Your baby might refuse thawed breast milk for a few reasons, but a common culprit is lipase activity. Lipase is an enzyme that helps in the digestion of fat. However, when breast milk is frozen, lipase can cause the milk to take on a soapy or off taste upon thawing. To prevent this, try scalding the milk (heating it just before it boils) before freezing, which deactivates the lipase. If the issue persists, consider smelling or tasting the milk yourself to identify any off-putting changes and adjust your storage method accordingly.

FAQs & Answers

  1. What causes breast milk to have a soapy taste after thawing? Lipase, an enzyme in breast milk, breaks down fat during freezing and thawing which can cause the milk to develop a soapy or off taste that some babies may reject.
  2. How can I prevent my breast milk from tasting off after freezing? Scalding the breast milk by heating it just before boiling before freezing deactivates lipase and helps prevent the milk from developing a soapy taste after thawing.
  3. Is it safe to feed my baby breast milk that smells or tastes off? If breast milk smells or tastes off, it may not be safe for your baby. Always check the milk before feeding and discard any that seems spoiled or has an unusual odor.
  4. How should I store breast milk to maintain its quality? Store breast milk in clean, airtight containers and freeze promptly. Thaw in the refrigerator or warm water, and avoid repeated freezing and thawing to preserve its quality.
