A review of defatting processes using sustainable solvents: parallels between seed and fish oil sources

Key Points

• The review aims to explore alternative, sustainable defatting processes for oil extraction from seed and fish sources.
• Reviewed conventional and alternative defatting methods.
• Compared the efficiency and safety of petrochemical solvents versus natural solvents.
• Analyzed the environmental impact of different solvent options.
• Natural deep eutectic solvents show promise for enhancing safety in oil extraction.
• Vegetable oils may provide a more sustainable alternative to hexane for defatting.
• Sustainable methods can potentially reduce the carbon footprint of oil extraction processes.
