Effect of pre-harvest and post-harvest conditions on fruit allergenicity

Authors: Wang, Jin; Vanga, Sai Kranthi; Raghavan, Vijaya
Description: Fruits are an important source of vitamins and antioxidants that can effectively delay aging and contribute to health and well-being of the human population. However, they are growing to be one of the most important elicitors of food allergies around the world. Fruit allergens induce an IgE-mediated (Immunoglobulin E) reaction presenting with a wide range of symptoms, from a localized oral allergy syndrome (OAS) to life-threatening anaphylaxis. But, many studies have shown that different environmental and cultivation conditions like fertilizer application, water stress, and climatic factors can influence the allergen content in fruits during flowering and ripening stages. Further, the variety, harvesting maturity, location within the peel, pulp and seeds of a fruit and storage conditions can also significantly influence their allergenicity potential to inflict on consumers. For example, unripe apples and tomatoes have lower levels of allergens compared to ripened fruits resulting in reduced risk of IgE-mediated reactions. Researchers have also shown that modified atmosphere packaging (MAP) can help reduce allergen content during storage in fruits. Post-harvest processing like peeling is also considered a good method to help reduce the overall allergenicity in few fruits whose skin contains the majority of allergens. This review will discuss the overall influence of both pre-harvest and post-harvest factors on the fruit allergen inflicting potential. We will also discuss the progress regarding the cause, symptoms and diagnostic methods of fruit based allergies.
