Sucrose esters (SE) have been investigated as structuring agents in oleogels. Due to the low structuration power of SE as single agent, this component has recently been explored in combination with other oleogelators to form multicomponent systems. This study aimed to evaluate binary blends of SEs with different hydrophilic-lipophilic balances (HLBs) with lecithin (LE), monoglycerides (MGs) and hard-fat (HF), according to their physical properties. The following SEs, SP10-HLB2, SP30-HLB6, SP50-HLB11, and SP70-HLB15, were structured using three different routes: "traditional", "ethanol" and "foam-template". All binary blends were made using a 10% oleogelator in 1:1 proportion for binary mixtures; they were then evaluated for their microstructure, melting behavior, mechanical properties, polymorphism and oil-binding capacity. SP10 and SP30 did not form well-structure and self-standing oleogels in any combination. Although SP50 showed some potential blends with HF and MG, their combination with SP70 led to even more well-structured oleogels, with a higher hardness (~0.8 N) and viscoelasticity (160 kPa), and 100% oil-binding capacity. This positive result might be attributed to the reinforcement of the H-bond between the foam and the oil by MG and HF.
蔗糖酯（SE）已被研究作为油凝胶中的结构化剂。由于SE作为单一剂的结构化能力较低，最近该成分已与其他油凝胶剂结合探索以形成多组分体系。本研究旨在根据其物理性质评估具有不同亲水亲油平衡（HLB）的SE与卵磷脂（LE）、甘油单酯（MGs）和硬脂（HF）的二元共混物。使用三种不同途径构建了以下SE：SP10-HLB2、SP30-HLB6、SP50-HLB11和SP70-HLB15：“传统”、“乙醇”和“泡沫模板”。所有二元共混物均以1:1的比例在10%的油凝胶剂中制成二元混合物；然后对它们的微观结构、熔化行为、机械性能、多晶型和油结合能力进行评估。SP10和SP30以任何组合都不能形成结构良好且自立的油凝胶。尽管SP50与HF和MG显示出一些潜在的共混物，但它们与SP70的组合导致形成结构更良好的油凝胶，具有更高的硬度（约0.8 N）和粘弹性（160 kPa），以及100%的油结合能力。这一积极结果可能归因于MG和HF对泡沫与油之间氢键的增强作用。
