Iyengar, J. R. and Sen, D. P. The salted fresh water fish contained 56-57% moisture. 2a,b, respectively. most sensitive to salt and moisture content. Fresh fish samples were taken from Al Mawrada fish market. The moisture content of delayed fish wet salted in 10 to 33% brine, did not decrease. The salt content of 26 commercial samples of heavy salt fish ranged from 37 to 49% of the total solids. The variable salt content of commercial fish was largely responsible for the lack of correlation between Aw and moisture content. Evaluation of Methods for Determination of Moisture Content of Heavy Saltd Cod. who reported that the moisture content of smoked fish reduces during heat treatment which differs with species . The salting process and product characteristics are affected by the type of salt used and the duration of the process. Present address: Institute of Marine Resources, Aquaculture and Fisheries Program, Department of Food Science & Technology, University of California, Davis, CA 95616. Drying of fish in the open sun (Figure 3) may introduce various contaminants into the product. In addition to that some minerals and microbiological parameters were used to compare the effect of salting on th… The desorption isotherm at 5°C for a single lot of intact heavy salt fish, 50.7% H2O which was stepwise dehydrated to 11.7% H2O, exhibited a typical hyperbolic plot: (% H2O)=77.24×100Aw)/(1.82+100Aw) with a coefficient of determination of 0.99. To achieve a final, safe moisture content of approximately 0.69g H Tabulated results show that the equilibrium moisture content depends upon the quality of salt used. A drying of unsalted and salted fish slabs are shown in similar effect of air temperature on moisture content was Fig. Summary. dried fish products and its water content/water activity to the self life of the products.

Moisture contents of various grades of salted cod were determined directly by the standard oven method and Compu-Trac™ procedures. 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). The moisture content of the 47 heavy salt cod samples analyzed are summarized in Table 1. 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. The temperature and relative humidity inside the greenhouse varied from 32°C to 51.4°C and 24.9% to 58.71%, respectively. Designed and Hosted by Food Science and Technology Information Services (FOSTIS). The samples were taken from different area in Indonesia (Cilacap, Palembang, and Sulawesi). Salt uptake is affected by: Due to rapid and non-destructive analysis coupled with low cost device design, this Moisture content differences could be due to certain factors such as genetic makeup, feed intake, metabolic efficiency, size, sex, and season of the year. The salt and fish were layered alternatively to the top and were stored at 10-15°C for six to seven months. The coefficient of variation for triplicate samples ranged from … Muscles of tin‐salted fish were somewhat more soft and moist (moisture content 60.17%) than sand‐salted (50.5%). This method is particularly suitable for fatty fishes like oil sardine, mackerel etc. For example, fish with 3% salt and 60% moisture would have 4.8% WPS; i.e. of E. coli,was enumerated by 5 tube MPN method using Fig. For microbiological stability, products cured with impure common salt should be dried more than those cured with pure salt. To whom correspondence should be addressed. 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. Since most of the dry fish product is from unorganized local manufacturing, compliance to this regulatory standard is unknown. The equilibrium relative humidity relationship of salted fish (Barbus carnaticus and Rastrelliger canagurta): The effect of calcium and magnesium as impurities in common salt used for curing. 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. The variation of moisture content in the dried fish might be the effect of the different drying methods. 1. In the case of fresh fish the moisture content decreased with the increase of … The pH value ranged between 5.5- 6.3, and energy varied greatly between the various samples (ranged from 385 to 670 kJ). Soak the fish in a concentrated brine solution for 3 to 6 hours to partially extract the moisture content of fish. Salt helps meat retain moisture, which gives the ground pork a chance to hold onto water better. R Among others, this regulation listed denominations for different salted fish cuttings, unacceptable defects, and sampling and microbiological criteria to be applied by custom authorities. Fish are salted whole (if they are small), split or cut into pieces prior to salting. Salting Troughs for Brining Fish 5. ScienceDirect ® is a registered trademark of Elsevier B.V. ScienceDirect ® is a registered trademark of Elsevier B.V. This study was directed towards the study of fish salting and its effect on the nutritive value of fish products. Mix the salted fish into the mince. 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. ... Salted Fish . Comparatively lower amounts of moisture content were observed in the improved and solar-dried products, where fish was soaked in a salt solution that helped to reduce the water activity of the fish … One of the popular fish species Clarias lazera(Garmout) was selected for this study. RESULTS AND DISCUSSION Moisture: The results of the moisture content of samples is represented in Fig. Quantab© procedures for "Solid or Semi-Solid" samples does not consider sample moisture content and uses a one to ten dilution factor which will slightly overstate the salt content of smoked fish. Salted, fermented, or fresh fish may be dried in the sun to reduce the moisture content. 1: Moisture content of the sun dried seafoods APHA [32]. The fish in the above example, if dried to 50% moisture, would have about 6% WPS (3/53 X 100 = 5.7%). Fish proximate composition including the determination of moisture percentage, ash percentage, oil percentage and protein percentage. The coefficient of variation (cv) for moisture determination of 47 samples ranged from 0.2 to 2.3% and averaged 0.96% for the oven method and ranged from 0.1 to 1.2% moisture and averaged 0.63% for the CompuTrac™ method. The higher the fat content, the juicier the patty. 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. Moist fish products require In the first 8 hr of the dying process, a salt concentration of 0.2 g NaCl/g gave the fastest drying rate for both salting methods. By continuing you agree to the use of cookies. R.H. together with the V per cent. The moisture and sodium chloride in the muscles and brines were also determined. CaCl2.2H2O was mixed with NaCl at a level of 2.3% (as CaCl2, 1.75%). At this level of 20% salinity, water is effectively drawn out of any microorganism that will spoil the meat.

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. 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. Les données recueillies à l'aide d'un compteur hydrodynamique de l'activité de l'eau furent utilisées pour vérifier une approche prophétique. Copyright © 2021 Elsevier B.V. or its licensors or contributors. 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%. Journal of Food Science and Technology, 7 (1). The salted fresh water fish contained 56-57% moisture. 3.3.2 Split fish with entire backbone — … & Technol. The moisture content of these samples ranged from 29.6 to 53.3% as determined by the oven method. 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. 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. Analar reagents were used for salting. 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). Among the seven salted and sun dried sea foods Acetessp. 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. With respect to this, the current report has been prepared to analyze 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.
