在这项研究中,合成了荞麦花多糖结合物(BFPCs),并对其乳化性能进行了评估。通过粒度分析评估BFPC稳定的乳液的稳定性,zeta电位测量,微观观察,和流变测试。阿拉伯树胶作为对照,比较BFPC在不同储存条件下的乳化功效,包括接触金属离子,pH值变化,和不同的热处理温度。结果表明,BFPC显着降低了界面张力(16.2mN/m),并有效地稳定了浓度为1.0wt%的含60wt%中链甘油三酸酯的乳液。在20天的储存期内,BFPC乳液表现出强大的耐热性(60-90°C),酸性条件(pH2.0-9.0),和离子浓度(Na+,Ca2+)。此外,在高油相乳液中,BFPC将姜黄素的生物利用度提高到27.05%,明显高于未乳化的7.10%,强调其在营养输送应用中的潜力。实际应用:由于其优异的电阻,不同条件下的长期乳化稳定性,以及它在姜黄素包埋中的良好效果,BFPC具有广阔的前景,可以在各种条件下广泛用于食品工业。
In this study, buckwheat flower polysaccharide conjugates (BFPCs) were synthesized and evaluated for their emulsification properties. The stability of BFPC-stabilized emulsions was assessed through particle size analysis, zeta potential measurements, microscopic observations, and rheological tests. Gum Arabic served as a control to compare BFPC\'s emulsifying efficacy across varying storage conditions, including exposure to metal ions, pH variations, and different heat treatment temperatures. Results showed that BFPC significantly lowered interfacial tension (16.2 mN/m) and effectively stabilized emulsions containing 60 wt% medium-chain triglycerides at a concentration of 1.0 wt%. Over a 20-day storage period, BFPC emulsions demonstrated robust resistance to heat (60-90°C), acidic conditions (pH 2.0-9.0), and ion concentrations (Na+, Ca2+). Moreover, in a high oil phase emulsion, BFPC enhanced the bioavailability of curcumin to 27.05%, markedly higher than the 7.10% observed without emulsification, underscoring its potential in nutrient delivery applications. PRACTICAL APPLICATION: Due to its excellent resistance, long-time emulsifying stability under different conditions, and its good effect in curcumin embedding, BFPC has a broad prospect and can be widely used under various conditions in food industry.
