower press cake oil is richest in linoleic acid (54.17%). Sunflower press cake outperformed in total phenolic and flavonoid content, with registered values of 9.82 mg GAE/g and 15.44 mg QE/g, respectively. Additionally, sunflower press cake demonstrated the highest DPPH and FRAP antioxidant activity, and the values were 34.05 and 8.90 mg AAE/g, respectively. Conclusion : The findings suggest that oilcake could be considered as a rich nutrient source and their extracts exhibit substantial potential for added value, warranting focused attention in future research and development.

Argan oil is considered a relatively international product exported from Morocco, although different companies in Europe and North America distribute argan oil around the globe. Argan oil is non-refined vegetable oil, of the more well-known “virgin oil” type, is produced from the argan tree [Argania spinosa (L.) Skeels]. The argan tree is deemed to be an important forest species from both social and economic standpoints. Argan oil has rapidly emerged as an important product able to bring more income to the local population. In addition, it also has important environmental implications, owing to its ability to stand against desert progression. Currently, argan oil is mainly produced by women's cooperatives in Morocco using a semi-industrial mechanical extraction process. This allows the production of high-quality argan oil. Depending on the method used to prepare argan kernels, two types of argan oil can be obtained: food or cosmetic grade. Cosmetic argan oil is prepared from unroasted kernels, whereas food argan oil is achieved by cold pressing kernels roasted for a few minutes. Previously, the same food argan oil was prepared exclusively by women according to a laborious ancestral process. Extraction technology has been evolved to obtain high-quality argan oil at a large scale. The extraction process and several accompanying parameters can influence the quality, stability, and purity of argan oil. In view of this, the present review discusses different aspects related to argan oil chemical composition along with its nutritional and cosmetic values. Similarly, it details different processes used to prepare argan oil, as well as its quality control, oxidative stability, and authenticity assessment.

“…When plants (from the second Graphical Abstract generation) are used for biodiesel production, approximately 70-80% of the whole production cost is associated with its harvesting and processing (Adhikaria et al 2021). Biodiesel produced from microbes is categorized in third-generation biofuels (Allen et al 2018;Hossain and Mahlia 2020;Zhang et al 2020a, b;Zeghloulia et al 2021). The fourth-generation was recently introduced in which photobiological solar fuels, electro-fuels and synthetic cells are used for biodiesel production (Singh et al 2020).…”

Due to continuously increasing population, industrialization, and environmental pollution, lead to generating high energy demand which suitable for our environment. Biodiesel is an alternative renewable fuel source. According to the feedstock of production, biodiesel has been categorized into four generations. The main disadvantage of the first and second generation is the raw material processing cost that the challenge for its industrial-level production. Oleaginous bacteria that contain more than 20% lipid of their cellular biomass can be a good alternative and sustainable feedstock. Oleaginous bacteria used as feedstock have numerous advantages, such as their high growth rate, being easy to cultivate, utilizing various substrates for growth, genetic or metabolic modifications possible. In addition, some species of bacteria are capable of carbon dioxide sequestration. Therefore, oleaginous bacteria can be a significant resource for the upcoming generation’s biodiesel production. This review discusses the biochemistry of lipid accumulation, screening techniques, and lipid accumulation factors of oleaginous bacteria, in addition to the overall general biodiesel production process. This review also highlights the biotechnological approach for oleaginous bacteria strain improvement that can be future used for biodiesel production and the advantages of using general biodiesel in place of conventional fuel, along with the discussion about global policies and the prospect that promotes biodiesel production from oleaginous bacteria.
