忧遁草多糖乳液体外消化特性研究

Study on the in Vitro Digestion Characteristics of Polysaccharides Emulsion from Clinacanthus nutans

  • 摘要: 本实验主要考察忧遁草多糖(Clinacanthus nutans polysaccharide,CNP-P2)作为乳化剂稳定乳液的体外消化特性及其负载虾青素(Astaxanthin,AST)递送体系的能力,旨在为C. nutans加工及其在食品中的应用提供理论与方法指导。本研究以阿拉伯胶(Gum Arabic,GA)为对照,通过液滴大小、Zeta电位、微观结构和FFA释放量来评价CNP-P2乳液体外胃肠道消化行为。结果表明,CNP-P2乳液在模拟胃消化中能保持稳定。CNP-P2乳液的游离脂肪酸(Free Fatty Acid,FFA)释放量为32.41%,GA乳液的最终释放量为31.68%。构建负载AST的CNP-P2乳液递送体系,评价其稳定AST的能力和生物可及性。CNP-P2乳液能较好地保留紫外光照射下AST的含量,胃肠消化时FAA释放量为27.22%,生物可及性为44.43%±1.63%,CNP-P2乳液能够显著提高大豆油(2.5%)中AST的生物可及性(P<0.05)。基于以上结果,有效延缓脂质消化的前提下,利用CNP-P2制备的慢消化乳液能有效递送AST。

     

    Abstract: This study aimed to investigate in vitro digestion characteristics of emulsion stabilized use Clinacanthus nutans polysaccharide (CNP-P2) as an emulsifier and its ability to support the astaxanthin (AST) delivery system, providing theoretical and methodological guidance for the processing of C. nutans and its application in food. The gastrointestinal behavior of CNP-P2 emulsion was evaluated by droplet size, Zeta potential, microstructure, and FFA release in a controlled experiment using Gum acacia (GA). The results showed that CNP-P2 emulsion could remain stable in the stomach stage with a free fatty acid (FAA) release of 32.41%, and the final release of GA emulsion was 31.68%. A CNP-P2 emulsion delivery system loaded with AST was constructed to evaluate its ability and bioaccessibility for astaxanthin (AST) stabilization. CNP-P2 emulsion could retain AST content well under ultraviolet irradiation, with an FAA release of 27.22% during gastrointestinal digestion and a bioaccessibility of 44.43%±1.63%. CNP-P2 emulsion could significantly improve the bioaccessibility of AST in soybean oil (2.5%) (P<0.05). Based on the above results, under the premise of effectively delaying lipid digestion, the slow digestion emulsion prepared by CNP-P2 can effectively deliver astaxanthin.
