There are many reasons that will encourage you to preserve food. The best thing about saving food for a longer period is that there will be less wastage of food. It’s time to see, why food is spoiled and how you can prevent it.
Reasons for Spoiling of Food
The main reason due to which the preservation of food is important is to prevent enzymes, oxygen and microorganisms from destroying the food. Now, let’s see more details associated with this.
1. Slow Enzymes Reactions
Enzymes are biological catalysts that trigger chemical reactions in nature. They continue to age fruits, vegetables, meat, fish and poultry and it’s a never-ending process.
They destroy the texture, cause color changes in food such as bananas and apples, make milk rancid and can reduce gluten formation in flour.
Food spoilage by enzymes can be stopped by heating or slowed by brining, freezing, or fermentation. Freeze drying is also one of the best ways to preserve food items like fruits, vegetables, meats, and seafood Vegetables and fruits can be blanched and stored at cold temperatures to prevent them from spoiling. Enzymes inhibitors and changing pH can also prevent food from destroying.
2. Due to Oxidation
The fats in the food oxidize or become rancid due to oxygen. It results in undesirable changes such as a change in color, a decrease in nutrients and more.
Due to oxidation, there is an increase in the growth of microorganisms, oxidation of enzymes and oxidized lipids affect fatty portions.
Oxidation can be prevented by storing food in packages, jars, or cans. Another way is to cover the food tightly with plastic and cook it instantly after cutting. If you want to store it in cold or freezer storage, then it is recommended to use impermeable packaging. Heating can also help drive out the air from the food.
3. Diminished Growth of Micro-organism
Microorganisms are present everywhere, but they can’t be seen with the naked eye. Bacteria, yeasts, or mold can destroy the food and also cause serious illness.
They make food unfit to be consumed, it can cause diseases and sometimes even death.
The most effective way to stop the growth of microorganisms is by reducing water activity that is known as drying. When the weather is hot, the chances of food getting spoiled increases. It’s suggested to keep the food in the refrigerator or in a cool atmosphere.
