Influence of Rosemary Extract Addition in Different Phases on the Oxidation of Lutein and WPI in WPI-Stabilized Lutein Emulsions

Figure 3

Effect of the rosemary extract (RE) addition in different phases (oil and water phase) on the droplet size (a), zeta-potential (b), and instability index (c) of WPI-stabilized lutein emulsion before storage (0 days) and after storage (7 days) at 55°C. Data points represent means (n = 3) ± standard deviations.
