Researchers made a chewing gum that kills over 95% of viruses in saliva.
It could let you prevent disease transmission just by chewing.
Researchers at the University of Pennsylvania have engineered an experimental chewing gum designed to trap and neutralize viral particles directly in the mouth.
By utilizing specialized proteins—including plant-grown ACE2 to target SARS-CoV-2 and FRIL derived from lablab beans for influenza and herpes—the gum acts as a molecular decoy. When an infected individual chews the gum, these proteins bind to the virus, preventing it from entering human cells and significantly lowering the viral load found in saliva. This reduction is critical for limiting the spread of pathogens when talking, coughing, or sneezing.
Laboratory experiments indicate that just 40mg of this bean-based gum can reduce viral concentrations of influenza and herpes by more than 95%. Beyond its immediate effectiveness, the product is designed for practical, long-term use; it remains stable at room temperature for over two years and adheres to FDA clinical-grade specifications. As the technology moves into human clinical trials in early 2025, health experts view it as a potential breakthrough for protecting high-risk environments like schools, dental offices, and public transit during seasonal outbreaks.
