Salt helps meat retain moisture, which gives the ground pork a chance to hold onto water better. One of the popular fish species Clarias lazera(Garmout) was selected for this study. Fresh fish samples were taken from Al Mawrada fish market. CaCl2.2H2O was mixed with NaCl at a level of 2.3% (as CaCl2, 1.75%). A drying of unsalted and salted fish slabs are shown in similar effect of air temperature on moisture content was Fig. Analysis of four commercially available brands of salted fish available locally revealed that the moisture content averaged between 0.83 to 0.89 g H 2 O/g DM (44- 47% wet basis) and water activity values 0.786 to 0.789. Smoked and salted fish are a traditional processing that many commercially practiced in centers of fishing activity in Indonesia. The study was conducted to evaluate the chemical and microbiological properties of salted and fresh Inci Kefali (Chalcalburnus tarichi) eaten in eastern Turkey. Iyengar, J. R. and Sen, D. P. The moisture content of these samples ranged from 29.6 to 53.3% as determined by the oven method. Designed and Hosted by Food Science and Technology Information Services (FOSTIS). The fish in the above example, if dried to 50% moisture, would have about 6% WPS (3/53 X 100 = 5.7%). The ratio of common salt to dressed weight of fish was 1:3, and salting was carried out at 21-30 degree C for 48 h. The mackerel was sun-dried to a moisture content of approximate equal to25%. 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. Free water content known as water activity (Aw) is used to determine the ability of water on the destruction process of food. Fish are salted whole (if they are small), split or cut into pieces prior to salting. Les teneurs en humidité de morues salées de diverses catégories ont été déterminées directement par la méthode normalisée à l'étuve et par les procédés Compu-Trac. 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. The salt, moisture, and water phase salt (WPS) of the salted rainbow trout samples were successfully evaluated by the impedance module measured at 50 kHz (AdR2 > 0.85). Journal of Food Science and Technology, 7 (1). La teneur en sel de 26 échantillons du commerce de poisson très salé a varié de 37 à 49% des extraits secs totaux. 1: Moisture content of the sun dried seafoods APHA [32]. The salted fresh water fish contained 56-57% moisture. Wet salted fishes have shortshelf stability with a moisture content of 50-55% and a salt content of around 25%. Powered by Eprints, ePrints@CFTRI supports OAI 2.0 with a base URL of http://ir.cftri.com/cgi/oai2, Journal of Food Science and Technology, VoL 7, March 1970, pp. 3.3.2 Split fish with entire backbone — … R.H. together with the V per cent. RESULTS AND DISCUSSION Moisture: The results of the moisture content of samples is represented in Fig. 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%. This clearly reveals the fact that the moisture content does not substantially decrease with the delay of processing. The fish were placed in petri dishes and left in desiccators EXPERIMENTAL it has been decided to reinvestigate the equilibrium moisture content of salted and dried fish in the critical rr-jge of 70—80 per cent. 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. Dry salted mackerel, fully split and salted in 1 : 6 ratio were employed for storage study. 17-19.pdf, Food Sci. The coefficient of variation for triplicate samples ranged from … 17-19, 13 ref.. Mackerel (Rastrelliger canagurta) and a lean fresh water fish (Barbus carnaticus) were used in a study of the effects of Ca and Mg impurities on the equilibrium RH relationship of salted fish. Among others, this regulation listed denominations for different salted fish cuttings, unacceptable defects, and sampling and microbiological criteria to be applied by custom authorities. For microbiological stability, products cured with impure common salt should be dried more than those cured with pure salt. : = 4.8% 63 3X100 = %Moisture+%Salt %SaltX100 WPS = As indicated WPS is a function of both the level of added salt and the final moisture content.

Canadian Institute of Food Science and Technology Journal, https://doi.org/10.1016/S0315-5463(87)71091-8. The variation of moisture content in the dried fish might be the effect of the different drying methods. This was within the recommended range for fish drying. The salting process and product characteristics are affected by the type of salt used and the duration of the process. Evaluation of Methods for Determination of Moisture Content of Heavy Saltd Cod. In the case of fresh fish the moisture content decreased with the increase of … These observations are in line with the findings of Olayemi et al. Copyright (c) 2004-2011 http://ir.cftri.com. 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. Drying of fish in the open sun (Figure 3) may introduce various contaminants into the product. (1970) The salt content of 26 commercial samples of heavy salt fish ranged from 37 to 49% of the total solids. Knowing the moisture content of the sample prior to the salt analysis will improve the accuracy of determining dilution factors. Moist fish products require By continuing you agree to the use of cookies. Moisture contents of various grades of salted cod were determined directly by the standard oven method and Compu-Trac™ procedures. Copyright © 1987 Elsevier Ltd. All rights reserved. In addition, fish may be dried without salting; examples are trigger fish (Balistes forcipatus), anchovy (Engranlis encrasicholus), and herring (Sardinella aurita). To whom correspondence should be addressed. The salted fresh water fish contained 56-57% moisture. Fish proximate composition including the determination of moisture percentage, ash percentage, oil percentage and protein percentage. For example, fish with 3% salt and 60% moisture would have 4.8% WPS; i.e. ... Salted Fish . who reported that the moisture content of smoked fish reduces during heat treatment which differs with species . La variation de la teneur en sel du poisson salé commercial fut dans une grande mesure responsable pour le manque de corrélation entre Aw et la teneur en humidité. most sensitive to salt and moisture content. The fishes were cleaned, and stored in plastic and wood containers. Equilibrium moisture contents corresponding to RH from 10 to 100% were determined and analytical figures for moisture, fat, ash and NaCl centents are given with methods of analysis. Dried split fish, commonly known as “daing” (split form) is the fish that has been converted from the fresh state to a much lower moisture level with the use of heat with or without salt to maintain its acceptability over an extended period of time.. Salted Dried Split Fish Ingredients: 60 kg Fresh Galunggong 6.5 Kg salt for every 60 Kg of fish 5 gallons of water This type of bacteria was distributed widely in salted fish, dried fish, salt farm samples, crude salt for soy-sauce making, soy-sauce mashes, seasands and seaweeds. The contents of moisture, protein, ash, fat, crude fibre and carbohydrates varied considerably and ranged between 51.0-55.0 %, 18.5-21.5%, 12.9-14.2%, 7.7-8.9%, 0.9-1.8% and 2.6-6.2%, respectively. R With respect to this, the current report has been prepared to analyze Superb quality, consistency and flavor — our four brands of salted fish have become the Gold Standard among connoisseurs.
