Why Are Foods Non-perishable. Many processed foods have long shelf lives because they contain chemicals or unnatural ingredients that prolong their shelf life. That means that if the food requires refrigeration either before or after opening it is not a non-perishable item.
Non-perishable foods are the ones with longer shelf lives and which dont require a fridge. In comparison the NHS defines processed foods as those that have been altered in some way during preparation. Examples of foods that must be kept refrigerated for safety include meat poultry fish dairy products and all cooked leftovers.
Why Do You Need Non-Perishable Foods.
Some fresh foods such as potatoes and corn can also be considered non-perishable because they last so long. These non-perishable food items or close to it have lengthy expiration dates so you can stash them away for long periods of time even if its not hurricane season or tornado season. Perishable foods are those likely to spoil decay or become unsafe to consume if not kept refrigerated at 40 F or below or frozen at 0 F or below. A non-perishable food is one that doesnt need to be refrigerated or frozen and that has a long shelf life when compared to other foods.
