“…The extraction yield increased with increasing extraction pressure as consequence of the increase of the solvent density, which could enhance the solvent power and leads to the increase solubility of the extract. The same results have been reported by many authors (Perakis, Louli, Voutsas, & Magoulas, ; Sodeifian, Sajadian, & Saadati Ardestani, ). The main effect plot of pressure (Figure ) confirms the positive effect of pressure on the extraction yield.…”

An experimental extraction of Algerian date stones oil was carried out using supercritical carbon dioxide. Response surface methodology was used to investigate the effect of pressure (150–250 bar), temperature (313–333 K) and particles diameter (0.3–0.9 mm) on the extraction yield. The comparison of the predicted results with the experimental values confirmed the reliability of this technique. The optimum yield value was determined around 14.26% and was obtained at a pressure of 250 bar, a temperature of 333 K and particles diameter of 0.3 mm. the conventional solvent extraction using Soxhlet apparatus shows that the oil content of the date stones sample was about 16.22%. The fatty acids composition was determined using GC‐FID analysis, showing that the oleic acid was the major compound present in this oil. Practical applications Locally date stones are an abundant waste product of date processing industries which are rich in many valuables substances such as carbohydrates, oil, dietary fibers, vitamins, proteins, bioactive polyphenols and natural antioxidants, making them an attractive source for the extraction of bioactive compounds because of their low cost and high nutrient content. They can be used in many applications like the production of caffeine‐free coffee, food products formulation, cosmetics, and functional and medicinal supplements. They are a by‐product that can be easily collected and recycled in an economic and sustainable way. Also date stones oil is a great source of saturated, monounsaturated and polyunsaturated fatty acid acids which have several good human health benefits. The use of supercritical carbon dioxide extraction of date stones oil can be regarded as a great opportunity to develop the production of high quality date stones oil and exploit all the mentioned important properties.

“…Essential oils could be extracted from different plant organs by different extraction methods [7,8]. In recent decades, investigations in new technologies have led to the emergence of new innovative and more efficient extraction processes [9][10][11]. Essential oils have been used since ancient times in various cultures for medicinal and health purposes such as antibacterial, antiviral, antifungal, anticarcinogenic, antimutagenic, anti-inflammatory and antioxidant.…”

Essential oils are of paramount importance in pharmaceutical, cosmetic, agricultural, and food areas thanks to their crucial properties. However, stability and bioactivity determine the effectiveness of essential oils. Polymeric nanoencapsulation is a well-established approach for the preservation of essential oils. It offers a plethora of benefits, including improved water solubility, effective protection against degradation, prevention of volatile components evaporation and controlled and targeted release. Among the several techniques used for the design of polymeric nanoparticles, nanoprecipitation has attracted great attention. This review focuses on the most outstanding contributions of nanotechnology in essential oils encapsulation via nanoprecipitation method. We emphasize the chemical composition of essential oils, the principle of polymeric nanoparticle preparation, the physicochemical properties of essential oils loaded nanoparticles and their current applications.

“…Paviani et al [ 53 ], when adding 15% ethanol as a cosolvent to obtain extracts of green propolis (extraction conditions 50 °C and 250 bar), obtained an increase of 43.7% compared to the same process without the use of a cosolvent. The influence of the addition and concentration of cosolvent on supercritical CO 2 extraction was also shown for other natural matrices [ 62 ], demonstrating the importance of these modifiers to improve the extraction capacity of polar compounds. Cruz et al [ 63 ] showed that the presence of hydrated ethanol (1/1, v / v ) significantly increased the extraction yield of yacon leaves, obtaining extracts with higher antioxidant activity compared to extraction without the use of cosolvent, leading to higher yields.…”

The objective of this study was to determine the best operational conditions for obtaining red propolis extract with high antioxidant potential through supercritical fluid extraction (SFE) technology, using carbon dioxide (CO2) as the supercritical fluid and ethanol as the cosolvent. The following parameters were studied: overall extraction curve, S/F (mass of CO2/mass of sample), cosolvent percentage (0, 1, 2 and 4%) and global yield isotherms as a function of different pressures (250, 350 and 450 bar) and temperatures (31.7, 40 and 50 °C). Within the investigated parameters, the best conditions found were an S/F of 131 and the use of ethanol at the highest concentration (4% w/w), which resulted in higher extract yields and higher content of antioxidant compounds. Formononetin, the main biomarker of red propolis, was the compound found at the highest amounts in the extracts. As expected, the temperature and pressure conditions also influenced the process yield, with 350 bar and 40 °C being the best conditions for obtaining bioactive compounds from a sample of red propolis. The novel results for red propolis found in this study show that it is possible to obtain extracts with high antioxidant potential using a clean technology under the defined conditions.
