STUDY ON SORPTION ISOTHERMS OF SHRIMP BEADS

Sorption isotherms of shrimp heads ( adsorption and desorption ) were analyzed by the microclimate method as temperatures of 30, 45 and 60°C and conditions for shrimp heads conservation by drying were determined. Equilibrium time was reduced from normally 2-3 weeks to only 5-8 days by employing sulf...

Zusammenfassung:Sorption isotherms of shrimp heads ( adsorption and desorption ) were analyzed by the microclimate method as temperatures of 30, 45 and 60°C and conditions for shrimp heads conservation by drying were determined. Equilibrium time was reduced from normally 2-3 weeks to only 5-8 days by employing sulfuric acid at different concentrations and vacuum. The results were adjusted by Henderson and G.A.B. models and correlation coefficients were up to 0.9900 for the last model.
