Tyrosol, a powerful antioxidant present in high amounts in olive oil and mill wastes, possesses relevant health benefits due to its antioxidant properties. Therefore, tyrosol is a promising compound for further incorporation in functional foods. However, its incorporation in food matrices is limited due to its hydrophilicity. Therewith, encapsulation by double emulsion solvent evaporation emerges as an alternative for its protection and incorporation in lipophilic matrices, as some foods. This work aimed to encapsulate tyrosol in alternative carriers—poly(D,L-lactide-co-glycolide), ethylcellulose, and polycaprolactone, using two theoretical loading contents (TLC) (5% and 10% w/w). Tyrosol was efficiently incorporated in the selected polymer-carriers. Significant effects of the TLC were found on the product yield, encapsulation efficiency, thermal stability, morphology, and on the particle size distribution. This is the first study regarding the encapsulation of tyrosol and brings new insights concerning the encapsulation of antioxidants for further incorporation in food matrices.

酪醇是一种强效抗氧化剂，大量存在于橄榄油和磨碎废料中，由于其抗氧化性能，具有相关的健康益处。因此，酪醇是将其进一步掺入功能性食品中的有前途的化合物。然而，由于其亲水性，其在食品基质中的掺入受到限制。因此，出现了通过双乳液溶剂蒸发的封装作为其保护和掺入亲脂性基质（如某些食品）的替代方法。这项工作的目的是包封酪醇在替代的载体-聚（d，L丙交酯-共-glycolide），乙基纤维素和聚己内酯，使用两个理论负载内容（TLC）（5％和10％瓦特/瓦特）。酪醇被有效地掺入所选的聚合物载体中。发现TLC对产物收率，包封效率，热稳定性，形态和粒径分布具有显着影响。这是有关酪醇包封的第一项研究，并带来了有关将抗氧化剂包封以进一步掺入食品基质的新见解。
