How Long Does Rice Flour Last
Rice flour may last for several hours if it is not stored properly at room temperature. You may store it in the fridge to preserve it for a longer period of time. You may increase the shelf life of the rice flour by freezing it. Make sure that you should pack it in an airtight container.
In general, white rice flour will last at least 1 year in your pantry, and brown rice flour up to 6 months. Homemade rice flour, stored properly in an airtight sealed container in a cool, dry area, will last for 3 months. Rice flour will last indefinitely if stored in a sealed container, can, or plastic ziploc bag in a cool, dry, and dark place, away from direct sunlight and heat.

Since rice flour is a shelf-stable food, so you can store it in an air-tight container, or plastic zipper bag, in a cool, dry, dark corner of your pantry or kitchen cupboard. You can also wrap a plastic wrap or foil around an air-tight container that contains rice flour to provide additional protection. Using an air-tight container or a plastic zip-lock bag also will make sure the rice flour does not absorb smells and flavors from different foods present in your refrigerator.
If the airtight containers get damaged or leak, it may let in harmful bacteria into the flour. Flour is typically stored in airtight containers to prevent loss of moisture and spoilage. Most flours may last for long periods, but when stored improperly, can become rancid, smelling bad with funny tastes. Contains means whole-grain flours are more prone to oxidization — a process that causes them to turn off — and will not last as long.
This makes them prone to oxidation, and may not last as long as the others. This is particularly true for these lower-fat flour types, but whole-grain flours also may last as long as they are stored in a dry, cool, dark corner of your pantry. The most common flour type–general, all-purpose white flour–can last for about one year in a pantry when stored properly, and infinitely longer if stored in a refrigerator or freezer. As mentioned earlier in our guide on shelf-life for flour, all types of flour last much longer if stored properly in a freezer.
Below are the general guidelines for how long you can expect various types of flour to last if stored properly. While we gave you these general guidelines, you should know that how long a flour will live beyond its best-by date depends on a number of different factors, like how it is stored properly and how it is manufactured.
Like many other foods, flour will stay good well past the date best before or best before used which you can find on the original container. If the flour smells moldy or sour, the flour is likely expired and long past its best by date. If you stored your flour correctly, then you can rest assured that you can use it. If flour is stored correctly, it may last for two years, and you may be able to use it in several recipes.
With the exception of white flour, which will dry out instantly as soon as it hits the expiration date, all other types of flour may still be used unless it is already spoilt. All-purpose flour, for instance, has a shelf-life of 6-8 months, though it can last for up to 1 year if kept refrigerated, and up to 2 years when frozen (7). Once opened, keeping your flour refrigerated may increase its shelf life up to eight months. While you can prolong flours shelf life in your freezer, your pantry is also a good place as long as it is sealed in the container.
| Storage Places | Shelf Life |
| Freezer | 6 Months |
| Fridge | 3 months |
| Pantry | 2 years |
| Room Temperature | Few hours |
To prevent mould growth, keep flour out of humidity and water when you are storing it in your fridge or freezer. Colder temperatures may help slow down oil degradation, which is why storing your whole-grain flour in a freeze-safe container is particularly useful. Brown rice flour, on the other hand, spoils far more quickly, and you will want to store it in the freezer to prolong its shelf life, which is from around three months to closer to one year.
Overall, dried white rice can last for up to 2 years at room temperature, whereas brown rice will last for only around 6 months when kept cooler. The refrigerator extends the time by up to three months, and it is best for a year if you store both the white flour and brown rice in a freezer. So, you can expect whole-wheat flour to last three to six months after you get it home from the store, or six to eight months in the freezer. Regular flour typically lasts 6-7 months after the print date, whereas whole wheat is generally good for just another 4-6 months.
Because whole wheat flour is made using the whole wheat, it keeps a few essential oils in the grains, and those will break down and give off a rancid flavor as time goes on. It is always best to toss your flour out if it smells bad or shows signs of mold. It is much more likely your flour is going to get weevils or flour beetles in it well before it goes rancid.
The presence of flour beetles does not mean that your flour has gone bad–you can either sieve it and its eggs out, or put the flour in the freezer for several days to kill it. Make a habit of sniffing each bag of freshly opened flour, even if you are new to those flours and you are unsure what they are supposed to smell like. I sniff containers whenever I use my flour, both for the satisfaction of smelling grains, but also for monitoring freshness.
If you are ever unsure, just smell it, and make up your mind whether or not flour is safe to use past its expiration date. Your flour might still be safe to use, even past its best-by date. White flour typically keeps for about one year in your pantry, unopened. All-purpose flour may last between six and 12 months from purchase if stored unopened in the pantry.

Oatmeal, Coconut Flour, Gluten-free Flour: If you keep oat flour in your pantry, it will probably last for a maximum of three months. If you follow the instructions that we outline here, and you ensure that the flour is kept under the perfect conditions, then you can be assured that your flours will last for an extended period of time. Yes, you can store rice flour in your fridge, but care must be taken because moisture levels are pretty high in a fridge, and this may negatively affect the flours quality and may lead to lumps.
Can you use flour 2 years out of date?
To indicate how long they will remain fresh, most packaged flours have expiration dates (also known as best-by dates) written on the bag. These markings, however, do not indicate safety and are not required. As a result, even after the best-by date, your flour can still be safe to consume.
Is it safe to eat expired flour?
Short answer: Yes. If your flour is actually over its expiration date, the powder’s molecular structure will alter and might possibly release toxic substances. The “best by” or “better if used by” date that may be found on the original container, however, will not be reached for flour like it is for many other goods.
How do you store rice flour for a year?
Although rice should be kept at a constant 70° F with oxygen absorbers to prolong shelf life, grains, including rice, should be stored at a temperature of 40°F or below. Rice flour may be kept for up to 30 years in colder storage facilities if it is enclosed in containers that are oxygen-free.
