According to the OU which certify some Coca-Cola products the latest Coke drink contains dairy products.
This product contains a dairy ingredient. According to the Coca-Cola Company, this ingredient does not contain proteins from milk which make it allergenic to some people. Coca-Cola Blak is produced under the supervision of the Orthodox Union and is kosher-dairy when bearing the OU-D symbol.
It also means that you can’t wash down your hamburger with a Coke Blak, or have a a Blak at the Ballpark with your Kosher Dog. Is it actually milchik as in, cannot be eaten within a given time after consuming meat? I’ve written to OU to find out.
BTW The orange in Orange Listerine comes from a Cochineal beetle. But you can still use it anyway, unless you’re a vegan.
