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.
生物活性化合物的有效传递最近受到了关注。在这项研究中，通过电泳、邻苯二甲醛法和吸光度变化，证实了通过美拉德反应合成的与 BSA 和褐藻胶结合的缀合物。在 60°C 和 79%相对湿度下，4 天内，2 摩尔褐藻胶与 1 摩尔 BSA 糖化。在 4°C 和 25°C 下储存时，涂有 B-F 缀合物的液滴保持稳定，仅在 55°C 下略有增加，然而，涂有完整 BSA 和 B/F 混合物的液滴显著增加。L/Z 在 4°C、25°C 和 55°C 下的降解率分别约为 82%、79%和 36%，与乳化剂的类型无关。尽管缀合物不能防止叶黄素和玉米黄质在储存过程中的降解，但它们提高了乳液的稳定性，与完整的 BSA 和 B/F 混合物相比，生物利用度分别提高了 4.20 倍和 1.32 倍。
