Yes, cornstarch can go bad if not stored properly. Under ideal conditions, its storage life can extend to many years. Cornstarch that has been exposed to warm water has lost its life span. Cornstarch is a product that few people use regularly. The expiration date on the package will eventually make you worry if the product is still good to use or not.
Many individuals have concerns about corn flour, even though it’s nothing more than a powder refined from the starch in corn kernels. The main problem is whether or not it would lose its thickening power after being used for a while.
Corn flour should be stored in the same manner as wheat flour. For this reason, it requires a cool, dry, and somewhat constant temperature environment. However, if you don’t have access to a pantry, any kitchen cabinet will do. Cornstarch isn’t improved by being refrigerated, so don’t do it.
There are several reasons why cornflour packaging needs to be secure. Primarily, it prevents the powder from being exposed to harmful environmental factors, including dampness and odours. A second benefit of storing cornflour in an airtight container is that it deters insects and other pests that might otherwise be attracted to the flour.
5 Warning Signs That Your Cornstarch Gone Bad
1) When Bugs Showed Up
There are bugs in your cornflour, and that’s the first red flag that something is wrong. These organisms are usually very little and dark in colour i.e. black or dark brown, but they can be any size. You should be able to spot them easily in your bag of cornflour.
If you look at these bugs and assume they’re harmless, you could decide against throwing out your cornflour. We can safely ignore these insects. It’s important to remember that some of these insects may carry harmful bacteria or parasites. Despite your best efforts, insect larvae or eggs may still be in the cornflour.
2) The Existence Of Mold
All of the moldy food at your residence must be thrown away immediately. Numerous studies have shown that mold contributes to many health issues, including weakened immune systems, respiratory infections, and even mortality.
The bags of cornflour should be thrown away if further inspection reveals the presence of grey mold. If you suffer from mold allergies, this is crucial.
3) Your Corn Starch Smells Bad.
Another indicator that your cornflour has gone bad is its odour. Corn flour stored for a long period should be smelled before being used. Cornflour typically has a very distinct maize aroma. Occasionally, I think of the corn harvest back in my hometown when I was a kid.
If you have a strong preference for products that contain corn flour, you will undoubtedly notice the difference. Cornflour with a sour aroma has likely gone rotten. Bad corn flour has the same powerful, unpleasant odour.
4) The Sour Taste Is A Sign.
My cornflour is free of any insects, mould, or off flavours. Is it edible? Yes. However, there is something else you should double-check. It would help if you tried cornflour before using it in a recipe. A gradual approach is required to establish this routine.
Before adding cornflour to your soup or sauce, take a quarter of a teaspoon and try it. You will no longer be able to utilize your cornflour for making soups if the sourness has completely overpowered the flavour. Please get rid of it and replace it with something new.
5) When The Cornflour Is Lumpy
Cornflour that has become lumpy should not be thrown away. However, clumsiness indicates that water has gotten into your cornmeal. The water has contaminated the cornflour.That bag of cornflour will quickly get infested with mould if it gets damp. Cornflour can be cooked if you insist on not discarding it. Not until you give it a good whiff and a taste, though.
Tips To Store Cornstarch
1) Keep Your Cornstarch In a cool, Dark place.
Keep your corn flour jars or bags out of direct sunlight in the dark. Because of the high heat it emits, sunlight, like many other flours, will destroy your cornflour.
2) Avoid Exposing Your Cornstarch To High Temperatures.
Hot temperatures can shorten the shelf life of corn flour because they cause it to spoil more easily.
3) Keep Moisture Out Of Your Cornstarch
Store cornflour carefully and avoid exposing it to air at room temperature for too long. There is no remedy for damp cornflour other than tossing it away or using it immediately.
4) Never put it in the fridge.
The only moisture in corn flour is in the form of dust from flour. Since this is the case, starch may be stored for a long time. If you store the powder in the fridge without a suitable seal, it will absorb the moisture and become lumpy.
What happens If You Use Expired Cornstarch?
1) Your blood sugar level will go up
As cornflour is deficient in fibre, a key vitamin that delays the absorption of sugar into the bloodstream, your blood sugar level will rise. This can produce a dramatic increase in blood sugar levels.
2) It’s hazardous for your cardiovascular system
Cornstarch belongs to the class of carbohydrates known as simple sugars. Consuming excessive refined carbohydrates has been linked to an increased risk of developing coronary heart disease.
