摘要:为改善皮革的特殊气味并提升其应用性能,以玉米醇溶蛋白(Zein)、艾叶香精(AAE)以及普兰尼克 F127
等为原料,通过反溶剂法制备缓香型玉米醇溶蛋白微胶囊(AAE@ZMs)乳液,再将 AAE@ZMs 乳液与成膜剂
己内酰胺改性酪素复配后应用于皮革涂饰。结果表明,Zein 与 F127、AAE 和戊二醛通过化学交联和氢键相互作
用,同时 F127 和 AAE 可使 Zein 中的氨基酸重排并发生荧光猝灭。当 Zein 和 AAE 质量分别为 0.1 g 和 0.01 g
时,制得的 AAE@ZMs 乳液中微胶囊平均粒径约为 298.6 nm,且具有较好的分散性和稳定性,AAE@ZMs 对香
精的包覆率和负载率分别可以达到 73.2%和 5.8%,微胶囊中的 AAE 在良溶剂中释放 120 h 后的累积释放率约为
83.1%。将复配后的 AAE@ZMs 乳液应用于皮革涂饰后,涂饰革样中 AAE 的释放周期为 6 周,对金黄色葡萄球
菌和大肠杆菌均具有较好的抑制效果,同时涂饰革样还展现出较好的机械性能。

Abstract: In order to improve the special odor of leather and enhance its application performance, sustained
release zein microcapsule (AAE@ZMs) emulsion was prepared by anti-solvent method using zein,
Artemisia argyi essence (AAE) and Pluronic F127 as raw materials. Then, AAE@ZMs emulsion and
film-forming agent caprolactam modified casein were mixed and applied to leather finishing. The results
show that zein interacted with F127, AAE and glutaral through chemical crosslinking and hydrogen
bonding. Meanwhile, F127 and AAE could rearrange amino acids in zein and cause fluorescence quenching.
The prepared AAE@ZMs emulsion had good dispersibility and stability with an average particle size of
about 298.6 nm when the masses of zein and AAE were 0.1 g and 0.01 g, respectively. The encapsulation
and loading efficiency of AAE@ZMs emulsion could reach 73.2% and 5.8%, and the accumulative release
rate was about 83.1% after releasing for 120 h. After the AAE@ZMs emulsion was used for leather
finishing, the release cycle of AAE in the finished leather was 6 weeks. Moreover, the finished leather
samples showed good inhibitory effect on Staphylococcus aureus and Escherichia coli, and possessed
expected mechanical properties.
