What is the shelf life of skippy peanut butter when you order it in bulk quanities?
Emulsifiers help to prolong the shelf life of peanut butter. Processed peanut butters like Jif, Skippy, Peter Pan use hydrogenated fat as an emulsifier to to keep the peanuts and oils from separating. Natural peanut butters do not last as long because they do not contain emulsifiers, which is why you have to stir natural peanut butter before using. Peter Pan recommends an 18-month shelf life for their creamy and crunchy peanut butter varieties from the date of manufacture for an unopened container.

Cooler temperatures (except for freezing) will also help to preserve flavor for longer time periods. Here is a link that shows the shelf life of various other shelf-stable foods..
