WebAsad Malook Most methods measure either transmittance or reflectance, normalize the measured spectra and convert it to absorbance by -log 10 (T/T 0) or -log 10 (R/R 0). WebOvotransferrin-derived peptides showed synergistic effects with vitamin C, epigallocatechin gallate (EGCG), and caffeic acid, but not quercetin in our previous report. In this study, we further investigated the interactions between ovotransferrin-derived peptides and teas, based on the oxygen radical absorbance capacity (ORAC) assay.
