Freezing has been successfully employed for the long-term preservation of many foods, some medical and pharmaceutical substances and equipment, providing a significantly extended shelf life. This process involves lowering the product temperature generally to a level that will prevent spoilage and for some food substances to -18 °C or below. For some food substances the physical state is changed when energy is removed by cooling below freezing temperature. The extreme cold simply retards the growth of microorganisms and slows down the chemical changes that affect quality or cause food to spoil. Introduction of cold accumulators in refrigerating machines has become one the modern ways of reducing the cost of refrigeration.
