Methods of Food Preservation

There are several methods of food preservation, each with its advantages and disadvantages. Here are some of the most common methods:

This method is suitable for preserving meat, fish, vegetables, and fruits. The downside is that it requires a freezer and can cause changes in texture and flavor.

  3. Drying: Drying involves removing moisture from food, which slows down the growth of bacteria and other microorganisms. This method is suitable for preserving fruits, vegetables, and herbs. The downside is that it can be time-consuming and requires specialized equipment.
