Abstract: Technique of complex coacervation was used to produce microcapsules of Lactobacillus acidophilus La-5 encapsulated in gelatin and gum arabic which were then freeze-drying. Microcapsules were characterized using scanning electron and optical microscopy, and resistance of probiotics was evaluated during release into a simulated gastrointestinal tract and storage at different temperatures. The complex coacervation process produced microcapsules with a high encapsulation efficiency (77.60% and 87.53%), ranging fro… Show more

“…Successful methods used in the microencapsulation of probiotics include: spray drying [21,22]; spray chilling (also called spray cooling or congealing) [23,24]; spray freeze drying [25,26]; lyophilisation [27,28]; electrospraying [29,30]; layer-by-layer [31,32]; fluidised bed drying [33,34]; extrusion [35,36] and its improved version: the vibrating nozzle technology [37,38]. Emulsification [39,40] and coacervation [41,42] are other important and often used physicochemical techniques. Although uniform particle size distribution may be preferred in many applications, these different microencapsulation methods produce microcapsules with a wide range of particle sizes.…”

“…The fact that gelatine is one of the oldest and multiple-purposes ingredients in the food industry makes it also one of the most studied proteins as coating agent in the preparation of microcapsules [152]. Moreover, the properties of gelatine and its ability to interact with a wide variety of polysaccharides allows its use as a coating material in a several microencapsulation methods, such as extrusion, complex coacervation, spray chilling, spray drying, and lyophilisation [23,42,67,100,153,154]. Another particular advantage of using gelatine as a coating material is its linear structure, which provides a better oxygen barrier than globular proteins.…”
