One other point about excessive lipase activity is that while the milk may smell and/or taste bad, there's nothing really wrong with it. If the baby won't take it, then yes, the milk can be scalded to halt the lipase activity. But scalding also kills many of the living immune cells and reduces the antibacterial properties, so if you don't have to, then it's best to avoid it. Milk that has high lipase activity doesn't really smell "bad" like cow's milk gone sour - it has a more metallic or soapy taste and smell - which doesn't smell like milk to us, so we classify it as "bad", but it's actually quite different from milk that has truly soured. Long and short, if the baby will still take the milk, go ahead and use it (as long as it's really lipase and not souring for some other reason - but anyone who has smelled breastmilk that has truly soured will be able to tell).
