Some women have a higher level of the enzyme lipase in their breastmilk. Lipase breaks down fat in the breastmilk, making it easier for babies to digest.
However, sometimes high levels of lipase can interfere with the storage of expressed milk, because lipase starts breaking down the fat in the milk when it is refrigerated or frozen. When this happens, the milk may take on a bad odor, and it also may have the same bad taste. The milk itself is ok for baby to drink, but it's a matter of whether it's palatable for baby.
These links have more information about lipase and how it can affect milk that is refrigerated or frozen:

Each mom is different. For some the expressed milk is fine in the refrigerator for several days before it starts to react, but for others it may happen right away in the refrigerator or freezer.
One option for expressed milk already frozen is to mix it with freshly expressed milk before giving it to baby to see if that makes it more appealing.
To pump and store expressed milk in the future, try some experiments to find out what works best for you. You may find, for example, that you can refrigerate your milk for 2 days just fine, but that if it's not used within 2 days, you should scald it and then freeze it.
When scalding, pour the milk in a pan and put it on medium heat. Watch it closely and remove it from the heat as soon as you see little bubbles forming around the edges, but before boiling. Then cool slightly and freeze as usual.
