Scientists are in the process of developing a hypo-allergenic apple that causes no allergic reaction.

Dr. Alessandro Botton, a plant physiologist at the Department of Agronomy, Food, Natural Resources, Animals and Environment in the University of Padua, and his team are working to find alternative hypo-allergenic proteins that exist naturally in other plants and swap them for the irritation-causing proteins in apples.
Botton said that they cannot know what will happen when they silence a biological gene.
However, Botton said that by using other plant proteins, the structure of the apple would likely not be significantly changed.
Botton said that genetically modified apples provide a faster option for developing hypo-allergenic varieties compared to the traditional means.
