Packaged cake mixes can turn rancid after the due date, and before the due date if they're not properly stored. They need to be in a cool, dark area.
how long after exsperation date is cake mixes safe to use ?
It is safe to use Duncan Hines cake mixes for several months after it the best if used by date. The cake will likely bake up flatter than usual however.
it means the date that it was packaged
Quite honestly, if you are going to the trouble to make a cake, it is better to make sure that the ingredients for the cake are as fresh as possible (and certainly within their use by date). If you use old fruit the cake will not taste as good as it should do and it may even taste bad (especially with old, rancid nuts).
if you have packaged popcorn past the expiration date, throw it way because if must be at least 3 years old.
Commercially packaged cake mix stays safe to eat long after its expiration date has passed -- up to 12-18 months. It's loaded with preservatives and uses dry milk and egg solids, so it isn't going to go "bad" for a long time. As long as the plastic pouch is unbroken it will taste fine.
Packaged condiments need to be thrown out when they expire. The package should say when the expiration date is or was. When in doubt, throw it out, as they say.
That is not exsact date. The cake shirt will pop up at any random date in the year!!
Packaged pasta has a long shelf life, and does eventually go bad if it goes unused for a long period of time. The only food that has no expiration date is honey.
Depending on the nut peanuts, pecans.... i would stay away from Yes, they can go rancid.
Look for wierd behaviors and such, and check the expiration date just to be sure.
Manufacturers are require to put dates on products, but just because something is past the expiration date does not mean it is spoiled, especially dry, boxed products. You can use an outdated cake mix, but it may have lost color, flavor, and nutritional value. It is unlikely to be harmful. Check the mix for signs of mold or insects. If it looks and smells okay it is most likely safe to use.
