Thread: Help Lipase or not??

    Default Help Lipase or not??

    I am exclusively pumping for my 2nd son. With my 1st son I exclusively breast fed so I never had to deal with the Lipase issue. My milk smells and tastes sweet and fine when it is fresh, but if it's been in the fridge for more than 24 hours or frozen and thawed it has a very strong vitamin smell and taste. Is this normal? Also I take it you have to scald it to get the lipase taste to go away?????? Does scald mean to bring it just before a boil???? Please help!

    The lipase problem is when your own milk contains enough of the lipase enzyme to begin digestion of the milk. Cool huh, for a baby who is on the breast we supply the initial enzyme to get digestion going. but who would want that in milk that needs to be stored? no one. so while the millk is still fresh bring it to just under boil. you will see it shimmer. then allow it to cool and then store it.
    If you do produce an oversupply of lipase the milk gets a smelly soapy film or crust. its gross but normal but you don't really want to give it to the baby, so just heat and store you will be fine.

    So scalding it after it's been frozen won't work
    I have at least 2.5 months worth of frozen milk that I think is ruined from lipase!!!! I've read that there is no known method other than scalding before you freeze! ahhhhhhhh

    I'm dealing with that right now too. It sucks that everything I've stored is most likely bad. I do plan to thaw some of the frozen, one bag at a time and taste it to see if it's good or not. I don't know how long my frozen milk takes to taste icky, but the refrigerated goes icky at about 24 hours. Good luck! Do read the sticky thread. It took me two days to read it all, but it was soooo helpful!
