采用电喷雾雾化法制备了百里香酚和香芹酚(TC)的淀粉/水溶性黄芥子胶乳纳米胶囊。乳液被电喷雾，目的是产生具有TC控制释放行为的纳米胶囊，用于抗菌包装应用。为了了解水溶性黄芥末胶乳(WSM)对纳米胶囊的影响，考察了乳状液的粘度、形态、包封率、分子相互作用和释放动力学。表面和内部形态分析表明，纳米胶囊是无孔的，表面收缩最小，在固体壁层中有内部多核球体。包封率在61.17%~84.10%之间，随TC含量的增加而增加。傅里叶变换光谱证实了墙体材料之间的分子相互作用。囊化TC(30%w/w)在120h内的释放动力学符合Fickian扩散机制和控释模式，结果表明，WSM的加入可以调节生物活性物质的释放动力学，实现控释模式。
Starch/water soluble yellow mustard mucilage nanocapsules loaded with thymol and carvacrol (TC) were developed using electrospray atomization. Emulsions were electrosprayed, aiming to generate nanocapsules with a controlled release behavior of TC for antimicrobial packaging applications. To understand the effect of water soluble yellow mustard mucilage (WSM) on the nanocapsules, the emulsion viscosity, morphology, encapsulation efficiency, molecular interactions, and release kinetics were evaluated. Surface and internal morphological analysis revealed that nanocapsules were non-porous with minimal surface shrinkages and had inner multicore spheres within a solid wall layer. Encapsulation efficiency ranged from 61.17 to 84.10 %, increasing at higher TC contents. Fourier transform spectroscopy confirmed the molecular interaction between wall materials. The release kinetics of encapsulated TC (30 % w/w) followed a Fickian diffusion mechanism and a controlled release pattern up to 120 h. Results indicated that the addition of WSM can modulate the release kinetics of bioactives and achieve a controlled release pattern.
