With the rise of plant-based diets and the increasing popularity of non-dairy milk alternatives, oat milk has become a staple in many households. However, one of the biggest concerns about oat milk is its shelf life. Unlike cow’s milk, oat milk is more prone to spoilage and has a shorter shelf life, which can be a major drawback for consumers. But fear not! With a few simple tips and tricks, you can increase the shelf life of oat milk and enjoy it for a longer period.
The Science Behind Oat Milk’s Shelf Life
Before we dive into the ways to increase the shelf life of oat milk, let’s first understand why it spoils so quickly. Oat milk is made by soaking oats in water and blending them with water, which creates a nutrient-rich liquid. However, this process also creates an ideal environment for bacteria and mold to grow. Oat milk is high in carbohydrates and has a neutral pH level, making it an ideal breeding ground for microorganisms.
Additionally, oat milk lacks the natural preservatives found in cow’s milk, such as lactoferrin, which helps to inhibit the growth of bacteria. This means that oat milk is more susceptible to spoilage, especially when stored improperly.
Why Shelf Life Matters
A longer shelf life is important for several reasons. Firstly, it reduces food waste and saves consumers money. Oat milk can be expensive, and having to discard a spoiled batch can be frustrating and costly. Secondly, a longer shelf life allows consumers to stock up on their favorite brand or flavor, reducing the need for frequent trips to the store. Finally, a longer shelf life can also reduce the carbon footprint of oat milk production, as less energy is wasted on producing and transporting spoiled batches.
Storage Tips for Longer Shelf Life
Now that we understand the science behind oat milk’s shelf life, let’s explore some storage tips to increase its shelf life.
Refrigeration
The most important thing you can do to increase the shelf life of oat milk is to store it in the refrigerator at a temperature below 40°F (4°C). This will slow down the growth of bacteria and mold. Make sure to check the expiration date on the package and consume it within 7-10 days of opening.
Airtight Containers
Using airtight containers can help to prevent contamination and spoilage. Transfer the oat milk to an airtight container, such as a glass bottle with a tight-fitting lid, and store it in the refrigerator. This will help to prevent air from entering the container and causing the growth of microorganisms.
Freeze It!
Freezing oat milk is another way to increase its shelf life. Simply pour the oat milk into an airtight container or freezer bag and store it in the freezer. Frozen oat milk can be stored for up to 3-6 months. When you’re ready to use it, simply thaw it in the refrigerator or at room temperature.
Manufacturing Techniques for Longer Shelf Life
While storage tips can help to increase the shelf life of oat milk, manufacturers can also play a crucial role in extending its shelf life.
Ultra-High Temperature (UHT) Processing
UHT processing involves heating the oat milk to a very high temperature (usually around 280°F) for a short period, followed by rapid cooling. This process kills off any bacteria and mold, extending the shelf life of the oat milk. UHT-processed oat milk can be stored at room temperature for up to 6-12 months.
Aseptic Packaging
Aseptic packaging involves filling pre-sterilized containers with oat milk in a sterile environment. This prevents any contamination from occurring during the packaging process, reducing the risk of spoilage. Aseptically packaged oat milk can be stored at room temperature for up to 6-12 months.
Microfiltration and Ultrafiltration
Microfiltration and ultrafiltration are membrane filtration techniques that remove bacteria, mold, and other impurities from the oat milk. This extends the shelf life of the oat milk by reducing the risk of contamination.
Home-Made Oat Milk: Tips for Longer Shelf Life
If you’re making oat milk at home, there are a few things you can do to increase its shelf life.
Use Clean Equipment
Make sure to use clean equipment and sanitized utensils when making oat milk at home. This will reduce the risk of contamination and spoilage.
Store in Airtight Containers
Store your homemade oat milk in airtight containers, such as glass bottles with tight-fitting lids, to prevent contamination and spoilage.
Freeze It!
Freezing your homemade oat milk is a great way to extend its shelf life. Simply pour the oat milk into an airtight container or freezer bag and store it in the freezer.

What is oat milk and how is it made?
Oat milk is a plant-based milk alternative made by soaking oats in water and blending them with water. The mixture is then strained to remove the oats, and the remaining liquid is the oat milk. The process of making oat milk is relatively simple and can be done at home, but commercial producers often add additional steps such as fortification with vitamins and minerals, flavoring, and packaging.
Some commercial brands also use enzymes to break down the oats, making the process more efficient and resulting in a creamier texture. Additionally, some producers use a combination of oats and other ingredients, such as nuts or seeds, to create a blended milk alternative. Regardless of the method, oat milk is a popular choice for those looking for a dairy-free or vegan milk option.
Why does oat milk have a longer shelf life than other plant-based milks?
Oat milk has a longer shelf life than other plant-based milks due to its low acidity level and low water content. Oat milk has a pH level close to neutral, which makes it less hospitable to bacterial growth. This, combined with its low water content, makes it more difficult for bacteria and other microorganisms to grow and cause spoilage.
Additionally, oat milk contains a natural antimicrobial compound called avenanthramide, which helps to inhibit the growth of bacteria and mold. This, combined with proper packaging and storage, can extend the shelf life of oat milk up to 30-60 days when unopened, and up to 7-10 days when opened and refrigerated.
Is oat milk safe for people with gluten intolerance or celiac disease?
Oat milk is generally considered safe for people with gluten intolerance or celiac disease, as oats are naturally gluten-free.
