Did Hershey chocolate change their recipe?

YES.

Sometime in fall 2007, Hershey changed their recipe, unannounced.

I have an older package of Hershey's Milk Chocolate Kisses from summer 2007. The ingredients are: Milk chocolate (sugar, milk, cocoa butter, chocolate, soy lecithin, and vanillin, artificial flavor). I also have a newer bag from just before Halloween 2007. The ingredients are: Milk chocolate (sugar, milk, chocolate, cocoa butter, LACTOSE, MILK FAT, soy lecithin and PGPR, EMULSIFIERS, and vanillin, artificial flavor). PGPR is a food additive used to replace real chocolate. It is cheaper to produce. Major chocolate manufacturers, including Hershey, are currently lobbying the FDA to allow non-chocolate to be labeled as chocolate. I encourage everyone to stop supporting companies who are deceptive to consumers. Natural stores such as Trader Joe's, Whole Foods Market, and the brand Ghiradelli still make real chocolate.
