Proteins and peptides: proteomics approaches for food authentication and allergen profiling

Food authentication and food allergy profiling are relevant topics that must be carefully considered by authorities, food production and manufacturing industries, and customers. Precise, sensitive, and efficient detection procedures are crucial for authenticating food and identifying allergens. In this paper, we present a current review of advanced proteomic approaches for food authentication and allergen profiling. We discuss three proteomics strategies, namely, discovery proteomics, targeted proteomics, and proteomics-based systems biology, used to authenticate food and profile allergens. This review includes a selection of the most representative papers published in this field in the last few years. Furthermore, we discuss future directions and potential opportunities in this field.
