Does Cornstarch Go Bad?
Indeed, cornstarch can go bad! This fine white powder is sourced from corn kernels' endosperm. Every food item has a shelf life, with some extending longer than others. While certain foods spoil independently, others may be affected by external factors like moisture. Though cornstarch has a lengthy shelf life, it becomes compromised when it comes into contact with moisture, which can stem from humidity or contact with liquids. Prolonged exposure to moisture can lead to mold, negatively impacting its viability.
It's essential to differentiate between cornstarch and corn flour as their storage rules differ. Corn flour comes from whole dried corn kernels and has a different texture and usage in cooking.
How Long Does Cornstarch Last?
Cornstarch remains stable until moisture exposure occurs. If kept dry, it has no designated expiration date.
Begin by checking the 'best by' date on your cornstarch packaging. If you see no signs of spoilage, it remains safe to use post the 'best by' date.
What contributes to cornstarch's longevity? Its lack of natural moisture is a pivotal factor. It is a dry powder, unlike other foods rich in moisture that spoil more quickly. When stored in a cool, dark environment, cornstarch can endure indefinitely.
How To Tell If Cornstarch Has Spoiled
Now that you know cornstarch can spoil, you may be curious about the signs indicating it's time for disposal. Look for the following signs:
It Appears Lumpy
Lumpy appearances do not definitively signify spoilage; however, if lumps form, it indicates moisture infiltration and impending spoilage.
You Notice A Bad Smell
A sour odor suggests spoilage. Fresh cornstarch should emit a pleasant corn-like aroma. If it smells off, it’s best to throw it away.
You See Mold
Any mold presence means you should dispose of the cornstarch immediately. Mold ingestion can lead to severe health issues such as food poisoning.
Bugs/Insects
If you discover tiny black or brown insects in your cornstarch, it indicates contamination. While pantry pests are not harmful, they can carry bacteria and compromise your health.
Sour Taste
If your cornstarch appears fine, but you want to ensure its freshness, taste a pinch. A sour flavor suggests it should be discarded to avoid ruining your dishes.
How to Store Safely
Knowing how to keep cornstarch fresh is vital for longevity. Implement the following strategies:
Use Airtight Containers: Upon purchase, transfer cornstarch from its original container into an airtight one. Label it for identification, ensuring it doesn’t get confused with other similar items.
Store in a Cool Dark Place: Place cornstarch in a pantry away from light and moisture. Direct sunlight should be avoided for prolonged freshness.
Avoid Moisture: Keep cornstarch away from liquids. Accidental spills may lead to spoilage.
What Is Cornstarch Used For?
Thickening Agent: Cornstarch is commonly used to thicken sauces, soups, and gravies.
Creates a Crispy Crust: Adding cornstarch to waffles or pizza dough can achieve a crispy texture.

What Happens If You Eat Bad Cornstarch?
Fortunately, there aren’t well-documented cases of severe illness caused by spoiled cornstarch. While digesting spoiled food can lead to discomfort, it’s prudent to dispose of any cornstarch that you suspect might be bad.
Does Cornstarch Lose its Thickening Ability Over Time?
Though it's a prevalent thickening agent in the culinary world, you might wonder if it loses its potency. Fortunately, cornstarch maintains its thickening properties over time, making it a reliable ingredient.
