The effective delivery of bioactive compounds has recently been receiving attention. In this study, a conjugate with BSA and fucoidan synthesized via the Maillard reaction was confirmed through electrophoresis, the o-phthalaldehyde assay, and through changes in absorbance. Two moles of fucoidan were glycated with one mole of BSA at 60 °C and 79% relative humidity for 4 days. The droplet coated with B-F conjugate remained stable during storage at 4 and 25 °C and slightly increased only at 55 °C however, the droplet coated with intact BSA and B/F mixture significantly increased. L/Z were degraded about 82, 79, and 36% for 4, 25, and 55 °C, respectively, regardless of the type of emulsifier. Although the conjugates could not prevent the degradation of lutein and zeaxanthin during storage, they improved the stability of the emulsion and showed 4.20-fold and 1.32-fold higher bioaccessibility than intact BSA and B/F mixtures, respectively.
