Cook-freeze is another catering system based on full cooking followed by fast freezing and storage at controlled low temperature conditions well below freezing point(-18°C or below). As long. as this storage temperature is maintained, micro-organisms cannot grow. This is subsequently followed by thorough re- heating close to the consumer before prompt consumption. The food should reach a centre temperature of at least-5oC within 90 minutes of entering the freezer and subsequently should reach a storage temperature of-18 C-The shelf-life of pre-cooked frozen food varies according to the type of food but in general it maybe stored for up to 8 weeks without any significant loss of nutrients or palatability. After that time rancidity may develop in foods with a high fat content, but other foods can be satisfactorily stored for longer periods. addition, clear system of coding the containers with product identification, batch production, and expiry dates should be used so that stock can be rotated on a first-in/first-out basis.
