In this article, we’ll explore the reasons why almond milk can turn blue and what you can do to prevent it from happening.
From proper storage techniques to understanding the chemical reactions at play, we’ll give you all the information you need to keep your almond milk fresh and delicious.
So, let’s dive in and uncover the mystery of blue almond milk!
Why Did My Almond Milk Turn Blue?
The blue hue in almond milk is caused by a reaction between the almond proteins and the acidity of the milk. This reaction can also be caused by bacterial contamination, as well as poorly stored almond milk.
When shopping for almond milk, it’s important to look for ones that display expiration dates and a list of ingredients. This will help you determine the quality of the milk before you buy it. Once you’ve purchased your almond milk, it’s crucial to store it properly.
Be sure to store your almond milk in a cool and dry place, and consume it before the expiration date. It’s also recommended to shake the milk before consuming to make sure the proteins haven’t broken down and caused the almond milk to change color.
In addition to these steps, make sure to check the milk regularly. If you see it’s turning blue, discard it right away and buy a new carton. If you take the necessary precautions, you can enjoy almond milk without any worries of it turning blue.
What Causes Almond Milk To Turn Blue?
As previously mentioned, the blue hue in almond milk is caused by a reaction between the almond proteins and the acidity of the milk. This reaction can also be caused by bacterial contamination, which is why it’s important to buy high-quality almond milk and store it properly.
When the almond proteins react with the acidity of the milk, it causes a chemical change that results in a blue color. This reaction can also occur when the almond milk is exposed to air or light for too long, or if it’s not stored at the right temperature.
Bacterial contamination can also cause almond milk to turn blue. If the milk is not properly pasteurized or if it’s stored in unsanitary conditions, it can become contaminated with bacteria that can cause the blue coloration.
To prevent your almond milk from turning blue, make sure to buy high-quality almond milk that displays expiration dates and a list of ingredients. Store your almond milk in a cool and dry place, and consume it before the expiration date. Shake the milk before consuming to ensure that the proteins haven’t broken down and caused the color change. And always check your almond milk regularly for any signs of discoloration or bacterial growth, discarding any contaminated or expired milk immediately.
The Science Behind Blue Almond Milk
The blue color in almond milk is caused by a chemical reaction between the almond proteins and the acidity of the milk. This reaction creates a blue pigment that can alter the color of the milk.
The blue hue in almond milk can also be caused by bacterial contamination, which can occur during the manufacturing process or due to improper storage. Bacteria can produce pigments that can alter the color of the milk, including blue.
To prevent blue almond milk, it’s important to store it properly and purchase high-quality almond milk. Proper storage includes keeping the milk away from direct sunlight and storing it in an area with a consistent temperature. Selecting almond milk made with natural ingredients can also help ensure its quality.

Proper Storage Techniques For Almond Milk
Proper storage techniques are vital for maintaining the quality of your almond milk and preventing it from turning blue. The shelf life of almond milk depends on the type of almond milk and how well it is stored.
Homemade almond milk has a shorter shelf-life than store-bought varieties, usually lasting only 3 to 7 days even if properly stored in the refrigerator. Store-bought refrigerated almond milk tends to be ultra-pasteurized, which is a heating and cooling process that kills bacteria and extends shelf life. Once opened, it should last up to 7 days when properly stored in the refrigerator.
Shelf-stable almond milk has the longest shelf life. If properly stored, it will typically last one to two months unopened and up to 10 days once it’s opened and refrigerated. This type of almond milk can be stored long-term in the pantry when unopened, and it comes in a Tetra Pak or similar type of aseptic packaging that prevents light, oxygen, and bacteria from contaminating the milk on the inside.
To properly store your almond milk, keep it in a cool and dry place away from direct sunlight, heat, or moisture. Make sure to check the use-by date printed on the carton and consume the product within a couple of weeks of that date for the freshest tasting almond milk. Once opened, store it in the refrigerator and make sure to use it within the recommended time frame for that type of almond milk.
It’s also important to shake the almond milk before consuming it to make sure the proteins haven’t broken down and caused the almond milk to change color. If you notice any signs of spoilage such as a sour taste or smell, thicker texture or clumps, discard it immediately and buy a new carton.
By following these proper storage techniques, you can enjoy fresh and delicious almond milk without worrying about it turning blue or spoiling prematurely.
The Effect Of Temperature On Almond Milk
Temperature plays a crucial role in the shelf life of almond milk. Properly storing almond milk at the right temperature can help to prevent it from turning blue or going bad too quickly.
Almond milk that is stored at room temperature can spoil faster than milk that is stored in the refrigerator. For example, shelf-stable almond milk that is unopened can last for up to two months at room temperature. However, once it’s opened, it should be consumed within 10 days if stored in the refrigerator.
Refrigerated almond milk, on the other hand, has a shorter shelf life once it’s opened. It should be consumed within seven days of opening to prevent it from going bad. It’s also important to store refrigerated almond milk properly by keeping it in the coldest part of the refrigerator and away from direct sunlight.
How To Tell If Your Almond Milk Is Spoiled
Almond milk can go bad and it’s important to know how to tell if your almond milk is spoiled. One of the most telltale signs of almond milk going bad is the smell. Once the drink is spoiled, it will lose its nutty and fresh smell. Take a good sniff at your milk; does it smell sour? Does it smell pungent? Does it smell any different from how almond milk should smell? If the answer is yes, it’s time to throw it away.
Another way to check if your almond milk is spoiled is by examining the carton. If the carton is bloated, puffed-up, or leaky, throw out the milk. The dairy-free milk isn’t necessarily spoiled, but there’s something seriously wrong here. Better safe than sorry.
When examining almond milk, pour it into a glass and look for color and smell changes first. Visual and texture changes should be easy to spot; same thing for an altered odor. If the drink smells similar to sour milk, it’s bad already and you should discard it. Then make sure to check the consistency of the liquid. If it has any thick parts or is curdled, throw it away. The last thing is the flavor – if your almond milk doesn’t taste right, it’s probably not safe to consume.
It’s also important to ensure the drink isn’t opened for more than 7 to 10 days, and that it’s not expired for longer than a week if it’s the refrigerated variety. Going through the process outlined above makes sense only if the date is within a reasonable period. If the almond milk is already opened for two weeks, just toss it out. Same thing if it’s the refrigerated variety and it’s more than two weeks past its date.
