Key Allergens

The allergens in rice are called Ory s 1 and Ory s 12.

Ory s 1 is a beta expansin protein. These are found in the cell walls of plants and are a common cause of grass pollen allergies.

Ory s 12 is a profilin protein, most commonly causing allergic reactions in the airway, like hayfever.

Syndromes
