   ice crystal may vary with method of freezing i.e. quick freezing or slow freezing. Quick freezing is defined as the process where the temperature of the food passes through the zone of ice crystal formation in 10 minutes or less. The process removes quick removal of water and small ice crystals are formed in it.

   What is the difference between quick freezing and slow freezing?

   • Your answer should include the following points: Quick freezing: It is defined as the process where the food passes through the zone of maximum ice crystal formation in 10 minutes or less, whereas, in slow freezing the process may take 3-72 hrs depending upon the commodity. The process involves slow removal of water, may take 3-72 hrs.

   When did quick freezing start?

   • “Quick freezing” as we know it today was started in the US in the early 1920s. Although a high rate of freezing is important for the quality of frozen foods, the temperature at which a frozen product is held after freezing is more important than the temperature to which it is brought during freezing.

   What is freezing process?

   • The temperature of the food undergoing freezing remains relatively constant until the food is mostly frozen, after which time the temperature approaches that of freezing medium. The freezing process is thus a process of lowering of the product temperature from its original value to the storage temperature.

   What are the different methods of freezing food?

   • There are three recognized methods of freezing foods: fast or quick freezing, sharp freezing, and slow freezing. There is no generally accepted definition for differentiating among the various freezing rates. It is obvious that with some methods, such as for food frozen in bulk, the product is frozen slowly.

   How can quick freezing be handled at the industrial level?

   • Quick freezing can be handled at the industrial level because it involves specialized freezing equipment, technological know-how, strict quality control which would not be feasible on a small scale. Sales markets have to be established in all markets with refrigerated display cabinets.

   Is the freezing process Gov-erned?

   • The freezing process is assumed to be gov-erned principally by heat transfer. Numerical calculations have shown that this is generally a valid assumption (Pham 1989) but there are exceptions. Phase change is usually not the only physical phenomenon that occurs in food freezing.
