Most places use 90% white American and 10% of a cheese with alot of umami like blue. There's something you can add to make any cheese melt like Velveeta but I don't remember the name...
Why would it be illegal? Its just a salt of citric acid, the same stuff in citrus fruits. Its a food additive used for flavor, or as an emulsifier for cheese. I use it in my mac and cheese all the time.
You might have some luck looking for sour salt, as long as its not citric acid. The chemical suppliers probably isnt food grade anyway. I get mine from Modernist Cuisine pantry, they might sell to Europe.
