Oleosin

[2] Models show oleosins having a hairpin-like hydrophobic shape that is inserted inside the triacylglyceride (TAG), while the hydrophilic parts are left outside oil bodies.

Instead of a stabilizer of oil bodies, oleosins are believed to be involved in water-uptaking of pollen on stigma.

Allergic reactions to oleosins from hazelnut, peanut and sesame oils have been confirmed, ranging from contact dermatitis to anaphylactic shock.

In contrast, commercial-grade sesame oil is typically an unrefined product with a measurably higher protein content.

[6] In addition to being a food ingredient, sesame oil can be present in drug products, dietary supplements and topically applied cosmetics.
