About 80 years ago, food scientists introduced the world to white chocolate. Until this week, it was the last new kind of chocolate to enter the world market. But now, scientists have invented a pink-colored chocolate. It joins the likes of white, dark, and milk chocolate. A chocolate manufacturer in Switzerland launched the new product Tuesday in Shanghai, China. The chocolate company Barry Callebaut says that the pink color comes from the ruby cocoa bean. The color, the company adds, is natural. It has an intense and fresh berry taste. The Financial Times reports that ruby cocoa beans grow in Ecuador, Brazil, the Ivory Coast and other countries. Scientists worked for more than 10 years to develop ruby chocolate.
