Effects of Selected Variables on the Extractability of Oils from Coacervate Capsules

Structural analysis of microparticles by confocal laser scanning microscopy

“…The internal structure of the microparticles in these experiments was formed by smaller aggregated oil droplets but showed, however, the same composition. Thus, this supports the hypothesis that phase separation takes place by electrostatic interaction of the oppositely charged polymers [16]. Due to the charge equivalence of the two polymeric counterions during coacervation, homogeneous distribution of both polymers inside the particle should be observed, which was supported by CLSM revealing a homogeneous distribution of the labeled polymers.…”

Pectin-Gelatin Complex Coacervates I: Determinants of Microglobule Size, Morphology, and Recovery as Water-Dispersible Powders

“…Some results of this exploratory phase are summarized in Table I. As reported previously (14), mixing of isohydric solutions (pH [3][4] does not change tbe system pH significantly, a fact demonstrated in this study but also one that The mean globule size increased from 2 to 10 pm as the mixing pH was increased from 7-10 (Table I).…”

“…The complex ionic relations of the gelatin-acacia coacervate system have been established and reported previously ( [1][2][3] and have been used successfully in the microencapsulation of solids as well as liquids (4)(5)(6)(7)(8)(9)(10). Until recently (91, it was difficult to control the morphological characteristics of and recover a free-flowing powder of unagglomerated microglobules which were spontaneously dispersible in aqueous solutions.…”

Microspheres: A Review

“…The process is based on the principle of decreasing the solubility of the polymer in the organic phase to affect the formation of the polymer rich phase called the coacervates. [21] The Thiamine mono nitrate and sulpha-ethyl-thi-dizole are encapsulated in a mixture of monoand glycerides of stearic acid and palmitic acid using spray congealing. [22] Very rapid solvent evaporation, however leads to the formation of porous micro particles.…”
