Hexane (C6H14) is a hydrocarbon extracted from crude oil. In fact, hexane is similar to the gasoline we put in our cars; it's just a slightly lighter molecule made of six carbon chains-compared to octane's eight. In its pure form, hexane is a colorless solvent that evaporates easily and dissolves only slightly in water. It's incredibly volatile and highly flammable, and its vapors can be explosive.
CAS 110-54-3 Hexane is widely used because it efficiently extracts oils from crops and seeds like soybeans, corn, sunflower and rapeseed. These oils are refined with the aim of removing the hexane, then sold in supermarkets and used in everyday food items
Why is hexane (CAS 110-54-3) allowed in food?
n-Hexane is allowed as a processing aid in food production (primarily for extracting vegetable oils).
Efficiency & Economics: N-Hexane Chemical is highly efficient at dissolving oils, offering high yields with minimal energy use.
Volatility: n-hexane c6h14 is readily removed from the final product (crude oil) via distillation under vacuum and heat.
Regulated Residues: Food safety agencies (e.g., FDA/EFSA) set very low limits for hexane residues in the final oil. At these levels, it poses no health risk.
Lack of Practical Alternatives: A similarly efficient, cost-effective organic solvent has not been widely adopted for large-scale production.
What precautions should be taken when using hexane in food?
- Residue limits: Controllable process for legal hexane limits (e.g. <1-10 ppm in oil).
- GMP: "Food grade" hexane only, free from benzene.
- Complete removal: Use desolventizers and vacuum distillation.
- Worker safety: Protect from hexane via proper ventilation, PPE, monitoring.
- Test final product: Verify hexane levels in edible oil.
