I had this same issue with too much lipase (soapy tasting breastmilk), and was scalding all of my pumped milk with a bottle warmer. However, after about 6 weeks I one day forgot to scald a bottle while at work, and tasted it 2 days later, and it tasted fine! So apparently the condition can come and go. I don't know if this is related, but I did stop taking Omega 3-6-9 supplements as soon as I discovered the excessive lipase, since someone had thought they might contribute to the problem. I'm curious if anyone else notices this effect?
