Canning 101 provides an overview of canning along with links to resources and detailed information to help you understand the canning process so you will be informed and ready to embark on this facet of home food preservation.
What is Home Canning?
Canning is a preservation method, where foods are packed in jars and immersed in either a waterbath or pressure canner and heated for a specific amount of time at a certain temperature. The type of food will dictate what type of canner must be used, temperature maintained and the process period that is required.
Canning mason or preserving jars consist of a glass jar, metal band and flat lid. Every part of the canning jar must be in good condition in order to get a good vacuum seal of jar contents and thus preserve the foods for later use.

Processing foods such as fish or meats in metal tins is also a form of home canning, but it requires specialized equipment to apply and seal the metal lids to canning tins. It is more difficult to obtain supplies and equipment for this type of canning and it is therefore not as popular as canning with jars.
Maintaining heat and pressure during the canning process prevents harmful organism and bacterias from causing food spoilage and health concerns. It also cooks the foods and pushes the air from the jars, creating a vacuum seal. When the canning time period has expired, you can safely remove hot jars with a jar lifter to a waiting towel on the counter. Leave air space in between jars and ensure there's no cold drafts in the room. During the cooling-off period, you will hear the lids 'pop' as the seal process is completed. This is a safe airtight sealing of jar contents to preserve the contents. It further protects the canned foods from bacterial growth, deterioration and spoilage.

High acid foods such as fruits, fruit juices, jams, pickles and tomatoes can be processed in a waterbath canner. However, low acid vegetables, meats, fish and poultry must be processed in a regulated pressure canner. Special canning jars that are made of tempered glass should be used with appropriate sealing lids for the canning process.
Certain small canning tools such as funnels, apple corers and cherry pitters are great convenience items, but others like jar lifters, jars, canner racks, timers and tongs are must-have tools for the canning process.
