Perilla oil makes a specific harmful chemical called HHE and ethyl furan when heated, and peanut oil makes more of another chemical called pentyl furan — because each oil has different fats.
Scientific Claim
Perilla oil, with high linolenic acid content, uniquely produces 4-hydroxy-2-hexenal and ethyl furan during thermal oxidation, while peanut oil, rich in linoleic acid, produces the highest levels of pentyl furan.
Original Statement
“4-Hydroxy-2-hexenal (HHE) and ethyl furan were only detected in PAO with a high content of linolenic acid, while the greatest level of pentyl furan was detected in PO with abundant linoleic acid.”

Assessment Explanation
The claim reflects exact observations from the abstract without implying causation or health risk. Language is descriptive and matches the study’s in vitro design.
More Accurate Statement
“Perilla oil with high linolenic acid content is associated with the unique formation of 4-hydroxy-2-hexenal and ethyl furan during thermal oxidation, while peanut oil with abundant linoleic acid is associated with the highest levels of pentyl furan.”

Comparison of Furans Formation and Volatile Aldehydes Profiles of Four Different Vegetable Oils During Thermal Oxidation.
The study heated different oils and found that perilla oil (high in one type of fat) made two specific chemicals, while peanut oil (high in another fat) made a different chemical—exactly what the claim said.
