Table 1 Comparison of solvent extraction (SE) and aqueous assisted enzymatic (AAE) methods
From: Green solvents and technologies for oil extraction from oilseeds
Parameter | Solvent extraction | Aqueous assisted enzymatic |
|---|---|---|
Nature of the process | Non-environment friendly | Environment friendly |
| Â | Toxic | Non-toxic |
Solvents used | n-Hexane | Green solvents |
Energy efficiency | Energy demanding process due to consumption of oil | Less energy demand process |
Co-product quality | Poor quality due to operational conditions at higher temperature and pressure | Food quality grade due to mild operational conditions |
Degumming | It is essential because of phospholipids | Not required Aqueous medium dissolves the phospholipids |
Others | Ineffective process in removal of toxins and anti-nutritional factors | Highly efficient in removal of toxins and anti-nutritional factors |
Limitations | Limitations are cited above | An additional de-emulsification step is required. High cost for enzyme production |
