Polyelectrolyte complexes of sodium alginate and gelatin obtained from cold-blooded fish were studied for potential application as structure-forming agents in food hydrogels. The mass ratio of sodium alginate to gelatin plays a decisive role in the sol-gel transition and rheological behavior of the complexes. Differences in the sol-gel transition temperature were observed upon heating and

Polymer rheology testing is the study of how the stress in a material or force applied is related to deformation and flow of the material. Understanding the rheological properties of polymers through laboratory testing can help to optimize products and process conditions, thereby saving costs and minimizing potential waste. Polymers show complex rheological behavior which needs to be considered when using or producing these kinds of materials, like the viscosity of the melt, flow behavior, viscoelastic properties, temperature-dependent behavior, glass transition temperature, aging behavior, etc. Various tests and analysis methods are employed to optimize the Polymer Behavior Larson, Ron, The Structure and Rheology of Complex Fluids (Oxford, 1999) Ferry, John, Viscoelastic Properties of Polymers (Wiley, 1980) Descriptive Rheology Barnes, H., J. Hutton, and K. Walters, An Introduction to Rheology (Elsevier, 1989) Suspension Behavior Larson, Ron, The Structure and Rheology of Complex Fluids (Oxford, 1999) The rheological properties of filled polymers are determined not only by the type and amount of filler, but also by the shape, size and size distribution of its particles. The viscosity of filled systems generally increases with increasing filler fraction.
