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 ]
The flammable range of ammonia in dry air is 15.15–27.35% and in 100% relative humidity air is 15.95–26.55%. [42] [clarification needed] For studying the kinetics of ammonia combustion, knowledge of a detailed reliable reaction mechanism is required, but this has been challenging to obtain. [43]
Pressure canning is the only safe home canning method for meats and low-acid foods. This method uses a pressure canner — similar to, but heavier than, a pressure cooker. A small amount of water is placed in the pressure canner and it is turned to steam, which without pressure would be 212 °F (100 °C), but under pressure is raised to 240 °F ...
Different food preservation methods have different impacts on the quality of the food and food systems. Some traditional methods of preserving food have been shown to have a lower energy input and carbon footprint compared to modern methods. [3] [2] Some methods of food preservation are also known to create carcinogens.
In 1872, Jones developed a vacuum canning process for preserving food, with the help of Professor Leroy C. Cooley of Albany, who was the brother-in-law of her sister Emily. At the time, food safety and preservation was only beginning to be understood. While canning food had been relatively popular for European militaries, the system had its ...

Intermediate moisture foods (IMF) are shelf-stable products that have water activities of 0.6-0.85, with a moisture content ranging from 15% - 40% and are edible without rehydration. [1] These food products are below the minimum water activity for most bacteria (0.90), but are susceptible to yeast and mold growth.
