This method is a faster process than dry heat sterilization. Steam sterilization is performed using an autoclave , sometimes called a converter or steam sterilizer. The object or liquid is placed in the autoclave chamber, which is then sealed and heated using pressurized steam to a temperature set point for a defined period of time.
The proper time and temperature for dry heat sterilization is 160 °C (320 °F) for 2 hours or 170 °C (340 °F) for 1 hour, and in the case of High Velocity Hot Air sterilisers, 190°C (375°F) for 6 to 12 minutes. [3] Items should be dry before sterilization since water will interfere with the process.
The most popular cooking method for food prepared using a spice rub is grilling. Baking and pan roasting are other dry-heat methods. Sautéing is another method, especially if the spice rub includes flour or bread crumbs. When water is used for cooking, it is usually after the food has already been partially cooked with the dry heat method.
Dry heat cooking imparts a distinctive richness to foods through the processes of caramelization and surface browning. As heat travels through, it transforms batters and doughs into baked goods and more with a firm dry crust and a softer center. [2]
Roasting is a cooking method that uses dry heat where hot air covers the food, cooking it evenly on all sides with temperatures of at least 150 °C (300 °F) from an open flame, oven, or other heat source. Roasting can enhance the flavor through caramelization and Maillard browning on the surface of the food.
Prevention is primarily by proper food preparation. The toxin, though not the spores, is destroyed by heating it to more than 85 °C (185 °F) for longer than five minutes. The clostridial spores can be destroyed in an autoclave with moist heat (120°C/ 250°F for at least 15 minutes) or dry heat (160°C for 2 hours) or by irradiation.
