How to prevent food from spoiling How to prevent food from spoiling

Food spoilage is a common situation in people's lives. After the food is spoiled, it can no longer be eaten and can only be thrown away, which is a waste. So how can we prevent food spoilage? In fact, there are many ways to prevent food spoilage. I will write them down and tell you in a while.

Ways to prevent food from spoiling

1. Low temperature storage method

Low-temperature storage is the most effective way to prevent food spoilage. It can also be divided into freezing and refrigeration. Because low temperature can reduce the activity of food microorganisms and reduce the occurrence of food chemical reactions, it has a significant effect on preventing food spoilage.

2. High temperature sterilization preservation method

High-temperature sterilization is also an important method to prevent food spoilage. Some microorganisms in food can change their structure and lose their activity under the action of high temperature, thus preventing the massive reproduction of microorganisms and causing food spoilage. Commonly used high-temperature sterilization methods in life include pasteurization, high-temperature sterilization and microwave heating sterilization.

3. Dehydration and drying storage method

Dehydrating and drying food is also an important way to prevent food spoilage, because some microorganisms in food need a certain amount of water to reproduce. People remove moisture from food to avoid the reproduction of microorganisms and prevent food from spoiling. Dried goods, dehydrated meat and dehydrated vegetables in daily life all use this method to prevent food spoilage.
