以百里香酚（THY）/γ-环糊精（γ-CD）包合物（IC）为包合物，采用静电纺丝法制备了玉米醇溶蛋白纳米纤维网（zein-THY/γ-CD-IC-NF）。通过X射线衍射（XRD）、热重分析（TGA）、核磁共振氢谱（H-1 NMR）和计算技术证实了THY/γ-CD-IC（1：1和2：1）的形成。THY/γ-CD-IC（2：1）比THY/γ-CD-IC（1：1）具有更高的保存率和稳定性。值得一提的是，如在TGA中观察到的，玉米醇溶蛋白-THY/γ-CD-IC-NF（2：1）保留了更多的THY，并且THY/γ-CD-IC（2：1）的稳定性更高，如通过建模研究所示。因此，玉米醇溶蛋白-THY/γ-CD-IC-NF（2：1）比玉米醇溶蛋白-THY-NF和玉米醇溶蛋白-THY/γ-CD-IC-NF（1：1）释放更多的THY。玉米醇溶蛋白-THY/γ-CD-IC-NF（2：1）的抗菌活性高于玉米醇溶蛋白-THY-NF和玉米醇溶蛋白-THY/γ-CD-IC-NF（1：1）。结果表明，玉米醇溶蛋白-THY/γ-CD-IC-NF（2：1）对肉样品上的细菌生长的抑制效果最好。这些纤维网显示出作为抗菌食品包装材料的潜在应用。(C)2017爱思唯尔有限公司版权所有
Thymol (THY)/gamma-Cyclodextrin(gamma-CD) inclusion complex (IC) encapsulated electrospun zein nanofibrous webs (zein-THY/gamma-CD-IC-NF) were fabricated as a food packaging material. The formation of THY/gamma-CD-IC (1:1 and 2:1) was proved by experimental (X-ray diffraction (XRD), thermal gravimetric analysis (TGA), H-1 NMR) and computational techniques. THY/gamma-CD-IC (2:1) exhibited higher preservation rate and stability than THY/gamma-CD-IC (1:1). It is worth mentioning that zein-THY/gamma-CD-IC-NF (2:1) preserved much more THY as observed in TGA and stability of THY/gamma-CD-IC (2:1) was higher, as shown by a modelling study. Therefore, much more THY was released from zein-THY/gamma-CD-IC-NF (2:1) than zein-THY-NF and zein-THY/gamma-CD-IC-NF (1:1). Similarly, antibacterial activity of zein-THY/gamma-CD-IC-NF (2:1) was higher than zein-THY-NF and zein-THY/gamma-CD-IC-NF (1:1). It was demonstrated that zein-THY/gamma-CD-IC-NF (2:1) was most effective in inhibiting the growth of bacteria on meat samples. These webs show potential application as an antibacterial food packaging material. (C) 2017 Elsevier Ltd. All rights reserved.
