When Starbucks' version popular drink arrives, it will include real pumpkin and ditch caramel coloring, a controversial additive. Meanwhile, Panera will debut a version that replaced some artificial preservatives with some natural ones.
"It was actually a pretty simple tweak. It was pretty clean to begin with," Dan Kish, Panera's senior vice president of food, told CNBC.
The move comes as Panera continues removing artificial colors, flavors, sweeteners and preservatives from its food, a pledge it aims to fulfill by next year. The chain also said it would add more bottled beverage options that are free of these artificial ingredients and is testing 'clean' versions of its vanilla, caramel and chocolate syrups, used in other coffee beverages.
