Food allergy is first detected in the mouth. As offending, allergenic molecules pass through the mouth, surface antibodies, which are attached to mast cells, react with the food antigens. This triggers swelling and inflammation of the lips, mouth surfaces, and throat. The reaction may be minute and limited to swelling of a small area on the tongue, or it may cause a life-threatening swelling of the whole tongue and throat.
Continuous allergic inflammation in the mouth and nose may obliterate pleasant eating sensations and is associated with disordered food selection. The complete sensation of taste is dependent on proper smell, obliterated by a stuffy, swollen nose. People with blunted taste often prefer heavy doses of the primary tastes, bitter, salt, and sugar.

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.

Mouth allergy is suspected in canker sores
What causes canker sores (aphthous ulcers)? What are the risk factors for triggering outbreaks of these mouth ulcers? Canker sores are a type of mouth ulcer. In fact, they are the most common type of recurring mouth ulceration. The cause of canker sores is not well understood. Their formation, however, is thought to be related to an abnormal response by the sufferer's immune system.
Allergies to foods and other substances have been postulated as being triggers for canker sore breakouts. Any substance that comes into contact with the person's oral tissues must be considered to be a potential causative agent. If an mouth allergy is suspected the individual might choose to maintain a diary so to help them (and their dentist) identify the most likely candidates associated with the causation of their sores. In some cases allergy testing might be considered.

Mouth allergy symptoms
Oral Allergy Syndrome i.e. mouth allergy is most commonly associated with allergy to birch pollen, but can occur with other pollens such as ragweed, mugwort sage, plantain, and grasses. Fruits and nuts are the foods most commonly implicated, but other foods can cause the symptoms as well.
Most authorities say it is not necessary to avoid all foods associated with a given pollen allergy. They recommend avoiding only the foods which cause symptoms of mouth allergy. Often it is the raw food that causes the mouth allergy symptoms, and many people find they can tolerate these foods without symptoms when the foods are well cooked.
