In this work, a bottom-up approach based on the study of polyelectrolyte interactions was performed in order to evaluate the effect of Prosopis alba exudate gum as novel excipient for fish oil encapsulation in composed calcium-alginate-chitosan beads. Emulsion and beads properties such as oil distribution, encapsulation efficiency, yield, microstructure and thermo-oxidative protection were evaluated. Alginate and gum exert a synergistic effect on emulsion stability properties, which conducted to better oil distribution in the beads and higher encapsulation efficiencies (98%) and yield (89%). The positive effect of including the gum as wall material was observed in terms of a higher oil retention capacity of the alginate beads, improved oxidative thermal stability and better microstructural features. Present results are promising and allowed considering P. alba gum as a novel non-conventional polyelectrolyte for improving Ca-alginate beads microstructure and stability with the added benefit of taking advantage of an available resource currently untapped.
在这项工作中，采用了一种自下而上的方法，基于聚电解质相互作用的研究，以评估白杨 exudate 胶作为新型赋形剂在复合海藻酸钠-壳聚糖珠粒中包封鱼油的效果。评估了乳液和珠粒的性质，如油的分布、包封效率、产率、微观结构和热氧化保护。海藻酸钠和胶在乳液稳定性方面表现出协同作用，这导致珠粒中油的分布更好，包封效率（98%）和产率（89%）更高。将胶作为壁材包含在内，在提高海藻酸钠珠粒的油保持能力、改善氧化热稳定性和更好的微观结构方面表现出积极的效果。目前的结果很有前景，这使得白杨胶可以作为一种新型的非传统聚电解质，用于改善 Ca-海藻酸钠珠粒的微观结构和稳定性，同时还可以利用目前尚未开发的可用资源。
