Sesame (Sesamum indicum L.) is a plant native to tropical Africa that is universally cultivated for its seeds. These are used in various food products, namely in oriental cuisine, but their use in Europe has been increasing significantly.

Sesame seeds contain 50 to 60% oil and 19 to 25% protein, with seven allergenic proteins identified in sesame seeds. (1)

Sesame allergy has been increasing globally over the last two decades and is usually lifelong. Its symptoms can be very variable, from mild reactions, such as hives, to more severe ones, such as anaphylaxis. (1, 2)
After the diagnosis of sesame allergy, the treatment involves eliminating it from the diet.

European legislation requires the prominent identification of sesame seeds and sesame seed-based products on food labeling (3). However, in other countries outside the European Union sesame is not always identified as an allergen, so extra attention is needed when reading the label. See in the table below which foods can contain sesame seeds.

People who are allergic to sesame seeds may also react to peanuts and nuts. This phenomenon is called cross-reaction. It occurs when the body mistakenly identifies a similar protein as the protein of the allergen to which it is sensitized, causing the same type of allergic reaction. (1)

How to identify sesame on the label:
Sesame, sesame seeds, sesame oil.

Unlike other vegetable oils, sesame oil is not usually refined, so it contains a high content of allergenic proteins. Thermal processing of seeds such as cooking or toasting also increases their allergenic capacity. (1)

Fidu does not process sesame seeds or handle foods containing them on its premises, so its products do not contain sesame seeds or traces. Therefore, all Fidu products are safe for those who are allergic or sensitive to sesame seeds.
