Lipase in Breastmilk

My SIL is experiencing what sounds like a excess lipase issue with expressed breastmilk. Has anyone out there figured out a good system for scalding breastmilk for storage after pumping at work? I am pretty sure she has a microwave available, but the thread on the LLL site is clear that that is very contentious issue. Any other brilliant ideas out there? Thanks!!

What can I do next?

So What Happened?

My SIL's pediatrician and lactation consultants were not very helpful with this, so THANK YOU for your comments and suggestions, she so appreciates them. The milk-scalding system suggested by another mama is now in effect and working like a charm. Now it's just a matter of getting the poor boy to trust the bottle again - but I'm hoping you women have some good suggestions for that, too.

Found this on the internet. Hope it helps!

Per Lawrence & Lawrence (p. 158), the amount of BSSL in a particular mother's milk does not vary during a feed, and is not different at different times of day or different stages of lactation. There is evidence that there may be a decrease in lipase activity over time in mothers who are malnourished.

What can I do if my storage problem is due to excess lipase? Once the milk becomes sour or rancid smelling/tasting, there is no known way to salvage it. However, newly expressed milk can be stored by heating the milk to a scald to inactivate the lipase and stop the process of fat digestion. Scald the milk as soon after expression as possible.

To scald milk:

* Heat milk to about 180 F (82 C), or until you see little bubbles around the edge of the pan (not to a full, rolling boil).
* Quickly cool and store the milk.

Scalding the milk will destroy some of the antiinfective properties of the milk and may lower some nutrient levels, but this is not likely to be an issue unless all of the milk that baby is receiving has been heat-treated.

I think that's what my sister had and her solution was to pump now and refridge as soon as possible for as short as possible and then scald when she got home. It's not perfect, but I think that's what she did. Microwaving breastmilk does change it's composition so I wouldn't do that under any circumstances.

I have the same problem, and this is what I do:

Use a Munchkin bottle warmer and fill the water container twice and add it to the warmer. Loosen the bottle cover and put the freshly pumped milk in the warmer, and put the sterilizing cap on the warmer so the heart stays in. Start the warmer and once it has completed warming, put immediately into your bottle cooler. This heats up the milk to the proper temperature so that the enzyme is inactive, and preserved the taste of the milk. Otherwise, the milk tastes and smells like cheese. The milk can be frozen at this point and it will still be fine when you defrost it. I use Medela bottles, and they fit in the warmer perfectly. I keep the warmer right under my desk, and it seems to be the most convenient system for a really annoying problem. Good Luck!

If she hasn't already, it sounds like a visit with a lactation specialist would be very helpful. 1/2 an hour with one is worth about 20 hours searching online. And you get better answers.

Good luck.
