Modulation of structure, functionality, allergenicity and in vitro digestibility of ovalbumin through cold plasma-induced conjugation with rosemary-derived phenolic acids. (PubMed, Food Chem ) - Sep 18, 2026 - "Cold plasma (CP)-induced covalent conjugation between ovalbumin (OVA) and three rosemary-derived phenolic acids (RDPAs), namely chlorogenic acid (CGA), caffeic acid (CA), and rosmarinic acid (RA), was investigated to elucidate how phenolic acid molecular architecture governs the structure, functionality, in vitro digestibility, and allergenicity of OVA...Furthermore, covalent grafting of RDPAs, particularly RA, effectively promoted gastrointestinal digestive trajectories of OVA, and the resulting digests substantially reduced IgE-binding affinity. These findings suggest that CP-mediated covalent RDPAs conjugation is a mild and effective, structure-guided approach that holds potential for the development of egg protein ingredients with enhanced functionality and reduced allergenicity."
