Excess Lipase In Breast Milk (Get The Facts So You Can Avoid Dangers!)

Breast milk is produced by mothers daily at the right temperature, with maximum freshness. Unfortunately, if the mother chooses to pump breast milk for storage, the milk will slowly deteriorate over time. Some mothers say that their stored breast milk has a distinct soap-like taste and odor.This is actually caused by lipase.

Here is what you need to know if you have excess lipase in breast milk.

Quick Navigation

What Is Lipase?

Lipase is an enzyme found in breast milk. It provides several beneficial functions that can help the baby digest the milk and absorb its nutrients better.

Unfortunately, lipase will also break down milk fat. This will make the milk smell, and taste soapy. It is not known if most mothers have excess lipase in their breast milk. What is known however, is that for as long as the change in taste and odor is not too strong for the baby, he or she can drink breast milk with excess lipase safely.


First of all, lipase can help keep the milk fat emulsified. This enzyme can help make the fat globules small so that the baby’s tummy can easily digest the fat content of the milk.


Secondly, lipases can also help break down milk fat, this will allow the baby to easily absorb the fatty acids, and the vitamins found in the breast milk.


Thirdly, the lipase found in breast milk is in the form of bile salt-stimulated lipase. This type of lipase is very useful against protozoan parasites. All these benefits are designed to help support the baby’s digestion, as well as to protect your child’s tummy.

What Happens If You Have Excess Lipase In Your Breast Milk?

Moms can find out that they have excess lipase in breast milk whenever their stored milk starts to smell or taste different after a few days. But this is something that you do not have to necessarily worry about. This is because the nutrition in breast milk that hs excess lipase is still intact.

What might happen however, is that the baby will reject the milk because it now has a different taste or smell. This of course, will force moms to provide fresh milk, and it will also force them to discard their reserves. This can be very frustrating as you now have to find a way to replenish the discarded quantity. There are instances when moms have to throw away milk stores that are supposed to be reserved for the next few weeks. There are also scenarios when the baby just drinks the milk simply because he or she does not mind or detect the changes in taste. You should also remember that having breast milk that smells and taste like soap, is very different to having milk that smells and tastes sour. This is because the soap-like taste and smell in your milk will mean that it has an excess in lipase, but it is still safe for the baby to drink.

On the other hand, a taste or smell that is sour in your breast milk can mean that it has excess in lipase or that it is now rancid. Just to be on the safe side, sour breast milk should not be given to your baby especially when you do not know why it has turned sour. The changes in the taste of breast milk can also be caused by the mother’s drinking water. You can opt to drink distilled water so you can avoid putting ions or minerals into the breast milk that you produce. This can also help you know if the change in taste is actually caused by minerals instead of excess lipase.
