6. Is there pig fat in the soft serve?

This is one of the most commonly asked questions about McDonald's food in Australia, according to Jonathon Pitt, a McDonald's franchise owner in Queensland.
"Absolutely, there is no pig fat in our soft serve — or in our shakes, for that matter," Pitt says in a video on how the frozen yogurt is made. "The only animal products in our soft serve are the dairy ingredients themselves."
That includes milk, cream, and milk solids. Sugar is added for sweetness and emulsifiers are used to keep the mixture from separating.
"Vegetable gums are also used to give it a thick, smooth texture," Pitt says. "And finally, a little vanilla flavor is added."
