Does Flour Expire, and What Happens if I Use it After it Does?
Flour is one of the most important ingredients in baking. The quality of baked goods depends on the freshness of the flour. Its freshness is also dependent on its shelf life and the manner in which it gets stored. It is for this reason that people ask how long does flour last.
Shelf Life of Flour
All ingredients have a definite shelf life. This is the period of time wherein one can ascertain the best possible quality or freshness of the food product. Different food items have their own shelf life. Some last longer than others.
Does flour expire? Yes, it does. The shelf life of flour can range from as short as 4 months to as long as 2 years from their best-by dates. There are also factors that can affect the overall quality of these ingredients. Exposing them to moisture can shorten the shelf life. This makes them expire a lot faster.
The type of flour can also be a major factor as to the duration of its peak freshness. All-purpose, rice, and potato variants can last between 6 and 8 months from their best-by dates. Corn flour can last anywhere between 9 and 12 months. Self-rising and whole wheat varieties can last from 4 to 6 months. Flour made of cornmeal can last up to 2 years.
The place of storage can also be a major factor. Storing them in the refrigerator can almost double the ingredient’s shelf life. For example, white flour can last about 1 year beyond its best-by date when placed in the pantry. If you put this in the refrigerator, you can extend its usability up to 2 years.
So, when does flour expire? If you have to be strict about it, a food product’s best-by date determines its expiry. You should be able to ensure the highest possible quality of the ingredient if you can use it within the printed date. It is still possible to use it beyond the best-by date. However, do not expect that its quality or freshness will be the same.
Determining the Freshness of Flour
There are instances when you do not have a best-by date. This can happen in repacked items. It is important to learn how to tell if flour is bad or is still good for consumption.
One way you can determine the freshness of this baking ingredient is by smelling it. Fresh ingredients will not have a very strong smell. You will notice a faint scent that is similar to clean, fresh grain. If you smell a musty or an off odor, it is often a sign that you have an old flour.
A rancid smell is often a good indicator of the foul state of the food. This is always the case in whole wheat varieties. Manufacturers use the whole grain. It can retain some of the grain’s essential oils. Such oils can degrade over time, contributing to the rancid smell.
Sometimes, weevils can inhabit the food and lay their eggs. These bugs can secrete different liquids into the flour and adversely affect its characteristics. This can happen if one did not store the ingredient in the correct manner. So, can flour go bad? Yes, it can. Poor storage practices can allow the entry of insects into the ingredient. This can turn it bad, even though the food item is still within its shelf life.
Moisture can also have an impact on the freshness of dry ingredients. You may notice clumps in the powder. These are an obvious sign of moisture ingress. Organic growth on the powder’s surface can also signify the interaction of moisture and the powder. It would be best to discard the food altogether.

Using Flour Beyond its Expiry
Can you use expired flour? You can use this ingredient within its best-by date for the best possible results in your baking. As already mentioned, it is still possible to use the ingredient beyond its expiration date. However, one has to know the recommended period of time for each type of powder. One also has to take into consideration the smell and appearance of the food item.
If the smell is not very offensive, then you can still use it. This depends on your personal preferences. There are some people who do not like to use ingredients that have even the slightest of an unusual smell. Others are okay with it.
You can taste a small amount of flour. If you like its taste, then there should be no problem including it in your dish. However, if you find the taste repulsive, then it would be better to discard the food item. Replace it with a new one or a suitable alternative.
Keeping Your Flour Fresh
The correct storage of baking ingredients is critical to ensuring their freshness. One should store an unopened package in a dry and cool area of your house. If it is too hot, there is a chance of increasing the moisture level in the room. This can permeate into the package and affect the quality of the ingredient.
The pantry offers the best place for storing dry ingredients. A kitchen cabinet can be a good alternative if you do not have a pantry. Make sure that the cabinet is far from potential splashes of water.

Opened ingredients require a very different storage solution. There are two ways you can do this. One is to pour the contents of the opened package into a storage container that has an airtight lid. This is crucial in order to prevent the entry of moisture, insects, and other potential contaminants. The second method is to retain the ingredient in its original packaging. You can then put the package into a large airtight container.

It is also possible to store your flour in either the refrigerator or the freezer. Storing whole-grain varieties in the refrigerator can extend its usability by another 6 months from its best-by date. If you store it in the freezer, you get to extend it for about a year.
All food items have an expiration, including dry baking ingredients. Knowing how to store them the correct way can help you prolong the usability of these ingredients.
