Figure 4

Effects of antioxidant concentration on the observed pseudo-first-order rate constants k obs of β-carotene bleaching with linoleic acid peroxyl radical at 50°C. Values of k obs were obtained by monitoring the absorbance of β-carotene aqueous solution (8.2 μM) at 460 nm. The dotted horizontal line indicates the value of k obs in the absence of antioxidants as a control
