(a) Schematic illustration of the proposed interactions between the functional moieties of phenolics and different amino acid of proteins. Asn = asparagine, Val = valine, Asp = aspartic acid. (b) Stability of protein–polyphenol capsules (LYZ, IgG, Hgb, GOx, and CYC) after 1 h of incubation with 100 mM of urea, Tween 20, or NaCl, corresponding to the dominant interactions between the different proteins and TA.
