How to store powdered milk (aka dry milk, milk powder or dried milk) long term begins with understanding its unique properties as it requires specific methods to ensure longevity.

How Long Does Powdered Milk Last?

The average shelf life of dry milk varies depending on its storage method. On average, powdered milk can last 2-10 years or more when stored in a cool, dry place and in an airtight container. Proper containment is crucial to maintain its freshness.

To store it properly, keep it away from light in an airtight container. For long-term storage, use oxygen absorbers or a vacuum sealer to remove air and moisture.

But how do you store dried milk after opening? To store powdered milk, transfer it to an airtight container. Then store it in a cool, dry place away from light and moisture to maintain its quality and extend its shelf life up to 3 months.

Shelf Life Of Powdered Milk

The shelf life of powdered milk is determined by various factors. Generally, it’s recommended to use powdered milk within 18 months. 

Temperature control plays a key role in maintaining its quality for longer periods. So if milk is stored in a cool, dry place and away from heat, it will last long.

Also, the shelf-life of milk depends on the type of milk you have. For instance, nonfat powdered milk usually lasts longer than powdered buttermilk or whole milk because the fat is more unstable.

You can even find nonfat dry powdered milk at some survival stores with a 25-year shelf life. So if you’re looking to store dried milk for a long period, nonfat is the way to go.

If you have dried whole milk, use it up quickly after the “best by” date to get the freshest taste.

How To Store Powdered Milk for Long-Term Storage

Proper long-term storage of powdered milk can extend its shelf life and keep it fresh for future use. You may preserve its nutritional value and prevent moisture and contaminants from affecting its quality by taking the following specific measures:

Selecting the Right Storage Containers

Opt for airtight, food-grade containers like plastic buckets or glass jars with tight-fitting lids. For long term storage, use sealed mylar bags to block light, oxygen, and moisture. Storing nonfat, dried milk in mylar bags can make them last up to 15 years.

You can also use #10 cans if you want to store powdered milk in bulk. This is a great way to store dry milk because it is sealed airtight with an oxygen absorber directly from the manufacturer.

Including Oxygen Absorbers and Desiccants

Oxygen absorbers remove the oxygen from the container, which can help prevent spoilage and preserve the flavor of the powdered milk.

Desiccants, on the other hand, absorb moisture and help prevent the growth of bacteria and mold, which can also spoil the milk.

Use both in combination to ensure that your powdered milk stays fresh and usable for longer periods.

Right Storage Conditions

Store dried milk in a cool, dry, and dark place, such as a pantry, cupboard, or basement. Avoid exposing the containers to direct sunlight, as heat and light can degrade the quality of powdered milk and shorten its shelf life.

Properly Sealing the Containers

Ensuring that the storage containers are properly sealed is essential to prevent contamination and spoilage. If using mylar bags, use a heat sealer to create an airtight seal.

For buckets and jars, secure the lids tightly to keep out air, moisture, and pests. If you’re using mason jars, you can vacuum seal your mason jars by using a vacuum sealer kit along with your vacuum sealer.

Labeling and Rotating Your Powdered Milk Supply

Labeling and rotating your powdered milk supply ensures longevity and allows you to keep track of their shelf life.

Rotate your supply by using the oldest powdered milk first and replacing it with newer stock so you always have fresh powdered milk on hand.

Signs of Spoiled Powdered Milk

It’s crucial to know how to identify signs that your powdered milk has spoiled.

Signs of spoiled powdered milk are easily identifiable. A change in color, consistency, or an off smell indicates degradation and potential health risks.

Watch out for these signs before using your dried milk:

• Smells sour or rancid
  
  
  
• Yellow or has darkened in color
  
  
  
• Clumped together or moldy
  
  
  
• Has a gritty texture
  
  
  
• Tastes sour or has an off taste
  
  

If you notice any of these signs, dispose of them immediately.

Consuming spoiled powdered milk can lead to food borne illness and can be dangerous, particularly for young children, elderly individuals, and those with weakened immune systems.
