Wasabi has been displayed substantial fungicidal behavior for the disinfection of bio-deteriorated non-painted archaeological papyri. Therefore, in this study for the first time the interference of Wasabi with different pigments of painted papyrus has been studied. Microbiological, mechanical, physical and chemical evaluations were carried out using various spectroscopic, tensile tester and microscopic tools. Wasabi vapors treatment for 72hs (2.5%) has eradicated the microbial growth of all the examined infected painted and non-painted papyri with inhibition efficiency of 100%. The tensile strength of the treated papyri recorded enhancement by 26%, while maintained the color of painted and non-painted papyri without any noticeable change (ΔE < 1). Moreover, surface morphology of treated papyri has been evaluated and there was no change recorded. Additionally, FT-IR and EDX analyses revealed negligible chemical changes were attained. Interestingly, upon long term treatment evaluation, which has been conducted based on the artificial aging of approximately 100 years, the papyrus samples remained unchanged. Therefore, this study presents a green and cost-effective conservation approach for long-term preservation of painted archaeological papyri.

芥末在对生物腐烂的未上漆的考古纸莎草消毒时表现出显着的杀菌作用。因此，本研究首次研究了芥末对彩绘纸莎草不同颜料的干扰。使用各种光谱仪、拉伸测试仪和显微工具进行微生物、机械、物理和化学评估。芥末蒸气处理 72 小时（2.5%）已根除所有受检受感染的涂漆和未涂漆纸莎草的微生物生长，抑制效率为 100%。经过处理的纸莎草纸的拉伸强度提高了 26%，同时保持了涂漆和未涂漆纸莎草的颜色，没有任何明显的变化 (ΔE < 1)。此外，对处理过的纸莎草纸的表面形态进行了评估，没有发现任何变化。此外，FT-IR 和 EDX 分析显示，化学变化可以忽略不计。有趣的是，根据大约100年的人工老化进行的长期处理评估，纸莎草样品保持不变。因此，本研究提出了一种绿色且具有成本效益的保护方法，用于长期保存彩绘考古纸莎草纸。
