High Lipase Milk
Some moms may notice that their expressed breast milk has a soapy or metallic smell and taste. This is often due to high lipase activity in the milk. This guide provides information on what high lipase milk is, its effects, and how to address it.
What is Lipase?
Lipase is an enzyme naturally present in breast milk. It plays a crucial role in breaking down fats making the milk easier for your baby to digest. Lipase helps keep the fat mixed with the whey portion (liquid part) of the milk, ensuring your baby receives essential nutrients.1
What Causes High Lipase Milk?
High lipase activity in breast milk can cause the milk to develop a soapy or metallic taste and smell when stored. This change occurs because the enzyme breaks down the fats in the milk more quickly, releasing fatty acids that alter the milk’s flavor. The exact cause of high lipase levels in some mothers’ milk is not well understood, but it is a natural variation and not harmful to your baby.1
The primary effect of high lipase milk is the change in taste and smell. While this does not make the milk unsafe for your baby, some infants may refuse to drink stored milk with an altered flavor. It is important to note that high lipase milk is still nutritious and beneficial for your baby.1
Managing High Lipase Milk
If you suspect that you have high lipase milk, here are a few things you can try:
- Storing Milk
- Make sure that you are storing your milk according to recommendations.2,3 The longer milk is frozen, the greater the potential for changes in smell or taste. Colder temperatures may slow changes in expressed breastmilk. Always store breastmilk in the coldest part of your freezer.2,3
- Using Fresh Milk
- If your baby refuses stored milk with high lipase, try to use fresh milk whenever possible. Freshly expressed milk typically does not have the altered taste and smell.1
- Mixing Milk
- If you need to use stored milk, try mixing it with freshly expressed milk to dilute the soapy or metallic taste. This can make the milk taste better for your baby.1
- Consulting a Lactation Consultant
- A lactation consultant can provide personalized support and guidance. They can help you develop strategies to manage high lipase milk and ensure that your baby receives adequate nutrition.
