How to test for lipase in breast milk?

Understanding Lipase in Breast Milk
Lipase is an enzyme found in breast milk that plays a crucial role in the digestion of fats. While it is essential for breaking down fat molecules, some mothers may experience issues with high lipase levels in their milk, leading to changes in taste and smell that can affect their baby’s willingness to consume it. Testing for lipase in breast milk can help determine if this is a concern for breastfeeding mothers.
Why Test for Lipase?
Breastfeeding mothers often express milk for various reasons, such as returning to work or needing a break from nursing. However, some mothers notice that their stored breast milk develops a soapy or rancid taste after being frozen or refrigerated, which can lead to their baby refusing to drink it. This phenomenon is typically associated with high lipase activity in the milk.
How to Test for Lipase
Testing for lipase in breast milk can be done easily at home with a simple taste test. Here’s how to conduct the test:
1. Collect a Sample: Pump a small amount of breast milk, ideally around 1-2 ounces, into a clean container.
2. Store the Sample: Place the sample in the refrigerator for about 4-6 hours. This timeframe allows the milk to sit and develop any potential changes in taste due to lipase activity.
3. Taste Test: After the milk has been refrigerated, taste a small amount. If the milk tastes soapy or has an off flavor, it may indicate high lipase levels.
4. Further Testing: For a more definitive test, you can freeze the milk sample and then thaw it after a few days to see if the taste changes further. If the milk tastes significantly different after thawing, this could confirm high lipase activity.
Managing High Lipase Milk
If you discover that you have high lipase breast milk, there are several strategies you can employ to manage the situation:
– Scalding the Milk: One effective method is to scald the milk before storing it. Heat the milk to just below boiling (around 180°F or 82°C) and then cool it quickly before freezing. This process inactivates the lipase enzyme, preventing it from altering the milk’s taste.
– Using Fresh Milk: If possible, try to use freshly pumped milk rather than storing it for long periods. This can help ensure that your baby receives milk that tastes as intended.
– Bottle Feeding Techniques: If your baby refuses the milk, consider trying different bottle types or nipples, as sometimes the refusal can be due to the feeding method rather than the milk itself.
Conclusion
Testing for lipase in breast milk is a straightforward process that can help mothers identify potential issues with their stored milk. By understanding how to conduct the test and manage high lipase levels, breastfeeding mothers can ensure their babies receive the nourishment they need without the added concern of taste rejection.

How to know if breastmilk has high lipase?

The longer milk is kept at room temperature or even in the refrigerator before being frozen, the more lipase activity it will have. Milk that has a high level of lipase can develop a soapy smell and taste, but is not harmful to the baby.

Can old frozen breast milk make baby sick?

Some of the immune enhancing properties of breastmilk are decreased over time when milk is frozen. However, the risk of bacterial contamination of milk that has been kept in the refrigerator too long and not frozen, far outweighs the downside of freezing milk.

How to fix frozen breast milk with high lipase?

Mix the high-lipase frozen milk with freshly expressed milk: Mixing frozen and fresh breast milk can reduce the lipase activity in the thawed frozen breast milk and minimize the development of any unwanted tastes or smells.

How do you tell if frozen breast milk is spoiled?

Digestive enzymes and other components of breastmilk remain active even when milk is expressed or pumped. Expressed human milk may undergo odor changes when stored. Parents sometimes describe expressed or defrosted milk as smelling odd – metallic, soapy, or even rancid.

What are the symptoms of high lipase? Symptoms depend on what’s causing your high lipase.
