HELP!!

in June 2014 Moms
Sorry I haven't been on for a while so I have no idea if anyone has discussed this but does anyone know if there's anything I can do to salvage frozen milk that has a lot of lipase? I had no idea about this until tonight when I broke into my freezer stash for the first time. After thawing my milk I smelled it and it smelled a tad bit soapy.. so I tasted it and it also tasted soapy. I gave some to my 1 year old because we're out of regular milk and he asked for a bed time bottle and he rejected it.. someone tell me my stash isn't ruined!! I have about 200 oz and im crying over the thought that it all might be wasted :(

    I did a quick search on KellyMom.com (being that I don't know anything about this): https://kellymom.com/bf/pumpingmoms/milkstorage/lipase-expressedmilk/

    Does your milk smell or taste soapy?

    A few mothers find that their refrigerated or frozen milk begins to smell or taste soapy, even though all storage guidelines have been followed closely. Per Lawrence & Lawrence (p. 781), the speculation is that these mothers have an excess of the enzyme lipase in their milk, which begins to break down the milk fat soon after the milk is expressed. Most babies do not mind a mild change in taste, and the milk is not harmful, but the stronger the taste the more likely that baby will reject it.

    Lipase is an enzyme that is normally present in human milk and has several known beneficial functions:

    • Lipases help keep milk fat well-mixed (emulsified) with the “whey” portion of the milk, and also keep the fat globules small so that they are easily digestible (Lawrence & Lawrence, p. 156).
    • Lipases also help to break down fats in the milk, so that fat soluble nutrients (vitamins A & D, for example) and free fatty acids (which help to protect baby from illness) are easily available to baby (Lawrence & Lawrence, p. 156).
    • The primary lipase in human milk, bile salt-stimulated lipase (BSSL), “has been found to be the major factor inactivating protozoans” (Lawrence & Lawrence, p. 203).

    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.

    Many mothers who need to store their expressed milk but have problems with excess lipase sometimes wonder whether changing their diets may help. This post to the LLLI forums discusses some ideas from human milk researcher Leon Mitoulas about this question:  Can diet changes help with the Lipase issue?

    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.

    Per Lawrence & Lawrence, bile salt-stimulated lipase can also be destroyed by heating the milk at 144.5 F (62.5 C) for one minute (p. 205), or at 163 F (72 C) for up to 15 seconds (p. 771).

    You can always see if your baby will drink it - doesn't seem to be anything wrong with the milk.

    Try mixing it half and half with fresh milk to see if that dulls the taste enough for them to drink it.

    @nunzchucks‌ he's had breast milk before but only freshly pumped milk. He steals his little brothers unfinished bottles all the time.

    @chickpea12‌ I found that same page too... I only saw info on how to fix it BEFORE freezing it.. not what to do AFTER its been frozen.

    I'm probably just going to throw it all out. I tried a fresher bag that I froze last night and it tasted worse... almost like it was bad. Ugh this sucks.

    @shiggybop‌ I just tried another bag that I froze last night and it tasted worse.. so now I'm wondering if my freezer cold enough either. I don't even know what to do because I don't want to end up giving them milk that might also be bad.

    But it sounds like you don't need to throw it out. It's safe. Just see what LO does.





    I'm not new. I just hate The Bump.

    I'm pretty sure it has nothing to do with your freezer. It's not that the milk is bad, it's fine. Your baby may or may not like it. I had that problem and my daughter wouldn't drink it. I gave it to my friend and her son didn't mind the taste.
