How Can You Tell If Powdered Sugar Has Gone Bad?

If you do not bake that often, you may have some stored powdered sugar in your pantry. If you’re unsure if your leftover powdered sugar is still of good use, here are some tips from us to tell if your powdered sugar has gone bad.

1. It has clumps.

An old bag of powdered sugar may develop clumps over time. However, you don’t have to feel upset about these little chunks. They have don’t necessarily ruin the quality of the powdered sugar.

A quick fix to a clumped powdered sugar is to use your hands to break the solidified sugar or sift it thoroughly back to its powder form.

Small clumps will form if your powdered sugar is exposed to damp air. If the clumps are little, you can remove them. But if they are large and hard to break, you must throw them away. The hard lumps indicate that the sugar has gone bad. (*)

2. It smells odorous.

It is easy to identify the potent smell of a good pack of powdered sugar. Note that fresh powdered sugar has a sweet vanilla-like scent. If you notice that your powdered sugar smells funny, blame the oxidized cornstarch in it.

Notably, it may give off moldy, fermented starch or strong odors. Thus, this means that your powdered sugar is no longer suitable for use.

Furthermore, your powdered sugar will go bad if exposed to strong smells in the environment or storage. For instance, if you store an opened pack of powdered sugar near your laundry soap for an extended period, it will eventually smell like laundry soap!

3. Change in color.

The color of powdered sugar is pretty white. If you observe discoloration in your sugar, we advise you not to use it anymore.

4. Presence of molds.

Moisture is one factor that encourages mold growth on your powdered sugar. If you notice these molds on the surface of your sugar, discard them immediately.

How to Store Powdered Sugar Properly?

Storing your powdered sugar in the proper condition can significantly extend its shelf life by multiple folds. Make sure to keep it in a cool and dry place like your pantry. (*)

Always keep the powdered sugar package in an airtight container and make sure to have it sealed tightly to prevent moisture and pantry pest infestation. You may use a freezer bag to store powdered sugar. Make sure to squeeze out all the air from the bag before sealing.

To keep it safe for a longer time, make sure to store it away from direct sunlight as it can also reduce the shelf life.
