Holographic rainbows make chocolate look more delicious

As if chocolate wasn't good enough already, a Swiss company has figured out a way to decorate it with additive-free holograms.

Chocolate may have originated in the ancient cultures of Mesoamerica, but it's common wisdom that Switzerland produces some of the world's finest chocolate. And now the country is making it look amazing, too. A company called Morphotonix in Lausanne has figured out a way to create holographic patterns on its surface -- without using any additives at all.

This means the holographic effects are actually created out of chocolate. First, the team creates a metal mould. This has microstructures etched in that use texture to diffract light, creating the holographic effect. From this metal master mould, a plastic mould is made. The liquid chocolate is then precision injection-moulded, and the microstructures are imprinted on the chocolate's surface.

The process works with both dark and milk chocolate, but the chemical makeup of some varieties means it doesn't always work. "We have been testing it with many types of chocolate. Sometimes it works great and sometimes no matter how hard we try it doesn't mould," Morphotonix CEO Veronica Savu told New Scientist.

The company is currently working to bring the product to market in collaboration with a German chocolate mould manufacturer.

We hope it comes soon. It looks good enough to eat.
