How do I know if my breastmilk is freezer burnt?

Answered by Tom Adger

As a parent who has experienced freezer burn on breast milk, I know how concerning it can be to see ice crystals and notice a strange smell coming from your frozen milk. Freezer burn occurs when the moisture in the milk evaporates, leaving behind ice crystals and causing changes in the quality and taste of the milk.

Here are some signs that your breast milk may be freezer burnt:

1. Ice crystals: When you see ice crystals forming on the surface or inside the milk, it is a clear indication of freezer burn. These crystals can be seen as a powdery or frost-like substance.

2. Change in texture: Freezer burnt milk may appear clumpy or grainy when thawed. The texture may not be smooth and creamy like fresh milk.

3. Strange smell: If your breast milk has a sour or rancid smell, it could be a sign of freezer burn. The odor can be quite distinct and unpleasant.

4. Discoloration: Freezer burnt milk may have a yellowish or brownish tint to it. This discoloration is another indication that the milk has been affected by freezer burn.

It is important to note that freezer burn does not make the milk unsafe to consume, but it can affect the taste and quality. If you notice any of these signs, it is advisable to use the milk within a shorter time frame to ensure the best quality for your baby.

To prevent freezer burn and maintain the quality of your breast milk, here are some tips:

1. Use proper storage containers: Use BPA-free, airtight containers specifically designed for storing breast milk. Avoid using regular plastic bags, as they are more prone to freezer burn.

2. Label and date your milk: Always label each container with the date and time of pumping. This will help you keep track of the freshness of the milk and use it in the right order.

3. Store milk in small portions: Freezing breast milk in smaller quantities reduces the chances of freezer burn. Smaller portions thaw faster and are consumed more quickly, minimizing the time spent in the freezer.

4. Store milk at the back of the freezer: Keep your breast milk towards the back of the freezer, where the temperature is more consistent. Avoid storing it in the door or near the front, where temperature fluctuations are more likely to occur.

5. Use the oldest milk first: Always use the oldest milk first to ensure freshness. Rotate your milk supply to avoid any milk being stored for too long.

By following these guidelines, you can minimize the risk of freezer burn and ensure the best quality breast milk for your baby. If you are unsure about the safety or quality of your frozen milk, it is always best to consult with a lactation consultant or healthcare professional.
