Protiens in apples can cause mouth allergy

mEver wondered why eating fresh apples sometimes causes your mouth to be itchy? These symptoms are most likely due to something known as a mouth allergy, caused by apples. The mouth allergy is a form of food allergy that is caused by a person having an allergy to a particular pollen. The pollen, in this case birch pollen, has similar proteins.
When a fresh apple is eaten, a person may experience itching, burning, or stinging sensations of the mouth, throat and tongue. The symptoms generally last only a few seconds or minutes, as the proteins that cause the symptoms are broken down quickly by saliva. Since cooking, baking or processing the food (as is the case with applesauce) breaks down these proteins as well, a person with OAS to a fresh apple can eat applesauce without symptoms.
