Figure 2

Fluorescence emission spectra of Heberprot-P75®, Easyef®, and methyl-parabenzoic acid. (A) Pre-scan of full-range emission fluorescence spectrum 190–900 nm. (B) Wavelength maximum fluorescence (WMF) of Trp spectrum (Ex = 295 nm, Em = 305–400 nm). The inset graph shows the change in the fluorescence intensity depending on ozonated sunflower oil (OSO) treatment. In order to compare fluorophore properties, collisional quenching of Trp was performed by adding the OSO into Heberprot-P75® and Easyef®.
