Scientists have long been looking for a way to protect ancient Egyptian papyrus from the effects of bacteria and fungi and at the same time not damage valuable artifacts. Recently, researchers managed to find such a method – wasabi.
Researchers have found a surprisingly simple yet effective way to protect ancient Egyptian papyrus from bacteria and fungi. Arkeonews writes that scientists have discovered that ordinary wasabi not only destroys microbes, but also strengthens papyrus while preserving its original color.

Researchers led by Hanadi Saad and his team investigated more deeply the impact of wasabi on these valuable historical documents. Papyrus works of rich historical and cultural importance are under threat due to the destructive effects of fungi.
Previous methods of cleaning and preserving these ancient texts had their problems. Although the chemicals were effective against microbes, they sometimes damaged the papyrus fiber or changed the pigments of the paintings. Physical methods such as ultraviolet rays or heat cannot always ensure complete removal of biological agents without causing secondary damage.
The Grand Egyptian Museum team’s solution was to use wasabi paste to create protective layers for the papyrus. In a controlled experiment, papyrus samples with a variety of pigments, including red, yellow and blue, were exposed to simulated microbiological contamination.
Remarkably, after 72 h of wasabi treatment, all microbial growth was eliminated and 100% inhibition efficiency was achieved on both stained and unstained papyrus samples.
Moreover, the process increased the tensile strength of the papyrus by 26% without changing its color or appearance. Detailed analysis confirmed minimal chemical changes and highlighted the noninvasive nature of the treatment.
Important
This method not only offers a safe and environmentally friendly way to preserve archaeological papyri, but also ensures the longevity of these priceless relics without compromising their integrity.
