Have you noticed white spots on frozen breast milk? 

The term “frozen milk” may sound familiar to women who store their breastmilk.

Whether you are a working woman or a housewife running errands, storing the breastmilk will help feed your baby even in your absence.

When your baby’s caretaker feeds him your stored breastmilk, it’ll help ease the separation.

As a result, your kid will benefit from breast milk even if you are not around.

There are two ways to store breast milk: use it straight away or freeze it.

Whatever method you pick, there are a few things to keep in mind to make your baby’s milk safer and healthier.

Following are the guidelines to understand the storing of fresh breast milk.

White Spots On Frozen Breast Milk

When breast milk is frozen, the milk component separates from the cream component n the breastmilk.

When fat is present in frozen milk, a white spot may appear. When the fat separates at the top of the container, a white spot appears.

When milk stored in bags is initially frozen laying flat, white spots will form on the front face of the bag. 

After the milk has thawed, stir gently to combine the components again.  Breast milk contains natural lipase.

A digestive enzyme helps break down milk into smaller components to make them more easily digestible for your baby and combat disease-causing organisms. 

The breakdown of milk fat occurs faster in some women because of excess lipase production.

When this occurs, breast milk can sometimes smell or taste different.

Occasionally, people have reported having a soapy or sour taste in the milk.

Hence, after pumping, scald the milk so that the milk doesn’t change after being thawed. 

Scalding the breastmilk prevents different smells and flavors from developing since lipase is reversed.

Following pumping, breast milk naturally separates into fat and water, with fat rising to the top and water sinking to the bottom.

A gentle swirl will easily mix milk and keep it in good condition. 

1. How To Scald Breast Milk?

In this simple process, excess lipase is removed from breast milk, so it does not change its smell or taste once stored. 

Heat the milk on the stove as soon as possible after pumping until you see tiny bubbles starting to form around the pan’s rim.

Refrigerate the milk as quickly as possible. Once completely cooled, store in a freezer-safe container.

2. Separation Of Breast Milk

With cooler temperatures, breast milk begins to separate in storage bottles or bags, with Breasts rising to the top and milk with more water-based components sinking.

Both are typical, just as the oil separates from water when dressing salad.

The components should be milked together before feeding by gently swirling the container for a few minutes to blend the milk. 

3. Tips For Storing Breast Milk Properly

The following guidelines can help you store your breast milk correctly:

Storage bags 

When storing expressed breast milk, use storage bags or clean food-grade containers with tight-fitting lids made of glass or plastic.

You should only use BPA-free plastic bags if you are using plastic bags.

You should not store breast milk in non-designated disposable bottle liners or plastic bags.

Time Spent In Storage

Freshly expressed or pumped milk can be stored in the refrigerator for up to four days, in the freezer for six months, or at room temperature for four hours.

Keeping food frozen indefinitely will keep it safe, but above-recommended storage times are critical.

Details On The Storage

You should label the breast milk with the date you expressed it. Breast milk should not be kept in the refrigerator or freezer door.

You should freeze breast milk in quantities of 2-4 ounces at a time (or according to how much will be offered at each feeding); follow the proper storage guidelines to avoid wasting breast milk.

Signs Your Breast Milk Has Gone Sore

It is easy to prevent milk from spoiling by following these recommendations.

There are, however, a few ways to tell whether breast milk is spoiled if you lose track of time (which is common among new moms).

Foul Smell

A foul odor in breast milk indicates spoiled milk. In these cases, it will smell like rotten milk – the kind that makes you gag if it’s anywhere near your nose.

When Stirred, It Does Not Mix

Despite swirling your breast milk around to re-constitute it, if your breast milk still has chunks remaining in it, then verify whether your milk has spoiled.

Milk can’t always be judged by the look, the smell, or taste.

So to ensure the safety of your milk, make sure you adhere as closely as possible to the recommended storage guidelines.

It Was Stored For More Than 4 Days

The label should be attached to breast milk that is pumped.

You shouldn’t use breast milk that’s been in your refrigerator for more than four days.

If you want your milk to last the longest, place it in the center of your fridge, not alongside the door, where it gets the most fluctuating temperatures.

It Was Improperly Stored

Keep your breast milk in a cool, dry place and follow the storage guidelines described above to keep it as fresh as possible.

You should cool the milk in the fridge or a cooler bag as quickly as possible after pumping since many moms pump at work or elsewhere away from home.

Freeze the milk as soon as you get home.

Tastes Sour

You can taste your milk to determine if it is sour.

Although, remember that you may still experience a taste of “off” to your breast milk due to the enzymes breaking down. Use topically if in doubt.

Parenting journeys for new mothers can be no less than a roller coaster ride; their burnout is real.

Breast milk is great, apart from all the vitamins minerals, not to mention the antibodies it can give to the babies.

And it’s free! Moms can healthily feed little ones freshly pumped milk directly, but storing it is different. 

Frequently Asked Questions

Does Frozen Breast Milk Contain Bacteria?

As soon as you freeze milk for the first time, antibodies and vitamins break down. Bacteria can grow.

Hence, you should freeze milk only once.

Is It Okay For Frozen Breast Milk To Have Air Bubbles?

You should avoid air bubbles in frozen breast milk as much as possible. Excess air can cause breast milk to turn black.

Your baby’s tummy may be upset by air bubbles in the defrosted milk, causing excessive gassiness and even colic after defrosting breastmilk.

When Defrosting Frozen Milk, What Should You Do?

Defrosting milk in the refrigerator is the safest method. However, this method takes several hours; this is not ideal if you want to have a cup of tea right away!

After the milk has thawed in the fridge, place the container into the freezer until it is liquid again.
