摘要:

针对花青素等活性物在使用中易失活的应用瓶颈,该研究构建了二氧化硅纳米颗粒(SiO2 NPs)与司盘80 (Span 80)借助静电吸附来共同稳定Pickering乳液体系以提高花青素稳定性。共稳定型Pickering乳液的花青素包封率为98.5%。在紫外光照射实验中,共稳定型Pickering乳液中花青素保留率分别为SiO2乳液组、Span 80乳液组及花青素水溶液的1.4倍、3.3倍及36.9倍。该共稳定型Pickering乳液体系展现出良好的稳定性,37 ℃储存21天后粒径仅增大38.2 μm,远小于SiO2组乳液(94.6 μm)和Span 80组乳液(263.3 μm)的变化量。实验结果表明,SiO2 NPs和Span 80协同作用提高了Pickering乳液的稳定性,同时增强了花青素的光稳定性。为日用化学工业中活性物稳定性保护提供了新平台。

Abstract:

To address the practical challenge of activity loss in anthocyanins and other bioactive compounds in application, a Pickering emulsion system co-stabilized by silica nanoparticles (SiO2 NPs) and Span 80 via electrostatic adsorption is developed to enhance anthocyanin stability. The co-stabilized Pickering emulsion achieves an anthocyanin encapsulation efficiency of 98.5%. Under ultraviolet irradiation, the anthocyanin retention rate in the co-stabilized emulsion is 1.4 times, 3.3 times, and 36.9 times higher than that in the SiO2 NP-stabilized Pickering emulsion, Span 80-stabilized emulsion, and free anthocyanin solution, respectively. The co-stabilized Pickering emulsion also demonstrates excellent storage stability, with a minimal increase in droplet size of only 38.2 μm after 21 days of storage at 37 ℃, significantly lower than the increases of the SiO2 NP-stabilized Pickering emulsion (94.6 μm) and the Span 80-stabilized emulsion (263.3 μm). These results indicate that the synergistic interaction between SiO2 NPs and Span 80 not only improves the stability of the Pickering emulsion but also enhances the photostability of anthocyanins. This study provides a promising platform for improving the stability of active ingredients in the daily chemical industry.
