Oranges with orange-coloured skin and fleshy fruits. The fruits are often eaten fresh and raw. The juice is also extracted and sold fresh and as a frozen concentrate; it can also be used as a flavoring in jellies, ice cream, etc. The skin is taken advantage of flavoring in cakes, marmalade and other sweets. The orange skin essential oil is used as a food flavoring and in perfumes and medicines.

Orange can trigger food allergy symptoms in sensitised people. Earlier studies have shown that orange is among the top ten food allergens that cause side effects in children. The reported symptoms included nausea, itching, abdominal cramps, abdominal pain, vomiting, diarrhea, oral pruritus, angioedema, dyspnea, bronchospasm, rhinitis, laryngeal edema, urticaria, hypotension, and anaphylaxis.

Oral allergy syndrome (OAS) is a common phenomenon. This latest study has concluded that OSA in children may have different mechanisms than adult OSA, which is almost always accompanied by pollinosis or latex allergy. 

Specific IgE detection in human blood helps to determine the body’s reaction to an allergen such as orange, f33.
