Description
3 studies reviewed
In plain English

Hexane is used to extract oils from plants in food manufacturing and is not required to appear on ingredient labels because regulators classify it as a processing aid.

See the scientific wording

Hexane, a hazardous air pollutant, is used in the industrial extraction of plant oils and is not required to be listed on food labels due to its classification as a processing aid.

Why this might work

Hexane remains in plant oils after extraction because it does not fully evaporate during processing, and this residue is not removed before the oil is sold for consumption.

What the research says

3 studies

  1. Study: Supercritical CO2 Extraction vs. Hexane Extraction and Cold Pressing: Comparative Analysis of Seed Oils from Six Plant Species

    The study shows that hexane is one of the methods used to pull oil out of seeds like pumpkin and flax, which means it’s really used in making cooking oils — just like the claim says. It doesn’t talk about labels, but it confirms hexane is used in food factories.

  2. Study: Technical Report on the need for re‐evaluation of the safety of hexane used as an extraction solvent in the production of foodstuffs and food ingredients

    Hexane is used to pull oil out of plants for food, and regulators don’t make companies list it on ingredients because they call it a 'processing aid.' This study says we need to check if hexane is really safe, since old safety rules might be outdated and kids might be exposed to more than we thought.

  3. Study: Response Surface Optimization of Hexane Extraction and Chemical Characterization of Oil From Locusta migratoria

    This study shows that hexane is used to pull oil out of insects for food, which proves hexane is really used in making food oils — just like the claim says. It doesn’t talk about labels, but it confirms the main part of the story.
