In addition to that some minerals and microbiological parameters were used to compare the effect of salting on th… L'isotherme de désorption à 5°C pour un seul lot de poisson intact très salé, 50.7% H2O qui fut déshydraté par étapes jusqu'à 11.7% H2O, présenta un tracé hyperbolique typique: (% H2O) = (77.24 × 100 Aw)/(1.82 + 100 Aw) avec un coefficient de détermination de 0.99. Le coefficient de détermination (r2) pour l'analyse de la régression linéaire de la détermination de l'humidité par les deux méthodes fut 0.99 pour l'équation:(%H2O,méthodeàl'étuve)=.96(%H2O,methodeCompu-Trac)+3.3%. A predictive approach was also tested using data collected with a Hygrodynamics water activity meter. In 1971, CFE began producing salted fish under the Cristobal ® brand using a technique known as kenching or dry-salting — a preservation technique dating back to the late 1600s in New England. This clearly reveals the fact that the moisture content does not substantially decrease with the delay of processing. The samples were taken from different area in Indonesia (Cilacap, Palembang, and Sulawesi). Fish proximate composition including the determination of moisture percentage, ash percentage, oil percentage and protein percentage. La teneur en sel de 26 échantillons du commerce de poisson très salé a varié de 37 à 49% des extraits secs totaux. Summary. The salted fresh water fish contained 56-57% moisture. most sensitive to salt and moisture content. Drying of fish in the open sun (Figure 3) may introduce various contaminants into the product. The coefficient of variation for triplicate samples ranged from … Le coefficient de variation (C V) pour la détermination de l'humidité de 47 échantillons a varié de 0.2 à 2.3% avec une moyenne de 0,96% par la méthode à l'étuve et de 0.1 à 1.2% avec une moyenne de 0.63% pour la méthode Compu-Trac. Free water content known as water activity (Aw) is used to determine the ability of water on the destruction process of food.

Salted fish was a common and affordable food item found throughout the Realms10, usually produced in costal regions5, salted fish was sometimes eaten raw3, usually being soaked and cooked, or used as an ingredient in various dishes2. Iyengar, J. R. and Sen, D. P. 15% by weight of the salted fish which has been dried to a moisture content of not more than 16%. The variable salt content of commercial fish was largely responsible for the lack of correlation between Aw and moisture content. In addition, fish may be dried without salting; examples are trigger fish (Balistes forcipatus), anchovy (Engranlis encrasicholus), and herring (Sardinella aurita). The salt and fish were layered alternatively to the top and were stored at 10-15°C for six to seven months. of E. coli,was enumerated by 5 tube MPN method using Fig. We suggest the inclusion of the water activity as a parameter for the evaluation of these products.No comércio mundial de peixes salgados e secos, o Brasil é um dos principais importadores. documented for onion slices by Mazza and Le Maguer The rate of change in moisture content was significantly (1980) and for shark slabs by Mujaffar and Sankat (2005). The fish in the above example, if dried to 50% moisture, would have about 6% WPS (3/53 X 100 = 5.7%). The salt, moisture, and water phase salt (WPS) of the salted rainbow trout samples were successfully eval-uated by the impedance module measured at 50 kHz (Ad R2 > 0.85). Ca and Mg chlorides appear to lower the water holding capacity of salted fish at RH of 10-70%, and the effect of Mg is greater than that of Ca. Journal of Food Science and Technology, 7 (1). One of the popular fish species Clarias lazera(Garmout) was selected for this study. Salted, fermented, or fresh fish may be dried in the sun to reduce the moisture content. In canned anchovies the moisture content after salting decreased from 75.5% to 54%.The loss was accompanied by an increase in salt and ash contents. Smoked and salted fish are a traditional processing that many commercially practiced in centers of fishing activity in Indonesia. R.H. together with the V per cent.
