Although heat-based preservation methods like canning and pasteurization are a staple of our modern society, there are also ways to preserve foods that don’t require heat. If you’ve eaten cheese, kimchi or freeze-dried strawberries you’ve had these types of food.
Preservation seeks to keep food safe, nutritious and tasty for extended periods of time. There are several ways to do this, but the most common methods are based on the following principles:
- Keep it alive (or culture it with friendly microbes)
- Cool it down
- Remove the water
- Remove the oxygen
- Reduce the pH (make it sour/acidic)
- Kill all living things (with heat, chemicals and/or pressure)
On this site, we will explore both contemporary and traditional ways to preserve food. Some will use heat while others will not. All of them can be done off-grid.
Congratulations on making it all the way to the end!
Nearly all cooking methods are based on the principles and methods discussed on this page. Let’s get cooking!
