How to Prevent Food Spoilage Easily [10 Best Ways]

Are you tired of throwing away spoiled food and wasting money? Learn how to prevent food spoilage and save money on your grocery bill. With a few simple techniques and the right storage methods, you can keep your food fresher for longer and reduce your food waste.

Food deterioration is the process by which food products lose their appeal and become unfit for human consumption.

Every year, one-third of the world’s food items intended for human consumption are lost due to food spoilage. Food deterioration is caused by various external variables, including how the food is packaged and stored.

Bacteria and fungi are among the numerous other reasons. Food’s physical and chemical qualities are altered as a result of these causes. 

Food rotting isn’t something that happens by chance. It is a degeneration that occurs as a result of natural processes. 

To truly comprehend how to prevent it, we must first comprehend what causes it in the first place.

Let’s dive right in.

When you don’t take proper precautions, food rotting  occurs at a much faster rate. Food items that are left neglected attract microscopic creatures.

Long-term food preservation is possible using a variety of ancient and modern approaches. While no food can be preserved indefinitely, these approaches allow foods to be kept long after they are produced.

So, here are 10 ways to prevent food spoilage.

1. Store It Right

Dry foods should be stored in a dry, moisture-free environment. This will prevent any moisture from coming into touch with the food, making it an unsuitable habitat for bacteria to develop and multiply.

Perishable items should be kept in the refrigerator at a low temperature. Make sure your refrigerator is no warmer than 38 degrees Fahrenheit by using a thermometer.

Bacteria will not be able to develop on your food as a result of this. Use antioxidants like citric acid before freezing to prevent discoloration of light-colored fruits.

You can also use vapor-proof packing to keep the air out and prevent oxidation.

Speaking of packing, invest in a vacuum packing machine as well. By removing oxygen and so preventing spoiling, you can extend the shelf life of most of your food in plastic containers.

2. Remove Your Spoiled Food

Make a habit of frequently sorting through your refrigerator or pantry and discarding any food that is moldy, spoiled, or has passed its expiration date. This will prevent damaged food from coming into contact with unspoiled food, so preventing further food spoiling.

3. Separate Foods

Ethylene gas is released by ripening fruits like bananas and apples. They may induce food decomposition if stored with items that do not release ethylene gas. 

Be sure to separate refrigerator foods by compartments and to seal each food well.

4. Dry Your Food

To dry your food, use an electronic dehydrator or a low-temperature oven. The moisture will be removed from the food, preventing microorganisms from ruining it.

Foods with low moisture content, such as fruits, can be dried. You can also dry your beef, but this will take a lot longer. This will drastically extend the shelflife of some of your food.

5. Prevent Bacteria Growth by Depriving Them of Oxygen

By vacuum packaging, canning, or smoking foods, you can deprive your food of oxygen, which then prevents bacteria growth.

6. Eat Leftovers

Eat your leftovers to reduce food waste in your household. Keep track of what you have on hand and attempt to include it in your regular meals.

There are plenty of creative ways you can repurpose leftovers, in case you don’t want to keep eating the same thing for many more days. Chicken breast leftovers, for example, can be repurposed into a chicken fried rice recipe, or a chicken salad sandwich. 

The key is to look for easy recipes that will help you prepare your leftovers into a brand new dish.

7. Don't Wash Fresh Produce Before Storing

Because mold thrives in humid areas, washing the produce keeps it moist, which raises the risk of mold formation.

8. Don't Freeze Already Contaminated Food

Food that has already been tainted should not be frozen. Freezing bacteria causes them to go dormant, but it does not kill them. When the food is thawed, it contains a huge amount of bacteria.

9. Keep Track of Food in Your House

Make a list of everything you have in your refrigerator, pantry, and cupboards. Make a list of any food items that must be consumed promptly. This way, you won’t have to worry about storing food for too long, causing it to spoil.

10. Combine Preservation Methods

Consider combining two or more food preservation strategies. Freeze drying, for example, entails freezing, drying, and oxygen deprivation. Canning salted fish necessitates both salting and oxygen restriction. Heating and oxygen deprivation are both involved in canning.

Now, you know exactly how to prevent food spoilage. But, it doesn’t end here. Keep reading.

Why Does Food Spoil?

So, now that we know how to prevent food spoilage, we must first learn how food spoils. This will give us a better understanding of how to prevent it.


These are chemicals that occur naturally in food. They are in charge of the ripening of fruits and vegetables in particular. 

When plants are harvested, or animals are killed, enzyme action in food begins. They accelerate the degradation process, resulting in food deterioration.



Microorganisms cause food deterioration and food-borne diseases. Pathogenic bacteria are the particular microorganism that cause foodborne diseases. 

They thrive at room temperature, but the majority of them die when food is chilled. They can grow in food without changing its appearance, odor, or flavor. 

Molds, yeast, and some bacteria, among other spoilage germs, can develop and multiply in temperatures as low as 40 degrees Fahrenheit. When these grow on food, it produces either looks or smells bad.


When something is exposed to air, it undergoes a process known as oxidation. Oxidation is a chemical reaction that causes unwanted changes in taste, color, flavor, and nutrient content. Food fats turn rancid as a result of it.


Food that is exposed to light loses color and vitamins. The oxidation of lipids in meals is also influenced by light.


The temperature has a significant impact on storage time. At higher temperatures, food deteriorates more quickly. At room temperature, pathogenic germs reproduce even faster.

Food should be stored at low temperatures to slow microbial development, enzymic spoiling, enzymic browning, and oxidation.


To thrive, these living animals require nourishment. As a result, they harm food, particularly the exterior protective layer, allowing bacteria to access the foodstuff much more easily and causing food deterioration.


Humidified storage settings aid the growth of microbes. Food stored in a dry environment is less susceptible to microbial growth and multiplication. Dry conditions are comparably much better for food preservation.


This is an obvious one. To develop, proliferate, and generate toxins, microorganisms require time. Time is also required for oxidation and enzyme action to occur.

Unless you can ensure proper storage, it’s best not to buy huge quantities of perishable goods to prevent germs and bacterium from developing.

Signs of Food Spoilage

Foods contaminated with germs do not have to look, taste, or smell terrible to be harmful.

Foods may contain infectious microorganisms that establish themselves in your intestines and begin reproducing or developing poisons produced by bacteria. 

In the latter situation, the poison is consumed rather than the live microbe.

Here are signs of food spoilage:

  • The food product, especially dairy, begins to emit a noxious smell
  • Deteriorated structure and texture (mushy, slimy, wrinkly) of fruits
  • Bruised fruit meat inside that become discolored and smelly
  • Cheese develops a thin layer of film indicating that it’s gone bad; the same goes for meat
  • Raw meat or cheese that feels soggy or has a sheen on it
  • Apparent presence of mold
  • Bulging cans, lids, and bottles, or broken seals

It is important that you avoid eating spoiled food, as it may cause food poisoning and food safety is low.
