What is the Shelf-Life of Coconut Milk?

What is the Shelf-Life of Coconut Milk

Whether it is bottled or canned Coconut Milk, the shelf-life of Coconut Milk is relatively shorter. It only lasts for a year. But there is no harm in consuming it a couple of months more past its use-by date, provided that it is not spoiled and stored properly.

After opening the bottle or carton of Coconut Milk, you must refrigerate it and consume it within a week. It is important because the shelf-life of the opened Coconut Milk is only five to ten days.

Coconut Milk keeps its quality and taste for a couple of weeks more after its use-by date. However, you can’t expect the Coconut Milk to last for more than a week after the best-by date.

After opening, it has a shelf-life of ten days, depending upon manufacturers’ recommendations.

Items Pantry Fridge
Unopened and Unrefrigerated Coconut Milk Use-By Date Plus Three to Six Months
Unrefrigerated Opened Coconut Milk Five to Ten Days
Refrigerated Unopened Coconut Milk Best-By Date Plus Three to Seven Days
Refrigerated Opened Coconut Milk Five to Ten Days
Canned Unopened Use-By Date Plus Six to Twelve Months
Opened Coconut Milk Five to Ten Days
Homemade Coconut Milk Three to Four Days

These are the estimated period to tell how long it can keep its quality and not the expiry date. You can use the Coconut Milk even after the printed use-by date, provided that it has no spoilage signs.


What are the Spoilage Signs of Bad Coconut Milk?

What are the Spoilage Signs of Bad Coconut Milk

There are a couple of spoilage signs to look for to know if your Coconut Milk is still edible or if it has gone rancid. If you see any of these spoilage signs after opening the carton or bottle of Coconut Milk, don’t use it. There is a high chance of getting food poisoning with severe diarrhea and nausea after drinking spoiled Coconut Milk.

Mold Formation

Since Coconut Milk has high fat and small sugar content, it tends to develop mold faster. The mold formation on the surface may look like black or green circles floating on the surface of the Coconut Milk.

If it is continuously refrigerated after opening, you may also see small chunks of mold growth at the bottom of the Coconut Milk jar. If you see mold growth on the surface, discard the Coconut Milk immediately.


As your Coconut Milk starts to rot or turn rancid, it gradually forms small chunky white pieces and thickens after that.

The chunkiness of the Coconut Milk after rotting will be different from the solidified Coconut Milk, which you usually see in the bottle.

Taste and Smell Change

If there is no mold growth in the Coconut Milk and you have not noticed any abnormal coagulation occurring, you must conduct a taste and smell test.

Fresh Coconut Milk smells like real coconut, and when it rots, the smell changes. Coconut Milk won’t have a strong smell like vinegar or a bite. So, if you notice any unpleasant or strange smell in your Coconut Milk, it indicates that the milk has gone bad, and you must discard it.

Apart from these spoilage signs, if you notice any signs that are iffy or off, discard the Coconut Milk to be on the safer side.


What Happens If You Drink Coconut Milk After Expiry?

There is no harm in drinking Coconut Milk past its use-by date, provided that it is properly stored as recommended and no spoilage sign is noticed. Drinking old Coconut Milk after its use-by date won’t make you sick. But once it develops spoilage signs, the Coconut Milk becomes inedible, and drinking such milk can make you severely ill, including food poisoning.

Drinking spoiled Coconut Milk can develop food poisoning and other symptoms like upset stomach, painful cramping, vomiting, fatigue, fever, and diarrhea.

You don’t have to worry if you ingest a small portion of spoiled Coconut Milk. But things won’t be the same if you drink it in large amounts or even in a moderate amount of spoiled Coconut Milk.

After opening the canned Coconut Milk, you must refrigerate it continuously in a sealed or airtight container to keep it fresh and edible for up to ten days.



According to the official recommendation of the USDA, opened perishable items like Coconut Milk must be discarded if it sits outside the refrigerator for more than two hours.

It is a strict rule, and you must follow it for all half-open perishable foods, including Coconut Milk. But the rule is only for the opened can of Coconut Milk and not for the sealed and unopened pack of Coconut Milk.
