Accompanying Notes

Describes the changes that can occur in cold storage, the effects of time and temperature on the protein, fat and water content of frozen fish, the factors limiting storage life, and emphasises the need to store frozen fish and products at -30C. Gives a table of examples of storage life of various products at various storage temperatures. Provides some background information on cold store design and notes the basic principles for cold store operation. In modern stores, access is by automatic sliding door controlled remotely, usually protected by a curtain of overlapping, vertical, heavy-duty plastic strips hung across the doorway to reduce the exchange of air when the door is opened, without impeding entry. This Note should be read in conjunction with Note 27. Notes 61 and 90 provide detailed information on factors affecting gaping. Measurements are given in British units; Note 40 gives conversion factors to SI units.
