Modern processors maintain close watch on the heating process, ensuring that the canned food that reaches the market is the safest possible product for the consumer.
Why is canned food packed at peak?
Because canned food is packed at the peak of harvest, it also is packed at its nutrient peak. As foods age, they begin to shed some of their essential nutrients.

According to a 1997 University of Illinois study and other recent studies, the canning process actually may help to enhance the nutrient profile of certain foods. Canned pumpkin, for example, contains 540% of the Recommended Daily Intake of vitamin A, while the same amount of fresh pumpkin has only 26%.
