Modeling Mass Transfer During Salting of Catfish Sheets

Abstract

Application of the Peleg and Zugarramurdi and Lupín models in the pile salting of catfish sheets was studied to determine the kinetics of the process. Groups of sheets were salted using different mixtures of NaCl, KCl, CaCl 2 , and MgCl 2 . Initial and final mass, moisture, and salt contents were measured for 6 days. Linear and nonlinear regressions were used to fit a database to Peleg and Zugarramurdi and Lupín models, respectively. The models as fitted explained 99.3-99.8% of the moisture content variation kinetics, and 99.2-99.8% of the salt content variation kinetics.

Determination of transport properties and mechanistic modeling of the coupled salt and water transport during osmotic dehydration of salmon induced by dry salting

“…The model uses dry basis concentrations, and as already mentioned, considers salt and water transport as independent phenomena. This model has been recently applied to sardines (Bellagha, Sahli, Farhat, Kechaou, & Glenza, 2007), anchovies (Czerner & Yeannes, 2013), as well as catfish (Corzo, Bracho, & Rodriguez, 2015) among others. This semi/empirical category includes other approaches that have been applied to cod, such as Gallart-Jornet et al (2007) and Barat, Rodríguez-Barona, Andrés, and Ibáñez (2006).…”
