采用乳液交联法制备了一种绿色缓释材料，用于包裹富马酸二甲酯（DMF）。微球的平均尺寸为20-150 μ m。最高包封率和装载率分别为85.7%和13.2%。DMF在磷酸盐缓冲盐水中的释放遵循Fickian扩散。抑菌圈测试结果表明，载DMF微球的抑菌效果明显优于壳聚糖微球。与对照组相比，处理组果实失重率降低不显著，贮藏期延长，品质稳定。因此，成功制备了DMF缓释微球，在果蔬保鲜中具有广阔的前景和开发价值。
A green sustained delivery biomaterial was prepared to encapsulate dimethyl fiimarate (DMF) by an emulsion cross-linking method for sustained release. The average size of the microspheres was 20-150 mu m. The highest encapsulation efficiency and loading efficiency were 85.7 and 13.2%, respectively. The release of DMF in phosphate buffer saline followed a Fickian diffusion. In addition, the results of inhibition zone showed that DMF-loaded microspheres exhibited antimicrobial and antifungal properties much better than those of CS microspheres. Furthermore, weight loss of treated fruit was reduced insignificantly, and storage time was extended with the stable quality of litchi as compared with that of the control group. Thus, the microspheres were synthesized successfully as a sustained delivery system for DMF, which might have broad prospect and development value in preservation of fruits and vegetables.
