What's the ingredient list say? Some stabilizers and such can do that, if they aren't mixed properly.
I don't do it for a living, but I have family that run dairy. One of the things used for consistency and texture is carageenen (spelling?). It kinda looks like that when it's saturated. It's a moss or algae extract iirc (too lazy to look it up, but it's something like that, carageen is the original plant).
So, that would be my best guess, and if that's in the ingredients, that's almost certainly what it is.
