Edible beeswax coating that lets loose every last drop of liquid

Researchers have created a “superhydrophobic” coating made out of beeswax that easily slicks away viscous liquids like syrup and ketchup. Superhydrophobic coatings are not new, but they’re typically made with fluorocarbons. These materials, while generally safe in low doses, are labeled as “emerging contaminants”.
The chemical properties of the beeswax coating are similar to non-sticky fluorocarbons, but even at extremely high doses, they are safe to ingest. The researchers came up with a way to spray the coating onto a surface by first dissolving the wax. An article about the research is published in Applied Materials and Interfaces (News Item Colorado State University, 3 August 2016).
