How Long Does Powdered Sugar Last? Does Powdered Sugar Go Bad?

The shelf life of this depends on a lot of factors like storage, variety, and others.

These are of two types one is commercial, and the other is homemade.

Some people prefer buying table sugar and grinding it at home, so both these have a different shelf life.

That is because commercial powdered sugar contains preservatives that prevent mold.

Therefore, one can use this even beyond its best-by date, about 1 to 2 years.

If you offer appropriate storage, you can expect it to last longer for up to 4 years after the best-by date.

However, ensure you do not consume it right away, as it might contain bacteria.

Using old and contaminated powdered sugar will cross-contaminate your entire recipe; therefore, it would be better to check for bad sugar before adding it to your recipe.

How to Tell if Powdered Sugar Has Gone Bad?

  • Formation of Lumps

When you are looking for signs to identify bad sugar, you can see its texture.

That is because as you increase its storage period and it gets exposed to moisture, then it will become lumpy.

Homemade powdered sugar gets affected by humidity in no time, but commercially produced sugar contains added preservatives that restrict moisture.

  • Off or Unpleasant Odor

When you buy this, then it has the pleasant and strong essence of vanilla.

However, as you begin to store it and increase its storage period, then this sweet aroma fades after some time.

After prolonged unfavorable storage, this aroma turns into a foul odor.

So try to sniff the sugar; if this gives an unpleasant odor, you should do it immediately.

  • Mold Growth

You can closely examine the content and see if there are molds present.

The white-colored particles get some spots of grey or any other color if they have gone bad.

Mold formation happens when the sugar is kept close to moisture for an extended period.

So if there is mold growth, then you need to throw all the content out, as even though spots are on a specific area, the whole content will get affected by bacteria.

How to Store Powdered Sugar?

  • Store Away From the Strong Odor

You might have noticed that you have stored the sugar recently, but still, it’s offering a foul odor.

This is a common problem because people ignore the food item around which they are storing it.

If you keep sugar around food items that have a strong smell, then they develop a foul odor in no time.

Thus one needs to store powdered sugar away from strong smells for quality storage.

  • Seal the Jar Tightly

As explained earlier, moisture is your biggest enemy, as once the content is affected, it will go bad no matter how you store it.

Therefore, keep that in a sealed jar to avoid moisture.

You can use an airtight container or glass jars as they also restrict heat.

  • Pest Free Storage

This does not need refrigeration or freezing and can retain its quality easily if stored at room temperature.

So people choose kitchen cabinets and pantries for storage, but these are infested with pests, making this go bad.

Thus it would be best if you made sure that our cabinets are free from pests and bugs.
