Hazelnut (Corylus avellana) belongs to one of the most potent elicitors of food allergy. Patients sensitized to the hexameric non-glycosylated storage protein and minor allergen, Cor a 9, are likely to react to raw and roasted hazelnut. The 11S legumin-like seed storage globulin, also known as corylin, is associated with severe systemic reactions.
The family of 11 S-globulins represents precursor proteins which are cleaved into two chains, originally linked together by a disulphide bond. The true food storage protein or pollen-independent hazelnut allergen indicates a primary hazelnut allergy as it does not show cross-reactivity to Bet v 1 as for e.g. Cor a 1.
The non-specific lipid transfer protein (nsLTP), Tri a 14, is a major allergen in one of the most common forms of occupational asthma: baker’s asthma. The disease is mainly caused by wheat flour inhalation. LTPs constitute a relevant family of plant food panallergens. These allergens show high resistance to heat treatment as well as proteolytic attack and are capable of inducing severe symptoms.
