When perilla oil is heated, two chemicals—HHE and ethyl furan—are made together because they both come from the same fat molecule, linolenic acid.

Comparison of Furans Formation and Volatile Aldehydes Profiles of Four Different Vegetable Oils During Thermal Oxidation.

Cross-Sectional Study

In Vitro

2019 Jul

The study found that when perilla oil is heated, it produces two specific chemicals—HHE and ethyl furan—that only come from a fat in the oil called linolenic acid, which means they’re made from the same source, just like two siblings from the same parent.

Similar Assertions

When you heat perilla oil (a type of plant oil) at high temperatures for a long time, it creates two specific chemicals—HHE and ethyl furan—that don’t show up when you heat other oils, because perilla oil has a special fat called linolenic acid.

Two harmful chemicals — HHE and ethyl furan — show up together when you heat oils like perilla oil, and they both come from the same type of fat: linolenic acid.

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.
