Appertization is also known as what process?

Appertization refers specifically to the method of preserving food through canning. This process involves placing food in jars or cans, sealing them, and then heating to destroy microorganisms that can spoil the food. The name "Appertization" is derived from the inventor Nicolas Appert, who developed this method in the early 19th century as a way to extend the shelf life of food.

In contrast, freezing is a process that preserves food by lowering the temperature to inhibit microbial growth, while drying removes moisture from food to prevent spoilage. Fermentation is a metabolic process that converts sugar to acids, gases, or alcohol, and is used to preserve foods but is significantly different in mechanism and purpose from canning. Thus, the connection of Appertization to canning is fundamental in the context of food preservation techniques.
