Because after degreasing, the taste and flavor of milk will be greatly reduced, and it tastes a bit like adding milk to water. And because of the processing technology, skim milk may have the special taste of skim milk. It may taste worse than water. But even if defatted, there will still be fat, which seems to be below 2%.
