Marine mussels attach to substrates using adhesive proteins. It has been suggested that complex coacervation (liquid-liquid phase separation via concentration) might be involved in the highly condensed and non-water dispersed adhesion process of mussel adhesive proteins (MAPs). However, as purified natural MAPs are difficult to obtain, it has not been possible to experimentally validate the coa...

Turbidity, dynamic light scattering, and electrophoretic mobility were used to study the effects of added salt on coacervation in the system composed of the strong cationic polymer poly(diallyldimethylammonium chloride) (PDADMAC) and oppositely charged mixed micelles of Triton X-100 (TX100) and sodium dodecyl sulfate (SDS). The phase behavior in the range of ionic strengths from 0.05 to 0.60 M ...

encapsulation of olive oil is an effective method to protect it against environmental deteriorative factors. in this research, olive oil microcapsules were produced by complex coacervation method. the objective was to examine the effect of gelatin and arabic gum as shell materials, lactose as cryprotectant, and different acidification times on microencapsulation efficiency of olive oil. arabic ...

Critical conditions for coacervation of poly(dimethyldiallylammonium chloride) (PDADMAC) with bovine serum albumin were determined as a function of ionic strength, pH, and protein/polyelectrolyte stoichiometry. The resultant phase boundaries, clearly defined with this narrow molecular weight distribution PDADMAC sample, showed nonmonotonic ionic strength dependence, with the pH-induced onset of...

The system comprised of poly(dimethyldially1ammonium chloride) (PDMDAAC) and oppositely charged mixed micelles of Triton X-100 (TXlOO) and sodium dodecylsulfate (SDS) displays several states, including coacervate and various soluble complexes. The phase boundary for the equilibrium between soluble complexes and coacervate (“associative phase separation” according to Piculell and Lindman) for 0....

Coacervation is known to be true microencapsulation because the core material is completely surrounded by a continuous coating of wall material. Coacervation involves interaction between one or many hydrocolloids, particularly between oppositely charged protein and polysaccharide in the same reaction media [1]. The interaction relies on the charges carried by the biopolymers, pH of the coacerva...

The temperature-induced liquid-liquid phase transition (complex coacervation) of a polycation-anionic/nonionic mixed micelle system was examined over a range of macroion concentrations and polycation molecular weights (MW) using turbidimetry and dynamic light scattering (DLS). DLS revealed a progressive increase in complex/aggregate size with temperature up to the phase transition at T(φ), foll...

Polyelectrolyte-colloid coacervation could be viewed as a sub-category of complex coacervation, but is unique in (1) retaining the structure and properties of the colloid, and (2) reducing the heterogeneity and configurational complexity of polyelectrolyte-polyelectrolyte (PE-PE) systems. Interest in protein-polyelectrolyte coacervates arises from preservation of biofunctionality; in addition, ...

this study was aimed at evaluating the flow behavior characteristics of yogurt enriched with fish oil (fo) microcapsules prepared by complex coacervation method. fo was microencapsulated in gelatin-acacia gum coacervates. then, the microcapsules were dried, and yogurt was produced from the milk enriched with microcapsules powder. rheological characteristics (as measured using a rotational visco...
