Green solvents and technologies for oil extraction from
The conventional technology used for oil extraction from oilseeds is by solvent extraction. In solvent extraction, n -hexane is used as a solvent for its attributes such as simple recovery, non-polar nature, low latent heat of vaporization (330 kJ/kg) and high selectivity to solvents. However, usage of hexane as a solvent has lead to several
The highest average oil yield of 82.7% (±3.03) was obtained from Chemical Extraction Method using n-hexane as solvent, Mechanical Extraction Method gave 72.9% (± 1.49) while the lowest oil yield
The effect of alternative solvents to n-hexane on the green
To explore these possibilities, this study performed comprehensive comparative analyses of lipid profiles and phytosterol compositions in coconut oils obtained by extraction with n-hexane, absolute ethyl alcohol, deep eutectic solvent/n-hexane, dimethyl carbonate (DME) and cyclopentyl methyl ether (CPME) using a foodomics approach.
Therefore, while there is SFE extraction with supercritical CO 2 as solvent that we can do without using chemical solvents; instead of choosing the extraction techniques that we are using chemical solvents such as hexane (soxhlet) or that give low yield results (cold press), SFE has been determined as the appropriate method for coconut oil
A comprehensive review on the techniques for coconut oil
This method however requires a longer time to extract coconut oil as it needs to settle for days . An automated coconut oil extraction machine applying this method of extraction is designed by Fabian in year 2018. Without using the automated machine, the maximum percent oil recovery of VCO is at 88.35% and a yield of 30–31%.
The Refined, Bleached and Deodorized (RBD) Coconut Oil (CO) and RBD Palm Oil (PO) are heavily consumed as cooking oils by Asians. Recently, Virgin Coconut Oil (VCO) and Palm-pressed Mesocarp Oil (PPMO) emerged into the market as functional oils. A number of studies were conducted to extract these edible oils by using different methods
Chemical composition and antioxidant activity of oil obtained
Coconut meal is a residue obtained after the extraction of coconut milk from the grated fresh kernel. Our previous stud-ies revealed that hydrolysis of coconut meal using subcritical water is an eective method for producing manno-oligosac-charides [7, 8]. However, since the meal still contains around 22% of oil [9, 10], extraction of the oil
Coconut is extracted by dry and wet process. In spite of various techniques, wet processing is less viable than dry processing due to a 10-15% lower yield [4]. Conventional coconut oil uses hexane as solvent to extract up to 10% more oil from just using rotary mills and expellers. Many health
Optimization of oil extraction from coconut using response
In this study, coconut oil was extracted from coconut fruits using hexane as solvent and the objective of this work was to determine the effect of roasting temperature and time on the yield and quality of coconut oil using RSM. This was targeted towards obtaining optimal benefits in terms of yields and quality of the refined coconut oil.
Thermodynamic and economic feasibility of coconut oil extraction with supercritical CO 2 was evaluated. • Empirical state equations surrounding critical CO 2 point were fitted. • A rigorous mathematical model for extraction kinetics was built. • Mass transfer and equilibrium properties of coconut oil were empirically evaluated. •
