Abstract

Protein-based nanomaterials are among the most promising materials for gas adsorption due to their green properties and high surface area. However, the performance of these materials is susceptible to variations in temperature. This study examined the effects of postheat treatment (40 °C, 0–9 h) on the dynamic network valence bonds of zein nanofibers (zeinNFs) and their ethylene adsorption performance using theoretical simulations and experimental studies. With increasing durations of postheat treatment, up to 9 h, the diameter of zeinNF-9 reduced by 42.11%, the structure of the zein protein stretched, the total sulfhydryl groups increased by 13.03%, and the ethylene adsorption efficiency increased to 7.05 ± 0.05 mg/m³/h. Furthermore, incubation of TaiPo pear with zeinNF-9 for 20 days resulted in the most effective preservation performance. The above results demonstrate that zeinNF-9 is a highly efficient and environmentally friendly material for ethylene adsorption. These characteristics render it greatly promising for practical applications in fruit preservation.

通过后热处理对 ZeinNFs 中的动态网络价键进行自我修饰：制备高效环保的乙烯吸附剂

基于蛋白质的纳米材料具有绿色特性和高表面积，是最有前途的气体吸附材料之一。然而，这些材料的性能易受温度变化的影响。本研究通过理论模拟和实验研究，探讨了后热处理（40 °C，0-9 小时）对玉米蛋白纳米纤维（zeinNFs）的动态网络价键及其乙烯吸附性能的影响。随着后热处理时间的延长，至9 h时，ZeinNF-9的直径减小了42.11%，玉米蛋白结构拉伸，总巯基增加了13.03%，乙烯吸附效率提高到7.05 ± 0.05 mg/m3/h。此外，将太婆梨与玉米蛋白 NF-9 培养 20 天后，其保鲜效果最佳。上述结果表明，zeinNF-9 是一种高效、环保的乙烯吸附材料。这些特点使其在水果保鲜的实际应用中大有可为。
