Sažetak
Encapsulation is a technology that involves packing active agents (liquids, gases or solids) into capsules of different sizes and properties. The wall material used and the encapsulation method itself depend on the active component to be encapsulated. Among numerous coating materials that are used, the most commonly are polysaccharides (alginate, chitosan), lipids (phospholipids), proteins (soy proteins) and plant exudates (gum Arabica). These materials have to be food- grade, biodegradable and able to form a protective barrier between the active compounds and their surroundings. There are two different encapsulation techniques, mechanical (spray drying, spray cooling, freeze-drying, extrusion) and chemical (emulsification, coacervation, molecular inclusion, ionic gelation, application liposomes and yeasts). Encapsulation has been widely employed in food, cosmetics, chemical, and pharmaceutical industries owing to its broad benefits. This way of packaging active substances enables masking of unpleasant odours and tastes, protection from external influences such as light and moisture during storage, mixing of substances that do not mix otherwise, enhancing of physicochemical properties or visual form of active components as well as safe handling of the toxic materials. Furthermore, bioactive compounds, such as drugs and polyphenols, have been encapsulated to allow their targeted release and greater bioavailability.
