However, the relationship between Aw and % H2O for 26 commercials samples, ranging in water content from 27.2 to 52.0%, was ambiguous. 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. Mix the salted fish into the mince. ... Salted Fish . 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. Summary. 1. Moisture contents of various grades of salted cod were determined directly by the standard oven method and Compu-Trac™ procedures. Dry salted mackerel, fully split and salted in 1 : 6 ratio were employed for storage study. 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. In addition, fish may be dried without salting; examples are trigger fish (Balistes forcipatus), anchovy (Engranlis encrasicholus), and herring (Sardinella aurita). 15% by weight of the salted fish which has been dried to a moisture content of not more than 16%. Salt helps meat retain moisture, which gives the ground pork a chance to hold onto water better. The salt and fish were layered alternatively to the top and were stored at 10-15°C for six to seven months. 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. R.H. together with the V per cent. Cod is often preserved in salt using a 20% brine solution. Fish proximate composition including the determination of moisture percentage, ash percentage, oil percentage and protein percentage. 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. We use cookies to help provide and enhance our service and tailor content and ads. Moisture content differences could be due to certain factors such as genetic makeup, feed intake, metabolic efficiency, size, sex, and season of the year. Iyengar, J. R. and Sen, D. P. The samples were taken from different area in Indonesia (Cilacap, Palembang, and Sulawesi). Tabulated results show that the equilibrium moisture content depends upon the quality of salt used. 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. The corresponding figure for MgCl2.6H2O was 3.2% (as MgCl2, 1.5%). A drying of unsalted and salted fish slabs are shown in similar effect of air temperature on moisture content was Fig. 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. 17-19.pdf, Food Sci. Among others, this regulation listed denominations for different salted fish cuttings, unacceptable defects, and sampling and microbiological criteria to be applied by custom authorities. Present address: Institute of Marine Resources, Aquaculture and Fisheries Program, Department of Food Science & Technology, University of California, Davis, CA 95616. 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. Salted fish (sand or tin) and brines were collected from various shops to determine keeping quality. 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. The study was conducted to evaluate the chemical and microbiological properties of salted and fresh Inci Kefali (Chalcalburnus tarichi) eaten in eastern Turkey. Copyright (c) 2004-2011 http://ir.cftri.com. Toutefois, la relation entre Aw et % H2O pour 26 échantillons du commerce, avec une teneur en eau variant de 27.2 à 52.0% fut ambiguë. Since most of the dry fish product is from unorganized local manufacturing, compliance to this regulatory standard is unknown. The salted fresh water fish contained 56-57% moisture. Knowing the moisture content of the sample prior to the salt analysis will improve the accuracy of determining dilution factors. 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%. The variable salt content of commercial fish was largely responsible for the lack of correlation between Aw and moisture content. Copyright © 1987 Elsevier Ltd. All rights reserved. A predictive approach was also tested using data collected with a Hygrodynamics water activity meter. 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%. 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. Analar reagents were used for salting. This clearly reveals the fact that the moisture content does not substantially decrease with the delay of processing. The moisture content of delayed fish wet salted in 10 to 33% brine, did not decrease. To achieve a final, safe moisture content of approximately 0.69g H Dried fish products used were: fish cracker, dried-salted fish, ikan kayu (katsuobushi), fufu (very dried-smoked fish) and dried pempek. Evaluation of Methods for Determination of Moisture Content of Heavy Saltd Cod. 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.
