Will a hologram make this chocolate too pretty to eat?

Soon, chocolates may no longer be just a treat for your sweet tooth – it could be a treat for the eyes, too, after a Swiss company found a way to imprint holograms on chocolate.

Lausanne-based Morphotonix developed a method of imprinting the holograms into the chocolates by etching microstructures into the chocolate, New Scientist reported.

The advantage of the new method is that it requires no additives to create the holographic effect, the report said.

However, Morphotonix CEO Veronica Savu said the method does not quite work for all types of chocolate, at least for now.

“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,” Savu told New Scientist.

Morphotonix started work on the technology in 2012. It is now working with a German chocolate mold manufacturer to bring it to market.

On the other hand, Savu said they are considering using a similar technique for molds for proof of authenticity of other products.

"Instead of having a holographic sticker you can have the hologram directly embedded into any rigid plastic object," she said.

New Scientist likened the method for creating the hologram to that of the security hologram on a credit card, "though chocolate is trickier to work with."

In creating the hologram, Morphotonix made an etching into a metal master mold, which is then used to make plastic molds that will shape the chocolate. — LBG, GMA News
