According to the American Academy of Allergy, Asthma & Immunology, five major allergens have been isolated from grapes, and a profilin protein is one of them. While not the most common grape allergen, profilin in grapes can trigger allergic reactions, particularly in people with pre-existing pollen allergies.

According to research, strawberries indeed contain profilin, a protein involved in cell structure that can act as a pan-allergen. Its presence in strawberries can be a factor for individuals who experience allergic reactions, especially those with pre-existing pollen allergies.

In a 2022 study, researchers identified 47 chitinase genes in the genome of domesticated apple (Malus domestica), proving that apples have chitinase. These enzymes are vital components of the fruit's pathogenesis-related (PR) protein family, which serves as a frontline defense against threats like fungal pathogens.

While potatoes are a global dietary staple, containing moderate amounts of protein and fiber, they also contain a family of small proteins known as LTPs. A study published in March 2023 identified 39 members of the lipid transfer protein (LTP) family in the potato plant, revealing their role in plant stress responses, but the risk for human allergy depends on individual sensitization and which specific LTPs are consumed.
