How long is powdered gelatin good for?
If you have unopened dry gelatin packages, they can last up to a year past their expiration date. The expiration date will not affect the gelatin as long as the gelatin is stored away from moisture. An opened packet of gelatin should be used within three months of it being opened to get the best results.
