Pickering stabilizers with additional antioxidant, photostabilizing, and metal-chelating properties are suitable for structuring multifunctional Pickering emulsion systems. Tannic acid (TA) is a potential material which when adsorbed onto the interface may impart antioxidant, UV-light-shielding, and chelating properties to Pickering stabilizers. Herein, we report a type of TA polyelectrolyte nanoparticles (NPs) fabricated following a complexation between TA and aminated sugar beet pectin (SBP-NH₂). This study is geared toward investigating the performance of TA/SBP-NH₂ NPs in stabilizing Pickering emulsions and protecting β-carotene from degradation. TA/SBP-NH₂ NPs formed under optimum conditions had a mean diameter of 82 nm with a sphere-like shape. Because of their favorable surface wettability (91.2°), TA/SBP-NH₂ NPs promoted formation of the low-, medium-, and high-internal-phase Pickering emulsions (HIPEs) in an oil volume fraction (φ)-dependent manner; the TA/SBP-NH₂ NP-stabilized HIPE demonstrated viscoelastic properties increasing with the increasing concentration (c) of nanoparticles. Due to the excellent storage stability and UV light-absorbing capacity, the photostability of β-carotene was significantly improved by a TA/SBP-NH₂ NP-stabilized HIPE (φ = 0.75; c = 3 mg/mL). Altogether, this study highlights that TA/SBP-NH₂ NPs have potential applications in structuring Pickering emulsions with improved protective effects on loaded lipophilic compounds.

单宁酸胺化甜菜果胶纳米颗粒作为高内相 Pickering 乳液的稳定剂

具有额外抗氧化、光稳定和金属螯合特性的皮克林稳定剂适用于构建多功能皮克林乳液体系。单宁酸 (TA) 是一种潜在的材料，当它吸附在界面上时，可以赋予 Pickering 稳定剂抗氧化、紫外线屏蔽和螯合性能。在此，我们报告了一种 TA 聚电解质纳米粒子 (NPs)，该纳米粒子是在 TA 和氨基甜菜果胶 (SBP-NH ₂ ) 之间络合后制造的。本研究旨在研究 TA/SBP-NH ₂ NPs 在稳定 Pickering 乳液和保护 β-胡萝卜素免于降解方面的性能。TA/SBP-NH ₂在最佳条件下形成的纳米颗粒的平均直径为 82 nm，呈球形。由于其良好的表面润湿性 (91.2°)，TA/SBP-NH ₂ NPs 促进了低、中、高内相 Pickering 乳液 (HIPE) 以油体积分数 (φ) 依赖的方式形成; TA/SBP-NH ₂ NP-稳定的HIPE表现出随着纳米粒子浓度( c )的增加而增加的粘弹性。由于优异的储存稳定性和紫外光吸收能力，TA/SBP-NH ₂ NP 稳定的 HIPE (φ = 0.75; c = 3 mg/mL) 显着提高了β-胡萝卜素的光稳定性。总之，这项研究强调了 TA/SBP-NH ₂纳米粒子在构建皮克林乳液方面具有潜在的应用，对负载的亲脂性化合物具有更好的保护作用。
