Sea buckthorn (Hippophae rhamnoides L.) represents a valuable source of biologically active compounds such as carotenoids and polyphenols. High amounts these substances are found in its fruits, bark, leaves. However, their bioavailability is limited must be increased order to benefit from the properties they exert. Therefore, purpose this study was increase stability sea fruit’s bioactives. The...

The aim of this study was to entrap the lipophilic ultraviolet absorber, octyl methoxycinnamate in microcapsuels to enhance its application. A complex coacervation method was established. Through the appearance of encapsulated glass beads prepared with different wall materials, gelatin and sodium polyphosphate were selected as wall materials because of dense structure and less adhesion. The eff...

The effect of temperature on the phase behavior of a polycation-anionic/nonionic mixed micelle system, poly(dimethyldiallylammonium chloride)-sodium dodecylsulfate/Triton X-100, was studied over a wide range of surfactant compositions, ionic strengths, and polycation molecular weights using turbidimetry and dynamic light scattering. Soluble complexes become biphasic upon heating through either ...

Complexation of proteins with polyelectrolytes or block copolymers can lead to phase separation to generate a coacervate phase or self-assembly of coacervate core micelles. However, many proteins do not coacervate at conditions near neutral pH and physiological ionic strength. Here, protein supercharging is used to systematically explore the effect of protein charge on the complex coacervation ...

Introduction Coacervation as a technique for producing nanoparticles has many advantages. It involves only aqueous solvents and mild processing conditions and is therefore ideal for maintaining the stability of proteins and peptides. In this study, we examined the formulation of novel nanoparticles using chitosan (CS) in combination with sulfobutyl ether-7-β -cyclodextrin sodium (SB-CD) for del...

In this paper, microcapsules were produced by complex coacervation using gelatin and acacia as wall materials and olive oil as the core substance. Process parameters, such as the dosage of the crosslinker, concentration of the wall materials, pH Value and the ratio between core and wall materials were analyzed in detail. Moreover, crosslinking degree of wall materials was more important in obta...
