All of us purchase food from the market. Some of us also grow food at home.

While purchasing food we pick and choose from a variety of foods that are sold in the market. Some are cheap, some expensive, some are fresh and some state, some stale, some are in season and some are out of season. All these factors influence our choice of food while buying.

  • ‘Perishable’ is a term used in the context of food that goes bad quickly. For example, if you keep the milk at room temperature, especially in hot summer, by evening it curdles. Bread will show signs of decay in probably 2-3 days times and apples with take even longer. Pulses usually do not show any damage for months.

  • Thus, you can use three different terms to describe perishability of food. These are perishable, semi-perishable and non-perishable. The terms are relative meaning thereby, that all foods are perishable, but some perish much sooner than the others. You must know that each food stuff has a specific period after which it begins to spoil. This period is called shelf life. Depending upon the shelf life we can divide foods into three categories.

  • Perishable foods can be stored for 1-2 days.

  • Semi-perishable foods can be stored for some weeks to 1-2 months.

  • Non-perishable foods can be stored longer as compared to perishables and semi-perishables.
