Effects of Seed Roasting Temperature on Sesame Oil Fatty Acid Composition, Lignan, Sterol and Tocopherol Contents, Oxidative Stability and Antioxidant Potential for Food Applications

Cross-Sectional Study

In Vitro

2022 Jul 14

The study looks at what happens when sesame seeds are roasted at high temperatures, and it finds that harmful fats start to form when seeds are roasted too hot, which matches what the claim says.

Similar Assertions

Roasting sesame seeds at the right temperature helps get more oil out of them — especially when heated to 250°C — because the heat breaks open the tiny cells inside the seeds where the oil is stored.
