Canning is a method of food preservation in which food is processed and sealed in an airtight container (jars like Mason jars, and steel and tin cans). Canning provides a shelf life that typically ranges from one to five years, [ a ] although under specific circumstances, it can be much longer. [ 2 ]
Aseptic processing works by placing sterilized food (typically by heat, see ultra-high temperature processing) into sterlized packaging material under sterile conditions. The result is a sealed, sterile food product similar to canned food, but depending on the technique used, damage to food quality is typically reduced compared to canned food.
Potted meat is a form of traditional food preservation in which hot cooked meat is placed in a pot, tightly packed to exclude air, and then covered with hot fat. [ 1 ] [ 2 ] As the fat cools, it hardens and forms an airtight seal, preventing some spoilage by airborne bacteria . [ 3 ]
Pascalization, bridgmanization, high pressure processing (HPP) [1] or high hydrostatic pressure (HHP) processing [2] is a method of preserving and sterilizing food, in which a product is processed under very high pressure, leading to the inactivation of certain microorganisms and enzymes in the food. [3]
A pressure cooker is a sealed vessel for cooking food with the use of high pressure steam and water or a water-based liquid, a process called pressure cooking. The high pressure limits boiling and creates higher temperatures not possible at lower pressures, allowing food to be cooked faster than at normal pressure.
