Does freezing breast milk affect antibodies?

The Impact of Freezing on Antibodies in Breast Milk
Breast milk is renowned for its rich nutritional profile and its vital role in providing infants with essential antibodies that bolster their immune systems. However, many parents and caregivers wonder whether the process of freezing breast milk affects these crucial antibodies.
Understanding Antibodies in Breast Milk
Breast milk contains a variety of immunological components, including antibodies, which are critical for protecting infants from infections. These antibodies, particularly immunoglobulin A (IgA), are transferred from the mother to the baby, offering a protective shield against pathogens during the early months of life. The dynamic nature of breast milk means that its composition can change based on the infant’s needs, making it a tailored source of nutrition and immunity.
Freezing Breast Milk: What Happens?
Freezing breast milk is a common practice for mothers who wish to store milk for later use. The recommended storage temperature is below -20°C, which is effective for preserving the milk’s nutritional quality. However, the question remains: does freezing compromise the antibodies present in the milk?
Research indicates that while freezing breast milk can lead to some degradation of its components, the impact on antibodies is less severe than one might expect. A study highlighted that freezing does not completely eliminate the presence of antibodies; rather, it may reduce their levels slightly over time. This means that even after being frozen, breast milk still retains a significant amount of its immunological benefits.
The Balance of Benefits and Risks
While freezing breast milk is a practical solution for many mothers, it is essential to understand that the quality of the milk can deteriorate over extended periods. The longer the milk is stored, the more likely it is that some of the bioactive factors, including antibodies, may diminish. However, even with this potential reduction, frozen breast milk remains a valuable resource for infants, particularly when fresh milk is not available.
Moreover, specific studies have shown that freezing breast milk does not prevent the transmission of certain viruses, such as cytomegalovirus (CMV), indicating that the freezing process does not entirely negate the protective qualities of the milk. This suggests that while some antibodies may be affected, the overall immune support provided by frozen breast milk is still significant.
Conclusion: A Practical Approach
In conclusion, freezing breast milk does have some impact on the antibodies it contains, but it does not render the milk devoid of its immunological benefits. For mothers looking to store breast milk, it remains a viable option, especially when considering the convenience and necessity of having milk available for feeding. While fresh milk is always preferable, frozen breast milk continues to offer essential nutrients and antibodies that support an infant’s health. Thus, parents can feel reassured that even after freezing, breast milk retains much of its protective power, making it a worthwhile choice for infant feeding.

When is breast milk most nutritious?

Four weeks onwards: Mature milk
By the time your baby is four weeks old, your breast milk will be fully mature. It’s rich in protein, sugar, vitamins and minerals, plus numerous bioactive components – such as hormones, growth factors, enzymes and live cells – to support your baby’s healthy growth and development.

Does freezing breastmilk affect quality?

Thawed milk is an excellent alternative when fresh breast milk isn’t available. Previously frozen breast milk has similar nutrient and antibody content to fresh milk. It does lose a small amount of those qualities but can still provide a baby with the nutrition it needs.

What are the disadvantages of frozen milk?

One common issue that arises when cow milk is frozen is its tendency to change consistency or texture. In particular, when frozen milk is brought back to liquid form, fat can separate, resulting in a graininess that some find worrisome or even off-putting.

Does freezing milk destroy nutrients?

People can freeze most milk, including breast milk or human milk. Frozen milk retains its nutritional profile when it thaws, and the sooner someone freezes it, the better the milk quality after thawing. The enzymes and fat-soluble vitamins it contains may decrease very slightly but largely remain the same.

Does frozen breast milk lose benefits?

Keep in mind that research suggests that the longer you store breast milk — whether in the refrigerator or in the freezer — the greater the loss of vitamin C in the milk. It’s also important to note that your breast milk changes to meet your baby’s needs.

Does freezing breastmilk destroy antibodies?

Remember to label the breast milk with the date that you pumped it. Thaw milk in the refrigerator or in warm water just before feeding. Thawed milk must be used within 24 hours. Note: freezing breastmilk destroys some of its antibodies.

How many ounces of breastmilk does a baby need to get antibodies?

In fact, there is some research that indicates that even as little as 50 ml of breastmilk per day may help prevent disease in breastfed babies. Additionally, our body recognizes the importance of this protection and increases the concentration of SigA as our milk supply begins to decrease.

Will the antibodies in breastmilk keep baby from getting sick?

Your baby won’t catch the illness through your breast milk – in fact, it will contain antibodies to reduce her risk of getting the same bug. “Not only is it safe, breastfeeding while sick is a good idea.

The good news: Any amount of breast milk is beneficial for your baby, whether you’re exclusively breastfeeding or supplementing with formula – and whether you’re nursing, pumping some breast milk, or exclusively pumping.

Can frozen breastmilk make a baby sick?

Certain components of frozen expressed milk may change when the milk moves from liquid to frozen and then is thawed again. There is no evidence that milk that has undergone these changes is unsafe and most babies will drink it.
