There is a multi-step process in making lactose-free milk. Once the processor has received the milk from the farm, they pasteurize and standardize it to the desired milk fat percentage (skim, 1%, 2%, or 3.25%). The milk is then stored in a large cooling tank, where the appropriate amount of lactase enzyme is added. The enzyme works to remove the lactose from the milk. The milk is then tested to verify that it is lactose free, re-pasteurized, and then packaged. Lactose free milk is a great way for people with lactose intolerance to enjoy still dairy products.
