Osmotic Dehydration Dynamic of Common Carp ( Cyprinus carpio ) Fillets Using Binary and Ternary Solutions

Abstract

In this work, water activity (aw), moisture loss, and salt uptake as mass transfer in osmotic dehydration (OD) of Cyprinus carpio fillets were analyzed. Two highly concentrated solutions were used for the OD: binary (NaCl-water) and ternary (NaCl-sucrose-water) solutions at 20◦C. Both solutions had the same NaCl concentration, but the second also had sucrose (2:1) which improved water loss and reduced NaCl gain. Among the OD models analyzed, Peleg’s equation presented the best fit with the ternary solution (R2 > 0.900), while the Zugarramurdi and Lupín did so for the binary solution treatment (R2 > 0.950). Page’s model presented good fit for water release in both cases (R2 > 0.950).
