Let's Talk Lipase For A Minute...

If you've been following my posts, I have thrown out several hundred ounces of frozen bm (luckily, Ryan is almost totally reverse cycling and is almost 9 mo and eating solids while I'm at work.)

I don't personally have any experience, but I did some quick research for you.


According to kellymom, it doesn't appear that once the milk is frozen scalding will reverse the lipase problem. It seems like lipase breaks down the fat from the beginning of the freezing process and once it begins, scalding will not salvage it. (sorry)

and it *SEEMS* (i'm just taking an educated guess based off of what I've read) that the concern is going beyond a scald into a full blown boil will kill of more nutrients in the milk and more of the beneficial ingredients. Scalding kills off some of them as well, but you want to lose as little of the health benefit as possible.


Is he not drinking the bottles of refrigerated milk because of lipase? Apparently it can occur in the fridge as well. I might consider seeing if he'd take scalded refrigerated milk more readily than the unscalded milk, and then make my decision on how often/much to scald after that!


Best of luck, keep us posted!

When I've frozen after scalding, the longest I've tried was about 6 weeks- and it was fine. Theoretically, it should be fine to freeze. Scalding de-activates the lipase, freezing does not. So the going bad while frozen (when not scalded)

I figured you wouldn't be concerned about the slight loss of nutrients =) LOL It still beats chemicals that you can't pronounce!! From what I read, the only time the nutrient loss would be a concern was if you were exclusively pumping. and with your little reverse cycler, he's still getting the bulk of his calories from you.


I did read in another post here, that another mom only scalds her friday stuff, so it keeps until monday. Everything she pumps during the day she leaves for the next day.

while making hot chocolate on the stove last night i finally figure out what the problem with boiling is!!!!


It is a very short point from milk boiling to milk curdling.. (my husband used to be a chef) and I'm pretty sure that would be the same with human milk as well.


So it would be VERY hard to prevent the milk from curdling if it were boiled.
