c::DDE OF PRACTICE OF SALTED FISH
FDR THE EGYPTIAN RED SEA c::DAST
ABSTRACT
Sal ting is one of the methods used for preserving fish. This \vay -was used for so many years ago due to lack of transportation and huge distance between areas of landing fish and tis marketing, due also to lack of ice, and refregeration facilities. Inspite of the technology of preserving fish, the consumer is insisting and demanding salted fish specially during religious and national festivals such as Sham El Nessim and the first day of Bairam.
In these occasions, prices are al-ways higher.
The method of salting fish is different from one place to another, according to the consumers' preference and taste. Sori18 people used to eat salted fish prepared from putrified fresh fish with a little amount of salt, \Vhile others in Upper Egypt used to eat heavily salted fish during sum.mr season to compensate the loss of salt, by sweat, during hard work.
The method of salting fish along the Egyptian Red Sea Coast is done traditionally on board during fishing trips \Vhich may last two to three nnnths near the Sudanese borders mere they fish nullets and salt it.
The quality of salted fish produced in the Egyptian Red Sea reflects:
(i) The absence of technological irr\provements in the processing method, and
(ii) The unhygienic conditions under \Vhich salted fish is produced, stored, transported and marketed.
This code of practice for salting fish have been written as a guiae for the people who works in fish salting industry. It includes the technical guidelines and main practical needs to produce a better quality salted fish.
These guidelines depends on our field observations on the traditional n18thods for handling and processing fish, also on the laboratory analysis of salted fish before marketing. Results shov>'s that it contains high value of fatty acids ( 18 .60 rrg/gr) \Vhich indicates fat rancidity and shmvs also high value of free volatile nitrogen (2.80 rrg/gr) v/nich indicates that salting -was carried out after fish vvas spoiled.
