To can green beans, prepare them in advance, choose between hot and cold packs, and know how long they stay fresh. Wash and trim the beans before placing them in the can, and choose the preferred length. Cold packs take less time, while hot packs are ready to eat. Properly stored green beans last up to 18 months, and jars with loose lids should not be used.
Some of the best tips for canning green beans are to prepare them completely in advance, choose between hot and cold packs, and know how long the food stays fresh. Preparing green beans for canning by washing and cutting them to a preferred size gets them ready for dinner months or even years later. Choosing between hot and cold packing is a fairly important decision that can increase or decrease canning and cooking times. Also, knowing how long green beans stay fresh when canned can help you avoid eating spoiled or stale food. Finally, whether it’s canning green beans or other foods, it’s important to know when the can is unsealed.
When storing green beans, the beans should be washed and trimmed before placing them in the can. The length can be any length preferred by the cook, as long as it fits in the can. These steps are for convenience, since washing and cutting them will be more difficult when they are no longer fresh. Plus, many people would rather have their green beans ready-to-go for dinner than completely unprepared.
Green beans can be cold or hot packed in cans. Cold packs are sometimes called raw wraps because the green beans stay raw. Hot packs involve boiling the green beans before canning, which makes them a little more like store-bought canned goods. Cold packs usually take less time than hot packs, although hot packs are practically ready to eat, which also cuts down on the time afterwards.
Properly stored green beans usually keep up to 18 months in a cool, dry place. After 12-18 months, the quality of food can deteriorate significantly. However, experts estimate canned foods are safe to eat for about five years after canning, as long as they haven’t been exposed to extreme temperature changes.
Any jar with a loose or protruding lid will not seal properly. These jars can be placed in the refrigerator for use right after canning the green beans. Some people process the can again, while others are wary of doing so because it may introduce contaminants or the green beans may not last as long as others that have been properly canned. It’s important to check the seals after the jars have completely cooled, and not to twist the caps too much as that too can break the seal.
