Studies on the formation of complex coacervates between chitosan and alginate during microparticles preparation
(2005-07-01)
The formation of complex coacervates between chitosan and alginate was evaluated during microparticles formation. Mass ratio between polyelectrolytes and calcium chloride concentration were determinated by conductimetric ...
Production of turmeric oleoresin microcapsules by complex coacervation with gelatin-gum arabic
(2013-06-01)
Turmeric oleoresin is a colorant prepared by solvent extraction of turmeric (Curcuma longa L.). Curcumin, the major pigment present in turmeric, has been described as a potent antioxidant, anti-inflammatory and anticarcinogenic ...
Microencapsulation of ginger oil by complex coacervation using atomization: Effects of polymer ratio and wall material concentration
(2021-02-01)
The objective of this work was to investigate the feasibility of inducing complex coacervation by atomizing an emulsion of gelatin/ginger oil over a gum Arabic solution, which would be a first step towards continuous process ...
Release properties of chemical and enzymatic crosslinked gelatin-gum Arabic microparticles containing a fluorescent probe plus vetiver essential oil

Microspheres of alginate-chitosan containing isoniazid
(Taylor & Francis Ltd, 2003-01-01)
Isoniazid was encapsulated into microspheres of alginate-chitosan by means of a complex coacervation method in an emulsion system. Since the encapsulation of isoniazid tends to be limited by its hydrophilic characteristics, ...
Particle size characteristics of buriti oil microcapsules produced by gelatin-sodium alginate complex coacervation: Effect of stirring speed
(2017-12-29)
The influence of hydrodynamic conditions in the coacervation medium of the carotenoid-rich buriti oil using gelatin-alginate as wall materials was investigated. The stirring speed had strong influence on the size of the ...
Use of a tubular heat exchanger to achieve complex coacervation in a semi-continuous process: Effects of capsules curing temperature and shear rate
(2021-12-01)
The main objective of this study was to convert the cure of the capsules produced by complex coacervation in a continuous process. To achieve this, a continuous tubular heat exchanger was used. The complex coacervation ...
Novel methods to induce complex coacervation using dual fluid nozzle and metal membranes: Part I-Use of metal membranes for emulsification
(Elsevier B.V., 2022-07-01)
This study is part I of two parts where the use of metal membranes was evaluated to produce emulsions and to induce complex coacervation. In this work, we aimed to produce emulsion droplets using metal membranes to be used ...
