How long will things last once the can has been opened?
Once than can is opened, the special nitrogen atmosphere is gone and the food is exposed to humidity, the foods will last as long as similar grocery store products. This means pasta and grains will last months while dairy products should be consumer more quickly. We recommend that once you have opened a can of dried apples, for example, that you use the apples up before you go and open a can of peaches. Of course, if you have a large family or group that consumes large amounts of food, this is probably not necessary. On the other hand, if you are a single person and only eat eggs occasionally, you might want to buy eggs in the #2-1/2 can instead of the #10.
