Carrot, hibiscus, radish, and lemon — food for rabbits, and now ingredients for candy. Driven by strong consumer demand to go “natural,” Nestlé has started to use these natural alternatives to provide color or flavor in popular products such as Rolo and Smarties. And, by doing so, the company has become the first major confectionery manufacturer in the U.K. to remove all artificial ingredients from its products — all 79 of the confectionery products sold in the region now are free of artificial colors, flavors and preservatives.
