What is coacervation technique?
Coacervation, also called phase separation, was the technique developed in the 1950s by National Cash Register Co. Coacervation involves the separation of a liquid phase of coating material from a polymeric solution and wrapping of that phase as a uniform layer around suspended core particles.
What does coacervate mean?
Coacervate (/koʊəˈsɜːrvət/ or /koʊˈæsərveɪt/) is an aqueous phase rich in macromolecules such as synthetic polymers, proteins or nucleic acids. The dispersed droplets of dense phase are also called coacervates, micro-coacervates or coacervate droplets.
How do microcapsules work?
Microencapsulation is a technique in which chemicals are released in a controlled manner over a long period. In this process small particles or droplets are confined in a coating to give small capsules or microcapsules. The materials inside the capsules form the core and the outside coating becomes a barrier wall.
What is microencapsulation used for?
Microencapsulation is used to reduce adverse aromas, volatility, and reactivity of food products and to provide food products with greater stability when exposed to adverse conditions (e.g., light, O2, and pH) [5, 6].

Why microencapsulation is done?
 stated that microencapsulation is used in the food industry to reduce the reactivity of the active material in the external environment, reduce the speed of losses and evaporation of the core material into the medium, improve food handling, provide controlled release of the active product, mask unpleasant odor and …
How do you prepare microencapsulation?
Preparation of Microcapsules Microcapsules were prepared by dispersion in distilled water (solid content 10%, w/v) of the polymers pectin and casein under constant mechanical shaking. Sodium hydroxide (4.0 M) was used to adjust pH to 8.0 ± 0.1.
What are the application of microencapsulation?
Currently, microcapsules are utilized in beverage, bakery, meat, poultry, and dairy products. Moreover, microencapsulation has been used to increase stability, to mask bitter taste, to improve the release properties of drugs, and to provide specific drug delivery in pharmaceutical industries.
How coacervates are formed?
A coacervate is a spherical aggregation of lipid molecules making up a colloidal inclusion which is held together by hydrophobic forces. A wide variety of solutions can give rise to them; for example, coacervates form spontaneously when a protein, such as gelatin, reacts with gum arabic.
