Some Insightful Background About Frozen Pizza

As you might know, pizza is a traditional dish of Italy and has been loved since its birth. The market for pizzas was huge, so food manufacturers couldn’t overlook that opportunity. Frozen pizzas are a convenient invention that works the same way as instant noodles.
While enjoying frozen pizzas, you may wonder why that seemingly unpalatable pizza product could have stood so unwaveringly to the test of time. The two adjectives to explain this are “convenient” and “tasty”.
What Is A Frozen Pizza?
People who are unfamiliar with this fast food may assume it’s just pizza put in the freezer for storage. It’s got more of a story than you might think.
Frozen pizzas are also uncooked premade pizzas that have been flash-frozen and sold in that state so that buyers will bake them in their own oven.
Following the invention of the quick freeze method in 1924 (1), frozen pizzas were later produced en masse in industrial machines with the production capability of thousands of pizzas in just seconds.
Pizzas had been a staple in the US for a very long time, but it was not until the 1950s that frozen pizza became a popular product in the supermarket. The trend of “read-to-cook pizzas” started in Boston and gradually spread to other parts of the US.
Initially, frozen pizzas consisted of a very simple and easy-to-find set of ingredients, such as flour, yeast, water, spices, mozzarella cheese, vegetables, and toppings of various kinds. The ratio of ingredients varies differently between manufacturers.
Similar to other frozen products, industrial additives and preservatives are necessary to keep the product lasting longer.
Most frozen pizzas have a crispy and crunchy crust as a result of baking. Different sizes of crust serve as a base to hold tomato sauce, blends of cheese, and toppings like pepperoni, bacon, sausage, ground beef, or vegan ingredients.

Types Of Frozen Pizza
Many types of frozen pizzas have been inspired by traditional baked pizza, and the simplicity of frozen pizza hasn’t changed much. They all boil down to two major categories: thin-crust and thick-crust frozen pizza.
Thin-crust frozen pizza closely resembles traditional pizza. Some of the most famous thin-crust pizzas are New York pizza, St. Louis pizza, and New Haven pizza.
On the other hand, thick-crust frozen pizzas come with thick bases to be able to hold multiple layers of toppings. Remarkable thick-crust pizzas are Chicago deep-dish pizza, Sicilian pizza, and Detroit pizza.

This staple contains a lot of nutritional content that is enough to supply you with energy to function in half of the day. Most pizzas are rich in energy fat, proteins, and carbs. Their content of sugar and sodium is also significant (2).
Generally, carbs and calories are the most prominent components of a frozen pizza. Different pizzas come with different toppings and vegetables, so the nutritional contents vary greatly between them.
Processed foods like frozen pizzas are high in unhealthy components. They contain preservatives and unhealthy fats. People who have obesity, blood pressure, and heart problems should think twice before munching on this kind of pizza.
Can Frozen Pizza Go Bad?
Most people think frozen pizza can’t go bad, but that’s not the case. Frozen pizzas can outlast many foods in your freezer, but they are not a kind of magical food that can withstand time. At some points, you should consider throwing them away.
Your frozen pizza contains a lot of ingredients, such as dough, cheese, tomato sauce, and many other toppings like ham, pepperoni, mushroom, sausage, etc. Each ingredient comes with a different shelf life.
However, thanks to preservatives and cold storage conditions, frozen foods like frozen pizza or vegetables can still be consumable after the expiration date.
Anyway, when an ingredient goes bad, it can lead to the spoilage of the whole pizza in a short time. Eating spoiled pizza can lead to food poisoning or food-borne illness. Some symptoms are stomach ache, diarrhea, and vomiting.
Various factors can make your frozen pizzas become heaven for bacteria and the like. Here are some of them:
Long Exposure To The Air
If you unpackage your frozen pizza and forget it outside for some days, your pizza will go bad, even if you put it back in the freezer. Similarly, when you buy frozen pizza packages and leave them at room temperature for several days, your pizza might not be safe to consume anymore.
As the name suggests, frozen pizzas should be in the freezer. You should store them immediately after bringing them home from the store. Some people are afraid of freezer burn, so they store their frozen pizzas in the fridge.
But doing so will shorten the shelf life of your pizzas very much since the fridge can’t provide the freezing temperature they require. The fridge can be a temporary measure, but never the best place for storing frozen pizzas.
Keep in mind that the more abundant and complex ingredients on the pizza, the shorter its shelf life in the fridge is. Meat and sauce can go off quickly without freezing. After all, it’s got the name frozen pizza – not cold pizza – for a good reason, right?

Storing Frozen Pizzas In The Fridge
In case your freezer is stuffed, it’s not harmful to store frozen pizzas in the fridge for a few days. Storing them there longer than that will cause them to go bad. But if the packages say, “Do not thaw”, “Keep frozen”, or “Do not refrigerate”, the freezer is the only option.
Your fridge is a great temporary stop for your frozen pizza but not a reliable place for long-term storage at all. Your frozen pizzas can only last for 2-3 days in the fridge at 7°F (2.8°C). After that time, your pizza will begin to deteriorate.

Don’t Bake More Pizzas Than You Need
If you go home with more pizzas than you need to eat right away, you should take out or cut up the pizza as you need and refreeze the rest within a few minutes. Otherwise, refreezing the leftovers will likely cause them to have freezer burn and even spoilage.

Signs That Your Frozen Pizza Has Gone Bad
There are tell-tale signs for you to know it’s time to dispose of your pizza. They indicate that your frozen pizzas are no longer safe to consume and should be in your trash bin.
Most spoiled foods come with unpleasant smells. However, frozen foods don’t smell much in a frozen condition, so you will need to thaw them a bit to realize those smells.
Frozen pizzas contain meat, sauce, cheese, and crust. The bad smells come from either of those ingredients. Even if only the meat is off, you should dispose of the whole pizza. Never risk poisoning yourself with potentially spoiled foods.
If your pizza has suspicious spots or a change of colors from ingredients, it may have gone bad. Trust your eyes: the unusual colors are usually a sure sign of spoilage.
Molds don’t always appear in frozen foods, but it’s not impossible. This happens due to some malfunction of your freezer or the pizza has been thawed and refrozen a couple of times.
Mold is tiny black or green spots on the surface of the food. It tells you that bad bacteria have severely infected your pizza. A moldy pizza is the last thing you want to eat since it can lead to fatal food poisoning.
If a portion of food feels slimy to touch when it’s not supposed to, it is no longer edible. Frozen foods rarely get slimy, but some mistakes in storage can make that happen. Pizzas with slimy texture ingredients, such as cheese, meat, or crust, are not safe to eat anymore.
In case you miss all of the above signs and proceed to heat your pizza, the foul taste in the first bite is the final red flag telling you to get rid of the pizza. Another situation is that the crust and other ingredients have turned bland and tasteless.
Always trust your senses. It’s not worth putting yourself through all the risk just for a potentially spoiled pizza.
