The following video segments offer some specific recommendations for boiling water and pressure canning.

- The boiling water canning process (1.54)

Boiling water canning is recommended for processing acid foods such as fruits and properly acidified tomatoes, pickles, and relishes. This information covers most of the basic steps in managing the boiling water canning process.

- The pressure canning process (1.56)

Pressure canning is the only recommended method for canning low acid foods such as vegetables, meat, poultry and seafood. This information covers most of the basic steps in managing the pressure canning process, including venting air out of the pressure canner before it is brought to pressure.

These next two segments demonstrate hot pack and raw pack steps.  Raw packs do not call for preheating food pieces before they are filled into jars. Hot packing by preparation steps that call for boiling or simmering foods before filling jars is the best way to remove excess air that could lead to color and flavor changes over time during storage.  Hot packs are often preferred for many fruits canned in boiling water.  Hot packs also usually allow you to fit more food into less jar space than raw packs.

- Hot pack for fruits (1.51)

Prepared fruit is heated in water or syrup as described for specific foods prior to filling jars. This information demonstrates the hot pack process for filling jars with peaches.

- Hot pack for vegetables (2.58)

Prepared vegetable pieces are heated in water or other liquid, as described for specific foods prior to filling jars. This information demonstrates the hot pack process for filling jars with green beans.

- Raw pack for vegetables (.52)

Raw prepared vegetable pieces are placed into jars without preheating. The vegetable pieces are then covered with hot or boiling liquid as described for specific foods. This information demonstrates the raw pack process for filling jars with green beans.
