What are the differences between canning and freezing?

Canning and freezing are two different methods of food canning, and the difference is in the process in which foods are preserved for future use. Preservation includes the use of canning containers that are generally stored in a cold and dry place, while foods that are frozen are placed in the freezer safe and stored in the freezer. Preservation and freezing are acceptable methods of preserving homemade food. Preservation is a more viable choice because foods generally have a longer life and do not spoil during the power failure, while freezing is the preferred choice before canning due to the amount of time and steps involved in the preservation process.

Home canning is a method of food protection for more than a century. Canning meals were invented by French inventor Nicolas Appett, during the early 18th century it was a complex process of perfect.

Soon after the invention of Appert, Peter Durand developed a food canning method in metal cans. Only certain types of foods are able to be maintained by this approach, which is often referred to as water canning. For foods with low acid content such as meat, the pressure canning method is recommended.

Clarence Birdseye was credited with the invention of rapid freezing, a technique in which most foods are preserved at home today. Although the process of frosting food was used before the Birdsey method, the way it stiffened food has eliminated some problems they encountered during older methods. Birday's technique included "quick" freezing and preliminary packaging of food, eliminating the problem of ice crystals. Mrowning the food in modern kitchen includes the location of fresh food in a container safe and placed in the frostničky. The correct packaging is the key to preventing the quality of food quality during storage, as damage commonly known as the "burning of the freezer" can occur when food comes into contact with the air circulating in the freezer.

The choice between canning and freezing often depends on the type of food to be preserved and how long the food will be stored. In general, foods such as boiled meat can be stored in the freezer for two to three months, while properly preserved meat will maintain two or more years. Preservation and freezing also differ in the long -term food quality after preservation. The taste of food may deteriorate the longer the frozen; However, canned food often maintains the same flavors throughout their storage life.
