Abstract
Background Hazelnut is one of the most largely consumed tree nuts, which is used in a wide range of processed foods. However, it is classified as a potential allergenic ingredient and, consequently, should be declared in the label of pre-packaged foods (Directive 2007/68/EC), independently of its amounts. To verify the compliance with labelling and to safeguard the health of sensitised individuals, the development of new methodologies for the traceability of allergenic ingredients is essential [1].

Hazelnut is one of the most largely consumed tree nuts, which is used in a wide range of processed foods
In this work, we propose the use of a novel approach based on single-tube nested real-time polymerase chain reaction (PCR) system to trace hazelnut in complex foods [2]
The recently developed system aimed gathering the advantages of nested PCR and real-time PCR technology
Summary
Hazelnut is one of the most largely consumed tree nuts, which is used in a wide range of processed foods. It is classified as a potential allergenic ingredient and, should be declared in the label of pre-packaged foods (Directive 2007/68/EC), independently of its amounts. To verify the compliance with labelling and to safeguard the health of sensitised individuals, the development of new methodologies for the traceability of allergenic ingredients is essential [1]. Highlighting its adequacy for the specific detection and quantification of hazelnut as potential hidden allergens in foods
