If you look at a package of M&Ms, one of the most popular candies in the US, you’ll see some familiar ingredients: sugar, skimmed milk powder, cocoa butter. But you’ll see many more that aren’t so recognizable: gum arabic, dextrin, carnauba wax, soya lecithin and E100.

There are 34 ingredients in M&Ms, and, according to Mars, the company that produces the candy, at least 30 countries – from Ivory Coast to New Zealand – are involved in supplying them. Each has its own supply chain that transforms the raw materials into ingredients – cocoa into cocoa liquor, cane into sugar, petroleum into blue food dye.
