The Claim
Supercritical CO2 extraction enables selective fractionation of seed oils into distinct chemical fractions (C-V1, C-V2, C-V3), allowing for targeted recovery of compounds like squalene and γ-tocopherol in later fractions, which is not possible with cold pressing or hexane extraction.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Supercritical CO2 extraction separates seed oils into specific chemical layers, enabling the isolation of squalene and γ-tocopherol in later layers, a result not achieved by cold pressing or hexane extraction.

Supercritical CO2 extraction enables selective fractionation of seed oils into distinct chemical fractions (C-V1, C-V2, C-V3), allowing for targeted recovery of compounds like squalene and γ-tocopherol in later fractions, which is not possible with cold pressing or hexane extraction.
Supercritical CO2 dissolves different oil components at different pressures and temperatures, pulling out lighter compounds first and heavier ones later, so valuable molecules like squalene and γ-tocopherol come out in separate stages.
What the research says
1 studySupercritical CO2 extraction pulls out more of the healthy, valuable compounds from seeds — like squalene — than cold pressing or chemical methods, and leaves behind the less useful parts. This means you can get more of the good stuff in a cleaner, more targeted way.
