  2. Home canning - Wikipedia

    en.wikipedia.org/wiki/Home_canning

    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 ...

  3. Pascalization - Wikipedia

    en.wikipedia.org/wiki/Pascalization

    The experiments were performed up to 1.6 GPa (232,000 psi) of pressure, which is more than 16,000 times normal air pressure, or about 14 times the pressure in the Mariana Trench, the deepest ocean trench. The experiment began by depositing an Escherichia coli and Shewanella oneidensis film in a diamond anvil cell (DAC). The pressure was then ...

  4. Canning - Wikipedia

    en.wikipedia.org/wiki/Canning

    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]

  5. Food storage - Wikipedia

    en.wikipedia.org/wiki/Food_storage

    There are also safety guidelines available for the correct methods of home canning of food. For example, there are specific boiling times that apply depending upon whether pressure canning or waterbath canning is being used in the process. These safety guidelines are intended to reduce the growth of mold and bacteria and the threat of ...

  6. Pressure cooker - Wikipedia

    en.wikipedia.org/wiki/Pressure_cooker

    A stovetop pressure cooker. 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.

  7. Orders of magnitude (pressure) - Wikipedia

    en.wikipedia.org/wiki/Orders_of_magnitude_(pressure)

    Pressure exerted by a 45 kg person wearing stiletto heels when a heel hits the floor [69] 15.5 Mpa 2,250 psi Primary coolant loop of a pressurized water reactor: 20 MPa 2,900 psi Typical pressure used for hydrogenolysis reactions [70] 21 MPa 3,000 psi Pressure of a typical aluminium scuba tank of pressurized air (210 bar) [71] 21 MPa 3,000 psi

  8. Double seam - Wikipedia

    en.wikipedia.org/wiki/Double_seam

    A double seam is a canning process for sealing a tin can by mechanically interlocking the can body and a can end (or lid). Originally, the can end was soldered or welded onto the can body after the can was filled. [1] However, this introduced a variety of issues, such as foreign contaminants (including lead and other harmful heavy metals).

  9. Pascal's law - Wikipedia

    en.wikipedia.org/wiki/Pascal's_law

    Pressure in water and air. Pascal's law applies for fluids. Pascal's principle is defined as: A change in pressure at any point in an enclosed incompressible fluid at rest is transmitted equally and undiminished to all points in all directions throughout the fluid, and the force due to the pressure acts at right angles to the enclosing walls.
