Allergenicity considerations should be always addressed in a dossier, although the extent of allergenicity data required for a Novel Food dossier submission depends on the nature of the food and its production process. Allergenicity data is particularly critical for novel proteins, traditional proteins generated by novel production methods or from novel sources.
At a minimum, literature searches should be provided to supply information about the potential risks and the protein should be clearly identified and compared to determine homology with known allergens. This comparison involves analysing the amino acid sequence against those of known allergens in established databases. In cases of high cross-allergenicity risks, in-vitro and even clinical data might have to be provided.
