摘要

在本研究中，研究了乳清蛋白浓缩物（WPC）和普鲁兰（PUL）为基础的乳状凝胶包封和递送虾青素（AST）的潜力。研究了PUL浓度对WPC/PUL/AST乳液凝胶微观结构的影响，并通过包封效率、模拟胃肠消化、储存稳定性、硬度和持水量等测试评价了乳液凝胶的性能。在PUL浓度为2.0%时，WPC/PUL/AST乳状凝胶的包封率、胃肠道消化滞留率和生物可达性分别为（91.70±1.47）%、（80.96±5.02）%和（40.69±1.16）%。此外，在乳液凝胶中加入PUL可以提高乳液凝胶的硬度、保水能力和储存稳定性。本研究结果为优化AST在乳状凝胶中的生物可及性提供了一种可行的方法。这为AST作为功能性食品的高效应用提供了可能。

Regulation of whey protein emulsion gel's structure with pullulan to enhance astaxanthin bioaccessibility

In this study, the potential of using an emulsion gel based on whey protein concentrate (WPC) and pullulan (PUL) to encapsulate and deliver astaxanthin (AST) was investigated. PUL concentration was observed to affect the microstructure of WPC/PUL/AST emulsion gels, and the performance of emulsion gels was evaluated by encapsulation efficiency, simulated gastrointestinal digestion, storage stability, hardness, and water holding capacity tests. The WPC/PUL/AST emulsion gels had the highest encapsulation efficiency, gastrointestinal digestion retention, and bioaccessibility of (91.70 ± 1.47) %, (80.96 ± 5.02) %, and (40.69 ± 1.16) % at 2.0 % PUL concentration, respectively. Furthermore, adding PUL to the emulsion gels improved their hardness, water holding capacity, and storage stability. The findings suggested a potential method to optimize the bioaccessibility of AST in emulsion gels. It provided the possibility for the efficient application of AST as a functional food.

期刊介绍： Carbohydrate Polymers stands as a prominent journal in the glycoscience field, dedicated to exploring and harnessing the potential of polysaccharides with applications spanning bioenergy, bioplastics, biomaterials, biorefining, chemistry, drug delivery, food, health, nanotechnology, packaging, paper, pharmaceuticals, medicine, oil recovery, textiles, tissue engineering, wood, and various aspects of glycoscience. The journal emphasizes the central role of well-characterized carbohydrate polymers, highlighting their significance as the primary focus rather than a peripheral topic. Each paper must prominently feature at least one named carbohydrate polymer, evident in both citation and title, with a commitment to innovative research that advances scientific knowledge.
