Breast Pump, Does your stored breast milk have a soapy or metallic taste or smell? This could be a sign of a high slipcase. Slipcase is an enzyme that naturally occurs in breast milk, but some women can have an excess of slipcase, which can make their stored milk smell/taste off.
As the breast milk sits in cool temperatures (fridge or freezer), the slipcase starts to break down the fat in the milk. The longer it sits, the more you may start to notice the soapy or metallic smell/taste.
Having a high slipcase is not dangerous and the breast milk is still perfectly fine for the baby to drink Breast Pump but many babies will reject this milk because they don’t like the taste. Nothing is worse than finding this out when you have a freezer full of stored milk!!! So what can you do?
1. Do a slipcase test on your stored breast milk! The sooner you do this the better!
Thaw a frozen bag of breast milk to see if it has a soapy or metallic smell/taste. Try feeding it to baby and see if they drink it.
2. If your breast milk does have a high slipcase, you can scald your milk before freezing or storing it to prevent this from happening! Here’s how you do it:
-After expressing your milk, put it in a saucepan over medium heat
-Heat until it reaches 180 F, you’ll see little bubbles around the edge of the milk in the pan (do not boil!).
-Once you reach this temp, remove the milk from the heat, cool, and store as quickly as possible
3. Do you have a large stash of high-slipcase milk that baby won’t drink? You can try mixing the frozen milk with freshly pumped milk to see if they will drink it. If they absolutely refuse the milk, you can donate it to a milk bank, like Austin Milk Bank!
