Abstract This work concern with the use of a novel mesquite gum as a biopolymer alternative in desert areas of northern Argentina. The species collected was taxonomically identified as Prosopis nigra based on morphological/histological characteristics. Its gummy exudate was partially purified (PN-biopolymer) showed antioxidant activity and good emulsifying properties. The emulsions at 10% PN-biopolymer showed EI24 values greater than 0.50 even after a thermal shock with a relatively high oil volume fraction of 50%. pH-stability tests showed a correlation between fatty acid unsaturations and droplet size distribution. Then, the use of PN-biopolymer-alginate blend was evaluated for fish oil encapsulation. An external gelation process was optimized showed a significant dependence of the responses evaluated (EI24 and sphericity factor) towards the interaction between both polymers and the water/oil ratio. Thus, for a fixed oil/water ratio of 0.25, the appropriate amount of both polymers allowed to obtain an EI24 of 96.1% with sphericity factors of 0.971. The PN-biopolymer played a key role in the orderly alginate crosslinking by control emulsion stability. Based on this results, this biopolymer is a renewable, sustainable, and local resource for industrial applications.

用于油包封的可再生生物基聚合物的混合物：通过黑夜香树的胶状渗出物控制微胶囊的乳液稳定性和支架

摘要 这项工作涉及在阿根廷北部沙漠地区使用新型豆科灌木胶作为生物聚合物替代品。基于形态学/组织学特征，收集的物种在分类学上被鉴定为黑夜蛾。其胶状渗出液经过部分纯化（PN-生物聚合物），显示出抗氧化活性和良好的乳化性能。即使在油体积分数相对较高的 50% 的热冲击之后，10% PN-生物聚合物的乳液也显示出大于 0.50 的 EI24 值。pH 稳定性测试表明脂肪酸不饱和度与液滴尺寸分布之间存在相关性。然后，评估了 PN-生物聚合物-海藻酸盐混合物在鱼油封装中的应用。优化的外部凝胶化过程表明，评估的响应（EI24 和球形因子）对两种聚合物和水/油比之间的相互作用有显着依赖性。因此，对于 0.25 的固定油水比，适当量的两种聚合物允许获得 96.1% 的 EI24，球形因子为 0.971。PN-生物聚合物通过控制乳液稳定性在有序的海藻酸盐交联中起关键作用。基于这一结果，这种生物聚合物是一种可再生的、可持续的、工业应用的本地资源。PN-生物聚合物通过控制乳液稳定性在有序的海藻酸盐交联中起关键作用。基于这一结果，这种生物聚合物是一种可再生的、可持续的、工业应用的本地资源。PN-生物聚合物通过控制乳液稳定性在有序的海藻酸盐交联中起关键作用。基于这一结果，这种生物聚合物是一种可再生的、可持续的、工业应用的本地资源。
