How to Scald Breastmilk in 3 Easy Ways

Does your newly expressed breastmilk have a different taste and smell? Does it taste metallic and smell soapy? If yes, then it means that you have an excess amount of the enzyme called lipase in your breastmilk.

This enzyme is normally present in breast milk. Under normal conditions, this enzyme keeps breastmilk well- mixed, and inactivates viruses and breaks down fats to allow the baby to digest milk easily. But overproduction of this enzyme can facilitate milk spoilage at a faster rate.

While the milk, in itself, is not harmful to your baby, the change in its taste and smell may cause your baby to reject it. With that in mind, what is the best thing that you can do to make your breastmilk acceptable to your child? Many experts recommend scalding your breastmilk before storing it.

If this process is new to you, you may have no idea on how to do it. Lucky for you, I have written this article to teach struggling breastfeeding mothers how to scald breastmilk. If you want to know how, continue reading!


What You Will Need

  • Microwave
  • Stove
  • Bottle Warmer
  • ​PotIce
  • ​Water
  • ​Any container that can fit a baby bottle
  • ​Funnel
  • ​Stainless-steel baby bottle

This is recommended instead of the glass baby bottle as stainless steel can be able to withstand high temperatures without any risk of breaking.

  • Temperature gun/ Digital thermometer with alarm/ kitchen thermometer

If you plan on scalding milk via stove and microwave, the thermometer gun is highly recommended. For scalding milk via bottle warmer, the digital thermometer with alarm is the best option.

Step-by-step Guide on How to Scald Breastmilk

Here are the steps you need to take to scald your breastmilk.

Part I. Scalding the Milk

There are three ways on how to scald breastmilk - on the stove, in the microwave and in a bottle warmer. All options are convenient, so you are free to choose which one would suit your needs the best.

But if you wish to retain more nutrients and to avoid overheating the milk, the microwave technique is the best option.

If you are ready to scald your breastmilk, let’s get started!

Technique #1: How to Scald Your Breastmilk in The Stove

Step 1.  Prepare the milk.

Place a small pot over low heat on the stove. Pour your freshly expressed breastmilk into it.

Step 2. Monitor the temperature.

Keep in mind that when heated in the stove, the milk will boil at a faster rate as compared when it is heated in the bottle warmer or microwave. To avoid overheating and burning the milk, use a thermometer gun to monitor the temperature.

Pro Tip: Prevent the milk from forming at the bottom by giving it a stir every time the temperature goes up by 10-20 degrees.

Step 3. Remove pan from heat.

Once the temperature reaches 180 degrees Fahrenheit, remove the pot from the stove.

Pro Tip: One sign that the milk has already achieved such temperature is the formation of bubbles at the edge of the pot.

Technique #2: How to Scald Breastmilk in the Microwave

Step 1. Place breastmilk in the microwave.

Place 1 cup of fresh breastmilk in the microwave. Set the temperature on high and start cooking the milk for 2 minutes.

Step 2. Stir the milk.

After a minute, open the microwave and stir the milk using a spoon. Close the microwave and start heating the milk again for a minute.

Step 3. Check the temperature.

Once again, open the microwave and check the temperature of the milk using either a kitchen thermometer or a thermometer gun. If the temperature has already reached 180 degrees Fahrenheit, transfer the milk to a baby bottle.

If the temperature has not yet reached the target, continue microwaving the milk but this time, set the microwave to low temperature and continue heating. Check the milk after every 15 seconds to make sure that it will not go beyond 180 F.

Technique #3: How to Scald Breastmilk in the Bottle Warmer

Step 1. Prepare your breastmilk.

Pour your breastmilk into the stainless steel baby bottle. Place the bottle in the bottle warmer. Add water into the warmer.

Pro Tips: The amount of water you should place into the warmer must reach the same level as the milk inside the bottle. If you wish to speed up the heating process, it is recommended that you add warm tap water to the bottle warmer.

Step 2. Monitor the temperature.

Set the alarm of the thermometer to 180 degrees Fahrenheit. Even with the alarm set, it is a must that you continuously monitor the temperature.

Pro Tip: To prevent the build-up of milk at the bottom of the bottle., stir the milk once the temperature goes up by 10 degrees.

Step 3. Remove bottle from the warmer.

Once the alarm of the thermometer goes off, turn off the warmer and remove the bottle.

Part II. Cooling the Milk

After the scalding process, transfer the milk from the pot or cup to a stainless steel baby bottle. If you have decided to employ the 3rd technique, remove the baby bottle from the warmer.

Pro Tip: Use a funnel in transferring milk from pot or cup to the baby bottle to avoid spillage.

Afterwards, place the baby bottle in an ice bath. You can prepare the ice bath by getting a container (where the bottle can fit in) and filling it with ice and water. Let the milk cool down for a few minutes.

Part III. Storing the Milk

Once the milk has cooled down, store them following the standard storing procedure. You can place the bottle in the refrigerator where it can last for 5-8 days. If you want it to last longer, you can place it in a freezer bag and freeze.

Lipase is an enzyme that is commonly found in breastmilk. However, there are some mothers who produce too much of this enzyme which causes the milk to spoil at a faster rate. As a result, your breastmilk (even if freshly expressed) will have a metallic taste and soapy smell.

While excess lipase is not harmful to your baby, the change in smell and taste may cause your baby to reject the milk. To address this issue, scalding the milk is highly recommended.

We have provided a comprehensive guide on how to scald breastmilk in three different ways. Just choose which option you wish to use and follow the directions, and you can reverse the change in smell and taste of your breast milk.
