DefinitionThis section has been translated automatically.
The walnut is a tree of the walnut family, which grows up to 25 m high and is found mainly in south-eastern Europe, West and Central Asia, northern India and China.
Their fruits, the actual walnuts, belong to the nuts and like the hazelnut and the pecan nut to the nuts.
The hard shell encloses two irregularly shaped nut halves, which are protected by a small skin. These contain antioxidants and prevent rancidity. The discoloration of the skin when handling the green nut shells is caused by the phylloquinone juglon.

Sensitizations against walnut are rather rare. Like the hazelnut, it used to be considered a potent food allergen, to which patients with birch pollen - pollinosis (see below tree pollen) are particularly sensitive. Since no Bet-v-1-like allergens are found in the walnut, this is not true.
