High Lipase Milk

Hi ladies. My milk has the soapy smell when I defrost it... baby boy isn’t taking a bottle great so I fear it’s because of the high lipase in my milk. What have you all done to help with this issue? I know I can scald the milk before freezing, but that would mean my whole freezer stash isn’t good, and it also takes away some of the nutrients. Should I try mixing it with half fresh milk? Or, I don’t really want to do this, but half formula? (He’s never had any formula and it’s EXPENSIVE lol). I exclusively breastfeed but go back to work August 5th so we have to figure this bottle thing out. Thanks!
