Corn Allergy

Key Allergens

The terms maize and corn are often used interchangeably- maize is the name of the plant that grows corn, which is the product we eat.

There are 5 key allergens associated with corn, 3 of them are classified as airway allergens and 2 food allergens.

Zea m 8 is a chitinase protein. This is a plant derived enzyme made by plants naturally to act as a defence against fungal attacks

Zea m 14 is a lipid transfer protein (LTP).


Corn allergy has been linked to Latex Food Syndrome, which is caused by the body confusing the proteins it encounters in food to that of latex proteins to which it is already sensitised.

LTP's are a group of proteins which can cause more serious allergic reactions in patients, you may suffer from LTP Syndrome if you suffer IgE type allergy symptoms to foods mentioned in the cross reactivity section below.

Cross Reactivity

Those with a sensitivity to chitinase may have linked allergies to foods which contain high levels of chitinase, like avocado, banana, chestnuts, maize, kiwi, papaya, pomegranate and tomatoes.

Foods linked to LTP Syndrome are hazelnuts, almonds, walnuts, apples, dried fruit, lettuce and tomatoes. Symptoms are more intense if food is dried or concentrated.
