Blueberries are fruits known for their high level of anthocyanins, which have high nutritional value and several biological properties. However, the chemical instability of anthocyanins is one of the major limitations of their application. The stability of blueberry anthocyanin extracts (BAEs) encapsulated in a ferritin nanocarrier was investigated in this study for several influencing parameters, including pH, temperature, UV-visible light, redox agents, and various metal ions. The outcomes supported the positive role of protein nanoparticles in enhancing the stability of blueberry anthocyanins by demonstrating that the stability of encapsulated BAE nanoparticles with ferritin carriers was significantly higher than that of free BAEs and a mixture of BAEs and ferritin carriers. This study provides an alternative approach for enhancing blueberry anthocyanin stability using ferritin nanocarrier encapsulation.
蓝莓是一种以高含量的花色苷而闻名的水果，花色苷具有很高的营养价值和多种生物特性。然而，花色苷的化学不稳定性是限制其应用的主要因素之一。本研究考察了蓝莓花色苷提取物（BAEs）在铁蛋白纳米载体中的稳定性，研究了几个影响因素，包括 pH 值、温度、紫外可见光、氧化还原试剂和各种金属离子。结果表明，蛋白质纳米粒子在提高蓝莓花色苷稳定性方面发挥了积极作用，证明了铁蛋白载体包封的 BAEs 纳米颗粒的稳定性明显高于游离 BAEs 和 BAEs 与铁蛋白载体混合物的稳定性。该研究为使用铁蛋白纳米载体包封来提高蓝莓花色苷稳定性提供了一种替代方法。
