The design, operation, and choice of sterilizing and pasteurization systems, known as retorts, Canning is the process of placing food in a container and hermetically sealing it so that is airtight and impervious to the entrance of microorganisms and then giving it a thermal process has been practiced since around One of the key components that affect the sterilization of the canned products is temperature, which is easily regulated Thermal sterilization has been used to achieve long-term shelf stability for canned foods and is now used for a broad range of products. One of the more severe thermal food processes is referred to as commercial sterilization. The majority of shelf-stable foods are thermally Thermal food sterilization and pasteurization are the most widespread preservation technologies to extend food shelf life by inactivating microorganisms and enzymes that can deteriorate foodstuffs. The application of heat as a preservation method dates back to the nineteenth century, with the ‘appertization’ process developed by Nicolas COMMERCIAL STERILIZATION. Traditionally, this process has been used to achieve long-term shelf stability for canned foods and is now used for a broad range of prod ucts This chapter introduces the reader to the wide array of food process machinery, equipment, and systems that are used throughout the food industry for the purpose of manufacturing shelf-stable foods that are preserved by heat sterilization (thermal processing) Traditionally, this process has been used to achieve long-term shelf stability for canned Chapter Thermal Food Processing EquipmentIntroduction. Sterilization of foods is normally accomplished by what is commonly called ‘canning’ to preserve the safety and wholesomeness of ready-to-eat foods over long terms of STERILIZATION One of the more severe thermal food processes is referred to as commercial sterilization. Traditionally, this process has been used to achieve long-term For this purpose, high-pressure thermal sterilization (HPTS) and ohmic heating (OH) are two promising technologies focused on lowering the processing time through a faster One of the more severe thermal food processes is referred to as commercial sterilization.
