There's nothing worse than spending so much time pumping your breast milk only to find out that it's gone bad sooner than you expected. The stuff is called liquid gold for a reason, and no mom wants to have to throw out even a drop of her hard-won milk. Luckily, getting to know a few of the signs your breast milk has gone bad will save you from the pain of having to pump your milk and dump it a few days later. Not unlike cow's milk, breast milk will spoil if left out in the open, or even in the refrigerator for longer than it should be. According to La Leche League International, breast milk should be left at room temperature for no longer than four to six hours. Similarly, they stated that it should be refrigerated for no more than eight days absolute maximum, the ideal amount is 72 hours.
My expressed breastmilk doesn’t smell fresh. What can I do?
Why does my frozen breast milk smell bad?
Nothing is more disheartening than tossing out breast milk, no matter how large or small the quantity. A small number of mothers find that their expressed breast milk smells and even tastes bad after refrigeration or thawing, even if they follow proper milk collection and storage guidelines. In these cases, mothers typically describe the milk as having a sour, metallic, or soapy taste. In the absence of other causes, it is usually assumed that lipase is the culprit. Lipase is an important enzyme found in human milk. Lipase breaks down the milk fats into small particles that babies can easily digest. Laboratory testing is the only way to confirm the level of lipase in human milk.
What Causes Sour Smell Under Breast & Treatments, Tips to Get Rid of it
Breastmilk has quite a reputation for being some of the sweetest stuff on earth, especially when compared to formula. If moms have gotten a whiff or even a taste of both, then they'll know that they are drastically different. While most mothers never have to think twice about how their baby's milk might smell or taste, others struggle with rancid and even soapy scents in their infants' meals. All sorts of things can make a mother's milk turn bad.
However, for a small group of people, this boon comes with an extra challenge: changes in the aroma and possibly the taste of their milk after it has been stored for a while. Accompanying these changes are concerns that the milk is no longer good for the baby. There are several possibilities for the cause of odor or taste changes in human milk. Solutions depend on the root cause. The first step to finding a solution is to determine whether expression, handling and storage are the source of the issues, or whether highly active lipase or chemical oxidation are the cause.
