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]
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 ...
Food is processed in Weck jars using the water bath canning technique, not a pressure canner. During the canning process the lids are secured by the clips which must be removed once the processing is complete and the jars have cooled. A correctly sealed jar is indicated when the tab of the rubber seal points downward.
However, glass containers presented problems for transportation. Shortly after, the British inventor and merchant Peter Durand patented his own method, this time in a tin can, creating the modern-day process of canning foods. [5] Canning was used in the 1830s in Scotland to keep fish fresh until it could be marketed.
John Landis Mason, inventor of the Mason jar. In 1858, a Vineland, New Jersey, tinsmith named John Landis Mason (1832–1902) invented and patented a screw threaded glass jar or bottle that became known as the Mason jar (U.S. Patent No. 22,186.) [1] [2] From 1857, when it was first patented, to the present, Mason jars have had hundreds of variations in shape and cap design. [8]
For five years, Andrews allegedly treated Jones using air baths, a treatment where the patient would spend a period of time in a tank full of compressed air. [3] 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 ...
Canning involves cooking food, sealing it in sterilized cans or jars, and boiling the containers to kill or weaken any remaining bacteria as a form of sterilization. It was invented by the French confectioner Nicolas Appert. [4] By 1806, this process was used by the French Navy to preserve meat, fruit, vegetables, and even milk.
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).
