Radiation Preservation of Fish and Fishery Products.

RADIATION PRESERVATION OF FISH AND FISHERY PRODUCTS

This text is denoted as No.303 in the Technical Report series issued by the International Atomic Energy Agency in Vienna and represents the final results of a co-ordinated research programme of the joint FAO/IAEA Division of Nuclear Techniques in Food and Agriculture.

Because fish plays such an important role in the diet of the peoples living in South and South-East Asia, it is essential that best use is made of the harvest from the sea. Unfortunately a considerable proportion of the fish is lost owing to insect damage or bacterial onslaught, which makes them inedible. Losses due to poor postharvest techniques have to be made up either by increased production or importing further stock, both cost money which can be a scarce commodity in that part of the world. If radiation preservation could help to reduce the losses then it would be worth doing.

A co-ordinated research programme was therefore begun and Phase 1 of this project was completed as long ago as 1984 but some of the final reports are included in this publication. The actual topics covered in the text are presented as chapters with titles: Semi pilot study on the effects of radurization of dried mackerel (Pneunoatophorous japonicus) for extension of shelf life; Insect disinfection of dried fish products by irradiation; Economic feasibility studies on radiation preservation of dried and cured fishery products, onions and potatoes; Radiation preservation of dried fish indigenous to Asia; Combination of potassium sorbate and irradiation treatments to extend the shelf life of cured fish products; and Radiation disinfestation studies on sun dried fish.

From the above one can see that many aspects of the subject are covered, and the results seem to be positive in most instances but more work needs to be done to establish the economics of the process in the conditions that arise in South and South-East Asia.
