Types of Allergens

Allergens are classified into various types including pollen, dust mites, food, fungi, and insects. Based on the systematic classification by the WHO/IUIS Allergen Nomenclature Sub-Committee, their molecular characteristics and clinical significance have been elucidated. In Japan, there are labeling requirements for 8 specified allergenic ingredients, with full implementation of walnut labeling beginning in April 2025. Pollen allergens are categorized into three major groups: trees, grasses, and weeds, while dust mite allergens include major groups such as Der p and Der f.
