Abstract	Solvent extraction is a widely used technology in edible oil industries for efficient recovery of oil from oil-bearing materials such as soybean, sunflower, rapeseed, groundnut, and cottonseed. The process primarily relies on food-grade hexane, which poses environmental, safety, and economic challenges due to its volatility and flammability. Solvent recovery thus becomes a critical step in minimizing losses, ensuring economic viability, and meeting regulatory standards. This paper reviews existing and emerging solvent recovery methods, evaluates their performance in terms of recovery efficiency, energy consumption, safety, and cost-effectiveness, and proposes future directions for sustainable practices in edible oil industries.
