If the cans look okay, they are safe to use. Discard cans that are dented, rusted, or swollen. High-acid canned foods tomatoes, fruits will keep their best quality for 12 to 18 months; low-acid canned foods meats, vegetables for 2 to 5 years.

Most food is still edible after the expiration date. In most food stores, waste is minimized by using stock rotation , which involves moving products with the earliest sell by date from the warehouse to the sales area, and then to the front of the shelf, so that most shoppers will pick them up first and thus they are likely to be sold before the end of their shelf life.

Accelerated shelf-life test (ASLT) methods for processed foods are receiving greater attention. In this paper, current ASLT methodology for fatty foods is reviewed with particular emphasis on the testing of antioxidant effectiveness.

Samples should be inspected and tested for stability of the critical physical and chemical characteristics, as well microbiological testing for both spoilage indicator organisms and the cold-tolerant pathogens, at suitable intervals. Trials should continue beyond the targeted shelf-life, unless the product fails earlier. The following questions should be asked: Does the pH change due to microbial growth or failing buffering systems? Is water redistributed in the product due to condensation or broken emulsion?

Is the preservative system stable?

For much of his career, Dr. Theodore Labuza has focused primarily on the material science of foods and the kinetics of reactions leading to loss of shelf life as a function of moisture content and temperature.

In the 70’s, he was able to demonstrate that the activity of water and not moisture content per se is the controlling factor for degradation in foods.
