For instance, the blueberry pancake mix from Krusteaz does not have blueberries or fruit of any kind in a long list of ingredients. It does have a disclaimer that says “artificially flavored” and “imitation blueberries,” which in the Krusteaz pancake mix are made of palm oil, cellulose gum, and several dyes.
What about Kellogg’s Blueberry Muffin Frosted Mini-Wheats? Blue on the outside, but the only blue thing in the cereal is a dye called blue 2 lake. A Kellogg’s company spokesperson says, “The term ‘Blueberry Muffin’ is used to describe the flavor, and the product is labeled in compliance with laws and regulations.”
Consumer Reports found some other products that prominently display blueberries but have only blueberry juice in them, and that comes way down on the list of ingredients, behind sugar and corn syrup. And Ocean Spray’s Blueberry Craisins are not dried blueberries at all, but cranberries “infused” with blueberry juice.
As with most fruits and vegetables, Consumer Reports says it’s best to eat blueberries before they or their juice end up in packaged products.
