The Swiss chocolate-making dates to the 17th Century. Now a chocolatier in Switzerland is taking the candy into the future. Lausanne-based Morphotonix has found a way to etch microstructures into chocolate that refract light to produce holographic images. No stickers, no additives, no paint. The holograms work similar to those etched into credit cards, except these are edible.
Sweet Structure Engineered From Chocolate
The company starts by carving a microscopic pattern into a master mold made from metal. That mold in turn is used to create a plastic mold in which the chocolate is poured. Dark and milk chocolate varieties have been made, but not all chocolate is made equal.
"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 mold," Morphotonix CEO Veronica Savu told New Scientist.
Climate Change Threatens Coffee And Chocolate
The chocolates will be unwrapped at the Interpack packaging trade fair in Düsseldorf, Germany this week. Yum.
