Does Maseca Expire?

If you have a box of Maseca that is a few months past its expiry, then you might want to read this guide before using it!

Does Maseca expire? Maseca can be used and stored in several different ways. If kept right, it can remain edible for up to a year or more under optimal storage conditions. However, if you have a pack of expired Maseca that you want to use then it would be best if you checked it for signs of spoilage first!

Read below to learn more about corn flour, what makes it last this long, and how to properly store it!

What Is Maseca?

Maseca is a brand that produces corn flour and tortillas. The company has been around for over 70 years and is at the forefront of corn flour production, as its parent company Gruma, is the largest corn flour and tortilla manufacturer in the world.

Maseca is finely powdered corn flour that resembles the consistency of all-purpose flour. Corn flour itself is an extremely common and widely used by-product of corn.

It is used all over the world for various purposes and has lots of culinary applications. For example, Maseca corn flour is used to make tortillas, tamales, tortilla chips, and tacos and can also be used as a thickener too.

Corn flour is made from ground kernels that are then refined and strained until the starch separates from the liquid (usually water) and gets deposited at the bottom.

The starch is then further processed and refined and then dried. The drying process leaves behind a cakey surface that is then broken down and ground a final time.

The resulting powder is referred to as corn flour and is sold under many brand names, including Maseca.

Since corn flour is made via the process of dehydration and only contains simple starches, this by-product of corn can have a long lifespan.

Can Maseca Go Bad?

Moisture is the enemy of food as it promotes the growth of bacteria and oxidizes food on the molecular level.

While properly stored Maseca can last up to 9 months to a year, if the corn flour is exposed to moisture through, let’s say, a wet spoon or a few drops of water, then that could lead to a cascading event that would compromise all of the corn flour.

See, when bacteria find favorable living conditions, they tend to increase in numbers. This increase is usually exponential with bacterial populations doubling every 20 minutes!

So, even if you bring a fresh batch of Maseca home, it has the potential to get spoiled with just a few wrong steps.

On the other hand, if Maseca is kept as indicated, it may be able to last longer, sometimes even past its expiry date.

But if dry Maseca is so resilient to spoilage, then why put an expiry date on the box at all?

The thing is, manufacturers are required by law to provide a best-before or expiry date for their products.

Furthermore, some products may not spoil after the expiry date but they may lessen in quality or flavor. This is especially true for cured meats and other opened canned or packaged goods too.

Does this mean that Maseca can become less effective past its expiry date? Not really.

Remember, corn flour is made up of simple starches and can also be considered to be the final by-product of corn.

You can also think of this ingredient in another way: since corn flour is made of a singular, powdered and dried ingredient, there is far less that can go wrong.

How Long Can Maseca Last?

No one can truly put an extended date on corn flour. Some people have used it after 1.5 years to success while others can use it for up to 11 months without worry.

The problem with using Maseca past its expiry date is that there is a lot that can go wrong in a year, in terms of storage.

For example, if you buy a fresh pack of Maseca during the start of the year and casually store it in a questionable cupboard and then not use it for at least 6 months, then there is no telling what would happen to the box.

The corn flour may become compromised via insects, or it may develop mold via excess moisture in the cupboard. So, if you come back after 7 months and decide to use the Maseca then you might just be better off buying a fresh pack instead.

On the other hand, if Maseca is stored properly in an airtight jar and kept away from sunlight and moisture then this ingredient may be safe to use in the long term.

What happens if you opt to use another brand instead? You can freely switch brands and even opt for the cheaper varieties in the supermarket.

However, most small-scale manufacturers that don’t produce in bulk may use stored or shelved corn instead of fresh produce.

This may affect the end product and you may end up with corn flour with a shorter expiry date than the competitors.

This is why we highly recommend sticking to the companies that have been doing this for several decades.

Sure, other brands may be excellent for short-term use, but if you want to take your time before using corn flour then it would be best if you opt for the premium variety.

How To Tell If Maseca Has Gone Bad

As mentioned, Maseca can be a highly resilient ingredient but it can also easily become compromised under certain circumstances.

Maseca corn flour can just as easily spoil if it is not stored in an airtight container and kept away from pests, moisture, and sunlight.

Furthermore, improper handling or bad cooking practices may also lead to rot. Here are some of the ways to detect spoilage in Maseca:

Foul Odor

Fresh or properly stored Maseca has a very neutral scent that smells like, well, nothing.

This is a good thing since it should make it easy for people to judge when it has gone bad. Maseca is free from moisture but as soon as you add even just a few drops into the pack, the corn flour may slowly start to rot.

This will result in a foul or rancid odor that will permeate the package. You can confirm your suspicions by scooping the powder from the bottom and then smelling it for signs of spoilage.

If you can pick up on a foul scent then it is best to just throw away the whole pack.

Also, another thing to consider here is that Maseca may take on stronger scents if it is kept near herbs or other strong-scented ingredients like garlic.

While this may not make the Maseca go bad, it will certainly make it difficult for you to judge based on its smell!

Molding

Mold is a very definitive sign of spoilage. Maseca can grow mold over time, especially if it is not kept the right way. Any type of mold or clumped-up pieces in the Maseca may indicate spoilage.

The mold may take on different colors but a general rule is to toss the entire pack if there is an inconsistent color in the powder.

Keep in mind that Maseca has a pure white color and mold is typically green, gray, or yellow, which would make it easy for you to detect spoilage.

Maseca is widely used around the world to make loads of delicious snacks and dishes and if kept right, it can easily be used over the long run without any issue!

Now that you know the dos and don’ts of using and storing Maseca, here are some related questions!

Can you use 2-year-old Maseca?

2-year-old Maseca may only be safe to use if it doesn’t show any signs of spoilage and if it has been stored properly throughout its storage duration.

Since it’s made of simple starch, corn flour may not lose its effectiveness over time but in some conditions, it may also become less effective.

Please keep in mind that even though Maseca is a low-risk and resilient ingredient, you should still always be careful of when and how you use it.

Can you freeze Maseca?

Yes, Maseca can be stored in the fridge or freezer to extend its shelf life. The trick to storing it in the freezer is to move the contents of the pack into an airtight and freezer-safe container.

Storing the Maseca in the box may lower its quality and may also compromise it when it is thawed.

How long will Maseca last in water?

Maseca is usually dissolved in water before it is added to soups, sauces, or gravies. This prevents the build-up of clumped-up corn flour blobs in food. When fully mixed in water, you may use the Maseca solution within the week.

You can also store the mixture in the freezer for up to 2-3 months. We recommend using the Maseca solution within 2-3 days for the best results, just make sure you mix well before use!
