Mulberry are fruit in the Moraceae
family of plants. Other plants in this family include fig, breadfruit and jackfruit.
The main allergy associated with black mulberries is Mor n 3, this is a lipid transfer protein (LTP)
. LTPs are resistant to heat and are found in many types of plants. Patients suffering from a more severe allergy to cooked fruit may be sensitised to this group of proteins.
The white mulberry plant has an allergen, Mor a 2 which is associated with pollen allergies and asthma linked reactions.
Mulberry silk is a material made from the secretions of silkworms which have fed exclusively on mulberry trees. Silk allergy is associated with allergic contact dermatits, but is not related to the food allergens in mulberries.
You may be suffering from LTP Syndrome if you have reactions to various fruits, vegetables and nuts and your reactions continue to be severe after you have discarded the peel and have cooked the food.
Common foods involved in LTP allergy include kiwi, strawberries, sunflower seeds, walnut, apple, mulberry, banana, pea, apricot, cherry, plum, almond, peach pomegranate, raspberry, tomato, grape, celery, peanut, asparagus, cabbage, broccoli, chestnut, lemon, tangerine, orange, hazelnut, lettuce, lentils, lupin, green bean, pear, mustard, wheat and maize.
