Defines freezing time and explains why it is important. Discusses factors affecting freezing times such as the air speed in a blast freezer, and product temperature, thickness, shape, density, contact area, packaging and water content, and how freezing times can be measured. Notes that estimated freezing times are often inaccurate, and emphasises the importance of measuring actual freezing times during a process, and the significance of errors. Lists measured freezing times for a number of fish products. Read in conjunction with Notes 27 and 94. This Note is relevant to many in this series concerned with aspects of freezing.
