Recent advances in green soybean oil extraction: A review
Still, the soybean oil extraction using the same method with ethanol was performed by Rodrigues et al. [103]. The results were almost similar to those obtained in Soxhlet extraction. The PLE using isopropanol and ethanol as a solvent for extracting nut kernel oil was performed by Cornelio-Santiago et al. [104]. This process did not affect the
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.
Simple and effective management methods that can improve
Soybean oil has gained popularity in modern day cooking in Bangladesh. However, as its extraction from soybean seed is not yet possible using traditional methodologies, most of the soybean that the country produces is used predominantly in the feed industries, and any soybean oil in the market is imported.
The main triacylglycerols identified were LLO, LLL, and OOL. The results indicate that soybean oil can be obtained by a new process that uses a safe and renewable solvent, indicating that PLE in an intermittent process can replace conventional extraction without changing the main characteristics of the oil, with good yield using less solvent.
Extraction of vegetable oils from ground seeds by
The influence of particle size and solvent flow rate on the kinetics of oil extraction from soybean (eight fractions from 0.433 to 0.122 mm) was studied using hexane, simulating commercial
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
Studies on alternative solvents for the extraction of oil‐I
There are many studies on soybean oil extraction using green solvents. Gandhi et al. [43] discussed pure and aqueous solvents and azeotropes of n-hexane, ethanol, and n-propanol for extracting
isopropyl alcohol in n-heptane and 100 % n-heptane in a ratio of 25:75 (v/v), was used with a “Restek” Pinnacle DB silica (250 × 4.6 Table 1 Coding of fortified edible oil samples.

- What is the difference between solvent extraction and hexane extraction?
- In comparison, solvent extraction with hexane (the primary solvent used worldwide) will remove all but about ½% of residual oil, uses less horse power, and requires less maintenance. It is relatively efficient and reliable, and this is one reason why solvent extraction is the primary means of separating large tonnages of oil from protein meal.
- How is oil extracted before solvent extraction?
- Before performing solvent extraction the oilseeds are processed (flaked, cracked, ground or pressed) to suit for the enhanced oil recovery by solvent extraction. In SE process, the oilseeds are washed with hexane, thereafter the hexane is separated from oil by evaporation and distillation [ 2 ].
- How n hexane is used in oil extraction?
- 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.
- How can enzyme technology improve oil extraction in oilseed industry?
- Enzyme technology has great potential for oil extraction in oilseed industry. Similarly, green solvents such as terpenes and ionic liquids have tremendous solvent properties that enable to extract the oil in eco-friendly manner.
