ketchup in a jar

Ketchup in a Jar.-time on the shelf.

Chemicals and preservatives in ketchup give it a long shelf-life and will ensure that it won’t spoil quickly. Ketchup stored on the shelf will typically hold its quality for several months, and unopened bottles can often last up to a year before they start to lose their flavor. Refrigeration is not necessary, but can extend the shelf-life.
