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.

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 shows that roasting sesame seeds helps get more oil, but not as much as the claim says. It found a max of 62.6% oil, not 86.6%.

Gold Standard Evidence Needed

According to GRADE and EBM methodology, here is what ideal scientific evidence would look like to definitively prove or disprove this specific claim, ordered from strongest to weakest evidence.
