Does coconut flour go bad?

In this brief article, we will answer the question “Does coconut flour go bad?” we will also discuss the shelf life and storage methods of coconut flour.

Does coconut flour go bad?

Yes, coconut flour does go bad. It does not last nearly as long as all-purpose flour and degrades in quality much more quickly.

The main reason that makes coconut flour last less is its relatively high-fat content compared with staple flour, for instance, white wheat flour (no whole).

Makinde and Eyitayo [1] reported the content of coconut flour as being 5.43 g in 100 g of flour, approximately twice the fat content of white wheat flour (2.9).

A search for the fat content of commercially available coconut flour reveals that this value can be as high as 13 g of fat in 100 g of flour. 

Coconut fat deteriorates over time, as demonstrated by Chandram and others [2], giving rise to off-flavors and off-odors that may result in rejection of the product. 

In another study, Arumugam and colleagues [3] observed that fat oxidation of coconut flour increased significantly over 10 months of storage at room temperature.   

This effect can be boosted if the coconut flour is improperly stored. For instance, Chandram and others [2] found that markers of fat deterioration increased significantly  over 2 months of storage at 60°C. 

Besides chemical alterations, coconut flour can be lumpy, notably if stored under high-humidity environments. Moisture pickup may sequentially favor the development of fungi.

What is the shelf life of coconut flour?

If correctly stored and handled, the shelf life of coconut flour is 1 year unopened, and 30 days after opening. 

This relatively short shelf life, notably compared with white wheat flour for instance (which last indefinitely), can be attributed to the chemical composition of coconut flour with respect to fat.

How to tell if your coconut flour is not fresh?

Good quality coconut flour has a light cream color and a sweet and nutty aroma. The following are signs of spoilage:

  • Flour that is very clumpy: may indicate that the flour has picked up moisture from the surroundings. Be careful because this may have favored the growth of molds.
  • Strange odor: coconut fat may become rancidity due to fat deterioration.
  • Aside from that, insects may find your coconut flour to be an easy target. If you discover them in your flour, toss the flour out.

How to store coconut flour?

To keep coconut flour fresh, store it in a cool, dry spot and away from light. After opening, store it also in a cool place and make sure to keep the bag tightly sealed to avoid contact with air.

You can choose different storage options, including:

Room temperature (in the pantry):

Make sure the pantry is clean, away from heat and moisture. 

Chandram and others [2] found that markers of coconut fat deterioration increased significantly over 2 months of storage at 60°C. Thus, storing your flour in hot places will contribute to reducing its quality and shelf life. 


Storing coconut flour in the refrigerator,  unopened or after opening, helps prolong its shelf life and better preserve its freshness because chilling temperatures reduce the velocity of degradation reactions [4], for instance, fat deterioration.

Remember to always keep the flour tightly sealed to reduce contact with air and absorption of smells of other ingredients. 


Freezing reduces drastically chemical reactions and microbial growth [4], thus, it keeps coconut flour quality even longer than in the refrigerator, always in tightly sealed bags or containers.

Frozen, coconut flour may last three to four months [4].

Is it possible to use coconut flour that has passed its expiration date?

Coconut flour prints a “best-before” date, not an expiration date. This means that if your flour does not show any signs of deterioration, it is safe to use, although it is not at its finest quality.

If the product appears in good condition but was stored in unfavorable conditions, simply discard it. Improper storing conditions could, for example, favor the development of molds, which could produce toxic compounds.
