Persimmon fruit (also called kaki fruit, persimon and sharon fruit) are in the Ebenaceae
family of plants.
Persimmons are rarely linked to food allergy, to date there are no recorded allergens for persimmon by the World Health Organization (WHO), because there have not been enough study into allergic effects from this food. If you are interested in what is needed by the WHO before they add an allergen to their allergen database you can check that out HERE
The main allergens in persimmons are profilin proteins
, which are panallergens responsible for more severe allergic reactions in seemingly unrelated food.
Persimmon fruit also contain Bet v 1-like proteins
. These proteins are similarly shaped to those ones in birch pollen and can cause oral allergy type symptoms.
Allergy to persimmon can be linked to Celery-Mugwort-Spice Syndrome
, which is a subtype of Pollen Food Allergy Syndrome. This syndrome affects individuals who have become sensitised to pollen and then have oral allergy type symptoms to foods with similarly shaped proteins. The most common form of Pollen Food Allergy Syndrome is the one caused by birch tree pollen. In Celery Mugwort Spice Syndrome the sensitising pollen is mugwort.
You may have Pollen-Food Allergy Syndrome
if you suffer from persimmon allergy with oral allergy symptoms to 3 or more of the foods mentioned in cross reactivity section.
There is a link between persimmon and Latex Food Syndrome
. The plant involved in latex allergy Hevea brasiliensis
, the rubber tree plant, has an allergen called Hev b 8 which is a profilin protein. Those very sensitised to latex may have a contact allergic reaction from other foods or plants containing profilin proteins, there is less evidence of this than sensitisation to other latex linked proteins like hevein and chitinases.
Profilins are also found as food allergens in kiwi, celery, peanut, chilli, watermelon, orange, hazelnut, melon, carrot, strawberry, soya, walnut, lychee, lupin, apple, cherry, almond, peach, pear, mustard, tomato and aubergine.
Other plants containing profilin inhalant allergens are ragweed, wormwood, birch, sunflower, olive, plantain, poplar and oak.
If sensitised to birch tree pollen you may have Pollen Food Allergy Syndrome and may also react to kiwi, pear, peach, plum, nectarine, apricots, apple, tomato, celery, carrot, potato, parsnip, pepper, dill, cumin, peas, coriander, fennel, hazelnut, walnut, almonds, peanuts, lentils and beans.
