How to Store Powdered Milk for Long Term

It’s critical to preserve your milk in the best possible conditions to ensure that it stays fresh. Milk is more expensive than fuel in many areas of the world.

Therefore it’s vital to keep it properly. Milk may be stored properly to extend its shelf life, improve freshness, and save money.

Milk is a common component in many recipes as well as a popular beverage. If you don’t have access to a gallon of milk, powdered milk is a convenient, easy-to-use alternative. 

As a result, you must incorporate it in your food storage preparations. Powdered milk, on the other hand, requires adequate storage to retain its quality.

In this article, we will focus on how to store powdered milk. So, read it to learn about this hot topic

Why You Need To Store Powdered Milk Properly

Why You Need To Store Powdered Milk Properly

As per the USDA, powdered milk may be stored indefinitely as long as it is kept dry and at a temperature below 75 degrees Fahrenheit

Because powdered milk is susceptible to oxidation, which can result in an unpleasant off-flavor in higher temperatures, rotate goods every six months.

Powdered milk is among the most susceptible to changes in the environment, notably temp and water absorption.

Vitamins A and D are also photosensitive, which means they deteriorate quickly when introduced to sunlight. The storage space for dried milk should be maintained as cold as feasible.

If feasible, store them in the freezer or in a thoroughly air-conditioned area to increase the shelf life of the nutrients.

If the storage container is translucent or transparent, place the milk in a second container that is opaque to light and must be kept in the darkroom.

Because dry milk absorbs moisture and smells from the air, storage containers should be air and moisture impermeable.

It will last longer if it is kept as dry as possible.

Desiccants, on the other hand, are a wonderful concept. The presence of oxygen might hasten the breakdown process.

To replace oxygen-rich air, powdered milk can be packed with nitrogen or carbon dioxide.

Oxygen absorbers or vacuum canning can also reduce the amount of oxygen accessible. 

If the dry milk you bought wasn’t packed for long-term storage, you should immediately repackage it.

How Long Does Powdered Milk Really Last? or Shelf Life Of Powdered Milk

How Long Does Powdered Milk Really Last? or Shelf Life Of Powdered Milk

Powdered milk has a different shelf life depending on the kind. Because fat is less stable than nonfat powdered milk, it lasts longer than powdered whole milk or buttermilk.

Normally, it takes 18 months. Powdered milk can be stored forever, according to the United States Department of Agriculture (USDA); 

However, the shelf-life does not rely on the kind of powdered milk. On the other hand, nonfat powdered milk can last longer than powdered whole milk or buttermilk since fat is less stable.

As a result, for long-term food preservation, nonfat dried milk is preferable. If you look at the “best by” date on the package of powdered milk, you should use it up quickly.

How to Store To Maximize Powdered Milk Shelf Life

Powdered milk might go rancid in as short as 30 days if not stored correctly, but the shelf life can be prolonged if maintained properly.

Emphasize whatever approach you’re using: Store in a cold, dark, and dry location at all times.

Mylar bags are metallic-looking pockets that, when entirely sealed, may be air and moisture impervious.

To keep dried milk in Mylar bags, add a desiccant to the bottom of the pouch and an air absorbent to the top before closing. 

The moisture is controlled by the desiccant, while the oxygen is removed by the oxygen absorber. 

Powdered milk can survive for 15 years if kept in a cool area. Some firms can even claim a 25-year shelf life.

Keep It In Original Plastic Or Paper Packaging

Some Powdered milk comes in pouches made of plastic or paper. When stored in this packaging, the shelf life fluctuates greatly. 

At high temperatures, dried milk deteriorated in just one month, according to one research. 

Dried milk can survive up to a year if stored in a cold, dark, and dry environment, but I wouldn’t take the chance. Instead, choose a more dependable storing mechanism.

Not highly recommended 

When stored in this sort of packaging, the shelf life dramatically decreases.

Keep Them In The Refrigerator Or Freezer

The shelf life of dried milk can be extended by lowering the temperature. Powdered milk can acquire unpleasant flavors in as little as six months when stored at temperatures around 90 degrees Fahrenheit.

The milk will grow sour after a month at 104F.  Powdered milk, on the other side, may be kept for up to four years at temperatures as low as 50 degrees Fahrenheit.

It’s preferable to keep it cool when storing it. The flavor was best kept at 50 F/10 C, but those held at 90 F/32 C developed off-flavors after just six months and tasted terrible after two years.


Powdered milk that has been canned with carbon dioxide or nitrogen instead of air (which includes oxygen) will last longer. 

The amount of oxygen accessible is also reduced via vacuum canning or oxygen absorbers. Vacuum sealing and then storing in a dark place may be the best method.

If you don’t have a vacuum sealer, one-gallon zipped freezer bags, and oxygen absorbers will suffice.

Use Mylar Bag

Mylar packs are metallic-looking bags that, when entirely sealed, may be air and moisture impervious. 

Dry essentials, such as powdered milk are thought to be the greatest long-term storage option.

To keep dried milk in Mylar bags, place a desiccant at the bottom of the bag and an oxygen absorbent at the top before covering the package.

The moisture is controlled by the desiccant, while the oxygen is removed by the oxygen absorber. 

Powdered milk can survive for 15 years if kept in a cool area. Some firms can even claim a 25-year shelf life.

Metal Pouches (Not Mylar)

Many powdered milk manufacturers use metal pouches for packaging their goods. Unlike plastic or paper pouches, these pouches keep milk fresh for far longer.

They block light while also preventing moisture from entering the milk. These items typically have a shelf life of one to two years.

Those metal bags, however, still contain oxygen, and the seams frequently leak. You’ll still need to keep the milk in a cold, dark, and dry place. 

You should utilize the milk within a few months if possible. If required, repackage the dried milk into a more reliable storage container, such as Mylar bags.

Use Cans

Several powdered milk brands are available in #10 cans.

Nevertheless, bear in mind that not all #10 skim milk powder cans are made equal.

Some brands used nitrogen flushing or oxygen absorbers to eliminate oxygen from the cans.

The ones that are nitrogen-packaged are more successful and have higher nutritional levels.

Choose a trustworthy brand that reveals the procedures it uses for product packaging. Canned dry milk, on the other hand, may survive up to five years if stored in a cold place.

Use Canning Jars With Oxygen Absorbers

Small quantities of powdered milk can be stored in the container.

To regulate moisture levels, some individuals use a desiccant in the jar. Despite the presence of air in the jar, the milk might grow stale in 3 to 12 months.

Get oxygen absorber packets to extend the shelf life.

Absorber packets are little iron-based packets that absorb oxygen from the air. Remove virtually all oxygen from the container if you place one in a canning jar.

The lid will appear sucked down, indicating that the oxygen absorbers are operating.

Regardless, the jar must be stored in a cold, dark location. Due to the lack of oxygen, dried milk can survive up to five years.

Some Tips When Storing Powdered Milk

Some Tips When Storing Powdered Milk
  • If you don’t use powdered milk very often, you might want to try freezing it. Simply scoop some out as needed. It’s not necessary to let it get to room temperature first.
  • This will preserve the freshness of your powdered milk for a long time. Keep it securely sealed between uses to avoid freezer burn.
  • It will last longer if it is still in its original packaging and has not been opened.
  • Use desiccants to keep moisture at bay.
  • Store items in a dry, off-the-floor location to allow for air circulation.
  • Before pouring in a fresh bag of powdered milk, make sure you’ve used up the full canister. That way, over time, layers of “old” powdered milk won’t become mixed up with layers of “new” powdered milk.
  • Mark any container with the date you opened powdered milk and flavor so you know how old it is.

How To Test if Powdered Milk Has Gone Bad

If you see yellow discoloration or an unpleasant stench in your powdered milk, it’s time to throw it out.

These are indicators that the milk has gone sour. If you suspect that moisture has entered the package, you may be dealing with mold and bacteria development.

Label powdered milk with the “best by” date and the date you moved it if you transfer it from its original container.

Consider vacuum-packing and storing the remaining dried milk if you won’t use it within three months.

Keep nonfat dried milk refrigerated and consume it within five days of reconstituting it.

Is Powdered Milk A Viable Substitute For Real Milk?

Is Powdered Milk A Viable Substitute For Real Milk?

Here’s everything you need to understand regarding the health benefits of milk powder. A dairy product created by evaporating normal milk is powdered milk. 

Because milk has such a short shelf life, it is especially useful for individuals who do not have access to fresh milk on a daily basis. 

The cost of transportation is also reduced by reducing it to powder. This milk may last a long time if kept in an airtight container, and just a teaspoon can transform your tea, coffee, or shake. 

Despite the fact that it is primarily skimmed milk powder, it adds a smoothness to your food and beverages that some people prefer over ordinary milk.

Milk powder is primarily used in baby milk, but it is also used to produce sweets, chocolates, and Indian mithais such as Gulab Jamun and Cham cham. 

Many individuals choose milk powder over normal milk since it is considered to be a healthier alternative.

Fun Facts

Although it has nothing to do with how to preserve milk powder, if you want to test a new flavor when producing powdered milk, do this:

Add a little sugar and a dash of vanilla to your powdered milk. If you serve it cold with sugar and vanilla, you will notice a significant improvement in flavor.

Blend milk powder with finely broken ice, a pinch of brown sugar, and agar. I tried the same thing with cocoa powder ten years ago. 

That meal is now well-known and well-liked. Powdered milk, I believe, will become fashionable at some point.


Powdered milk’s shelf life is greatly influenced by its storage conditions. Goods kept in cardboard or packaging applications in a hot, damp climate may have a shelf life of only a few months.

Dried milk will deteriorate in 30 days if the temperature rises over 104 degrees Fahrenheit. Dried milk, on the other hand, may survive up to 15 years if stored properly.

Dried non-fat milk lasts significantly longer than full-fat milk. The reason for this is that fats and oils are extremely heat and oxidation-sensitive. 

They will begin to grow rancid, giving the milk a foul, sour odor and flavor. Long-term preservation of full-fat milk is typically not recommended.

Except for the method of keeping powdered milk in the refrigerator or freezer, the other preservation methods can be used even if you want to live off the grid.
