Complex coacervation in whey protein (WP)/gum arabic (GA) mixtures occurred in a specific pH window between 2.5 and 4.8. After phase separation, a concentrated polymer (also called coacervate) phase was obtained, whose viscoelastic properties were st

We have investigated the linear viscoelastic behavior of guar gum solutions as a function of frequency, temperature, polymer concentration, and molecular weight. This was done to sort out the importance of different relaxation mechanisms like reptati

A new model for the linear viscoelastic behavior of polymer networks is developed. In this model the polymer system is described as a network of spring segments connected via sticky points (as in the Lodge model). [Lodge, A. S., “A network theory o

The interaction of new pectin-modifying enzymes (Novo) with three commercial pectins and their chemically de-O-acetylated and de-esterified counterparts is investigated. The study focuses not only on the ability of these pectins to act as substrates,

To gain more insight into the mechanisms of stress relaxation in aqueous guar gum solutions, we investigated the effect of chemical modifications of the polymer and of the solvent on the linear viscoelastic behavior in different regions of the freque

Guar gum is a linear polymer with associative sites which can connect and disconnect reversibly. Experimental visco-elastic moduli showed two storage modulus plateaus, a broad relaxation spectrum and partial time temperature superposition.

Tlie high-frequency (100 Hz-200 kHz) linear viscoelastic behaviour of gelatin in the transition zone was investigated. During the early stages of ageing, the dynamic shear modulus for a 4 wt% gelatin gel at the gel point at 25 µC was found to vary a

A transient network model is described for a polymeric system consisting of linear chains, connected with temporary cross-links. The model is a reformulation and extension of a similar model which was presented recently [Wientjes, R. H. W.; Jongschaa
