“…These results were more pronounced for pressures higher than 10 MPa. Peng et al (2020) studied the optimum extraction time for Roselle seed oil and found a similar tendency. Al‐Asheh et al (2012) also reported that a longer extraction time enhanced the recovery of a monoterpene, due to the leaching of heavier compounds.…”

In 2020, approximately 19.14 million tonnes of crude palm oil (CPO) was produced in Malaysia (MPOB, 2020). Typically, 4% (w/w) of CPO is in the form of palm fatty acid distillate (PFAD), which is recoverable as a by-product from the physical refining process (Estiasih & Ahmadi, 2018;Gapor Md Top, 2010). Fatty acids and glycerides are the major components (96.1%) of PFAD; these are commonly used in nonfood industries, within animal feed, laundry soap, biodiesel, and oleochemicals (Akinfalabi et al., 2019;Estiasih & Ahmadi, 2018;Gapor Md Top, 2010). Oil can be lost at various stages of the refining process. In addition, oil can be trapped in the by-product during palm oil milling. Consequently, vitamin E (0.48%), sterols (0.37%), squalene (0.76%), and volatile substances (0.71%) are valuable minor compo-

“…was dependent on high temperature condition to enhance the extraction rate probably due to (Maran et al., 2015). Peng, Mohd‐Nasir, Setapar, Ahmad, and Lokhat (2020) also found that the high‐pressure and low temperature gives the significant effect to obtain high solubility of roselle seed oil. However, the alleviation of solubility is relied by the enhancement of temperature due to the low density of ScCO 2 .…”

Peanut (Arachis Hypohea) skin as a by-product is peeled out due to reducing the quality of peanut butter. Peanut skin contains flavonoid and phenolic compounds that they retard oxidative degradation of lipids and thereby improve the quality and nutritional value of food. Peanut skin extract commonly can be anti-allergenic, antiviral, anti-inflammatory, anticarcinogenic activities, and also prevention of

“…SFE also applicable for the separation of heat‐labile compounds since the system is operate at moderate temperature and pressure. In other studies, SFE is proven to give better quality of desired constituents even though the yield is lower than conventional solvent extraction (Peng et al., 2020; Putra et al., 2018). Besides, the properties of supercritical fluid, higher diffusivity and lower density, surface tension, and viscosity, can be altered by manipulating the operating conditions (pressure and temperature), which provide more effective extraction process (Lee et al., 2013; Putra, Rizkiyah, Idham, et al, 2020).…”

The aims of this study were to optimize the supercritical carbon dioxide extraction conditions on the extraction yield and hydrolyzable tannins content of Quercus infectoria (QI) galls and determine the bioactivities of the gall extracts related to wound healing. Experimentally, the QI gall was extracted using the supercritical carbon dioxide (SC‐CO2) extraction method at different operating conditions which were pressure (20 to 30 MPa), temperature (50 to 70°C), and mean particle size (0.50 to 1.50 mm). The optimum values of pressure, temperature and mean particle size to achieve optimum responses (galls extraction yield: 6.02%, tannic acid concentration: 6,149.71 mg/g sample; gallic acid concentration: 96.85 mg/g sample) were 28.11 MPa, 50.43°C, and 1.25 mm, respectively. The findings also demonstrated that the extracts possess antioxidant activity and cell proliferation and migration abilities.
