Using Pressure Canners
Most modern pressure canners are lightweight, thin-walled kettles; most have screw-on lids fitted with gaskets. Modern pressure canners have removable racks, an automatic vent/cover lock, a vent pipe, and a safety fuse. Use only canners that have the Underwriter’s Laboratory (UL) approval mark to ensure their safety. This publication covers steps to successful food preservation using pressure canners.

An acidified food is a low-acid food to which acids (such as vinegar, lemon juice, citric acid, etc.) or acid foods (such as fruits or tomatoes) have been added to bring the equilibrium pH of the food to 4.6 or less, with equilibrium water activity greater than 0.85.

Using Hot-Fill-Hold: A Thermal Preservation Process. Processors of acidified foods are required to comply with federal, state, and local regulations (when applicable) for thermal processing to ensure the safety and shelf-stability of their products. The hot-fill-hold (HFH) process is a thermal processing technique used to inactivate pathogens and extend the shelf life of acidified products. Heating before filling allows for commercial sterilization of the product, and then filling the container with the hot product will sterilize the clean container.

When processing acidified foods, the hot-fill-hold process involves heating the product to around 180–200 °F, then filling, inverting, and holding for 2–5 minutes to achieve commercial sterility. Higher temperatures will generally correlate with shorter hold times, and lower temperatures will generally correlate with longer hold times.

Making homemade infused cooking oils comes with food safety risks, particularly for those infused with garlic and herbs. Infused oils can enhance flavor and food presentation, but the combination of oil, garlic, and herbs creates an anaerobic (low-oxygen) environment, which is ideal for the growth of the bacteria that causes botulism, which can produce a deadly neurotoxin. The publication provides essential safety tips, such as sterilizing containers and thoroughly washing and drying ingredients, to prevent contamination and ensure safe oil infusion. By following these guidelines, home food preservers can create flavorful infused oils without compromising safety.
