Background One of the most basic needs of mankind is an abundant and reliable food supply. In the modern world, one major source of protein and vegetable oil is from oilseeds, particularly the soybean – an abundant resource which is largely processed using solvent extraction, an efficient and reliable means to separate the high-protein meal solids from the high-energy edible oil.
This method is based on the change of oil solubility in ethanol with temperature. Rapeseed oil extraction was carried out by hot pressurized ethanol (subcritical extraction condition). Oil was then recovered by cooling the miscella and demixing of two phases, an oil-rich phase and a solvent-rich phase.

Effect of enzyme treatment at low water content on oil extraction and oil quality. Table 2 summarises the water contents of the flaked rapeseeds before and after addition of 1:1 mixtures of CC and VZ at enzyme dosages of 0.05 –0.5 mL per 100 g rapeseed. The water content of the untreated rapeseeds was significantly lower than that of rape
- How is rapeseed oil extracted?
- The extraction meal is desolventized by desorption and evaporation of hexane through direct and indirect steam injection. The oils are recovered by distillation of miscella, which allows evaporation of volatile solvents by vacuum steam stripping. Fig. 1. Conventional processing procedures for rapeseed oil extraction. Color online.
- Which solvent is used to extract rapeseed oil?
- It was also interesting to observe that p -cymene, d -limonene and isopropanol were the most effective solvents for oil extraction from the original rapeseed, and p -cymene, isopropanol and n -hexane were more selective. Table 1. Extracted rapeseed oil yields with various solvents. ISO 659-1988.
- What are the optimal conditions for oil extraction from rapeseed?
- Above all, the optimal conditions for oil extraction from rapeseed and other seeds have been determined. n -Hexane, which has a relatively low boiling point (69 ¡ãC), is the commonly-used petroleum-based solvent for extraction of vegetable oils.
- Does rapeseed oil extract lipids?
- Experiments were performed on rapeseed oil extraction at laboratory and pilot plant scale for the determination of lipid yields, extraction kinetics, diffusion modeling, and complete lipid composition in term of fatty acids and micronutrients (sterols, tocopherols and tocotrienols).
- Which solvent can replace n -hexane in rapeseed oil extraction?
- In this study, several alternative solvents (ethanol, butanol, isopropanol, d -limonene, ¦Á-pinene and p -cymene) have been used to replace n -hexane as a solvent used in the extraction of oil from rapeseeds.
- How is oil extracted from oilseeds?
- Conventional oil extraction from oilseeds has been performed by hydraulic pressing, expeller pressing and solvent extraction (SE) . Among these methods, solvent extraction has been widely adapted for economical and practical concerns.
