Researchers at the Swiss Higher Technical School of Zurich (ETH Zurich) and the University of Applied Sciences and Arts of Northwest Switzerland (FHNW) have developed a food technology that gives chocolate an iridescent sheen without the use of artificial additives.
It all started when a group of scientists decided to create an unusual colored chocolate. The idea of applying a special edible coating on top of the chocolate was almost immediately rejected due to the complexity and time consuming, which is unacceptable in conditions of mass production.
The next idea - to cover the chocolate with a shiny, iridescent layer - was loved by everyone. First, the team achieved a slight flicker, and then a full-fledged glow. The technique is similar to the one that allows the chameleon to change the color of his skin.
Scientists are currently working on a shape that will allow them to create multiple pieces of colored chocolate at a time. In addition, they are negotiating with large chocolate manufacturers and even expect to create a small enterprise. All this means that unusual chocolate may soon appear on store shelves.
