An autoclave, also known as a canned food sterilization machine, is used for canned foods where it uses high-pressure steam to remove any dangerous microorganisms & bacteria. The process involves placing food in sealed cans before putting them inside autoclave chambers. As the machine gets heated up, steam comes out, increasing internal pressure & temperature. This effectively kills harmful agents, thus making it fit for human consumption while prolonging its life span. To achieve necessary temperatures around 240°F (this apparatus ensures 116°C) or higher, thorough sterilization is also an indispensable tool in home canning and commercial food processing.
Understanding the Basics of Food Sterilization
Food sterilization is a necessary process that removes all forms of life on food products, such as bacteria, viruses and spores, to make them safe. This can be done using several methods, but heating is the most common. Usually, sterilization involves exposing foods to high temperatures for some time to kill pathogens and spoilage organisms, among others.
