Carvacrol has been encapsulated in polyvinyl alcohol (PVA) matrices by electrospinning and casting. Aqueous solutions containing 15% PVA and 15% carvacrol with respect to polymer have been used, containing or not Tween 85 at 0.3 g/100 g carvacrol. Electrospun mats exhibited beads and thin fibres which became thinner and interrupted when carvacrol was present and retained up to 83% of this compound. The encapsulation efficiency in the electrospun mats decreased in the presence of surfactant, reaching values similar to those of casting (75–77%). The electrospun, surfactant free material was practically amorphous with 40% of the total carvacrol non-thermally releasable. In contrast, when surfactant was present and in cast material, with 40% crystallinity, the strongly bonded carvacrol ratio decreased. Specific PVA - phenolic hydroxyl interactions played an important role in the degree of carvacrol retention in the matrices, which depended on surfactant's presence and processing method.

香芹酚已通过静电纺丝和浇铸法封装在聚乙烯醇（PVA）基质中。已经使用相对于聚合物含有15％PVA和15％香芹酚的水溶液，其含有或不含有0.3g / 100g香芹酚的Tween 85。电纺垫呈现出珠粒和细纤维，当存在香芹酚时会变细并中断，并保留高达83％的该化合物。在表面活性剂存在下，电纺垫的封装效率降低，达到与铸造相似的值（75-77％）。电纺丝，不含表面活性剂的材料实际上是无定形的，总香芹酚的40％是不可热释放的。相反，当表面活性剂存在于铸造材料中时，结晶度为40％时，强键香芹酚比率降低。
