Hi, I have a 12 week old who I have been breastfeeding. I have also been expressing any excess milk and now have about 30 bags in the freezer. We have fed the baby some of the frozen milk and he took it fine. However, we gave him some the other day and as there was a little left, thought it was the perfect time for me and my husband to try it. It was awful! Smelt bad and tasted horrible - leaving a really bad taste in the mouth. The only way I can describe the taste and smell is like regurgitated milk/vomit. I was horrified thinking that all of my milk has gone off, especially when I was so careful in expressing into sterilised equipment and storing it in special breast milk freezer bags - always within 24 hours, if not immediately after expressing.
I did some research online and found the following on this forum:
"Sometimes thawed milk may smell or taste soapy. This is due to the breakdown of milk fats. The milk is safe and most babies wil still drink it. If there is a rancid smell from high lipase (enzyme that breaks down milk fats) activity when the milk has been chilled or frozen, the milk can be heated to scalding (bubbles around the edges, not boiling) after expression, then quickly cooled and frozen. This deactivates the lipase enzyme. Scalded milk is still a healthier choice than commercial infant formula."
I also found this forum posting:
However, how do I know if I have an excessive amount of lipase? and is this stored milk still any good?
I have now started to scald the milk in case this helps, however, I don't like the idea of my baby having to drink the unscaled milk, especially if it tastes that bad but, if it is still good, I am also reluctant to throw it out. I've contacted one of my local hospitals to ask for their advice as well as a local breastfeeding supporter however, no-one has really been able to give me a definitive answer on any of this. Is this still ok for my baby to drink and is there anything I can do to get rid of the smell/taste of the already frozen milk - and/or anything further I can do to prevent it from happening? Also, how do you know if you have excess Lipase?
Sorry for all the questions however, I am reluctant to throw out all of that milk, if it is still good.
