The length of time depends on the expiration date, types of hummus, whether or not it’s shelf-stable hummus, if it is unopened hummus and if its stored at a low temperature. Even the ingredients it’s made with can influence how long it will last.
Unrefrigerated Hummus has a long shelf life. It can last up to 1 month in the pantry if it is kept in a cool dark place. If it’s been exposed to direct sunlight or if the pantry is hot it won’t last as long. It will last up to 1 week in the refrigerator after it has been opened.
