AB  - The paper reports about the preparation and characterization of hydrogel particles containing liposomes loaded with resveratrol as an active compound. The materials used for preparation of the particles were chosen to be suitable for food industry. Different polymer concentrations affect particles shape, size, size distribution, as well as the release kinetics of resveratrol. The diameter of particles varied from 360 to 754 μm, while the narrow size distribution was observed for all types of particles. Release studies were performed in Franz diffusion cell and the results showed the prolonged release of resveratrol from all samples, but the sample with the highest content of polymer (2.5% w/w) in particular stood out. The research provides useful information about liposomes containing active compound encapsulated in hydrogel matrices and offers the basis for its application in the food industry.
AB  - Ovaj rad daje podatke o pripremi i karakterizaciji čestica koje sadrže lipozome sa inkapsuliranom aktivnom komponentom resveratrolom. Komponente koje ulaze u sastav ovih čestica odabrane su tako da mogu jednostavno da se primene u prehrambenoj industriji. Prikazan je uticaj različitih koncentracija početnih rastvora polimera čija upotreba je dozvoljena u hrani, a samim tim i njihove viskoznosti na veličinu formiranih čestica, njihov oblik i raspodelu veličina, ali i na otpuštanje resveratrola iz ovih složenih sistema. Prečnik čestica bio je između 360 i 754 μm, dok je uska raspodela veličina detektovana u svim uzorcima. Otpuštanje resveratrola praćeno je u Francovoj difuzionoj ćeliji gde su rezultati ukazali na produženo oslobađanje resveratrola u svim uzorcima. Ipak, uzorak koji je imao najveći udeo polimera u početnom rastvoru (2,5% w/w) najsporije je otpuštao aktivnu komponentu. Ovi rezultati daju korisne podatke o kompleksnim sistemima gde je aktivna komponenta inkapsulirana u lipozome dalje obložena polimerom čime doprinose potencijalnoj aplikaciji ovih i sličnih sistema u prehrambene proizvode.

AB  - We reported the design of liposome-loaded Ca-alginate microspheres as a drug delivery system for controlled release of resveratrol. The effect of admixed sucrose and chitosan coating was assessed in terms of physicochemical, thermal and release properties of liposome-in alginate systems with encapsulated resveratrol. The diameter of liposomes produced by proliposome method increased from 412 to 471 nm with addition of sucrose as a cryoprotectant. DSC analysis revealed that phospolipids interact with each other while forming the lipid bilayer and that resveratrol was incorporated within the lipid bilayer, causing destabilizing effect in the two temperature regions (137–202 °C and 240–270 °C). Liposomes were entrapped within polymer network and remained intact as determined by SEM cross-sectional observation of the microbeads. Liposomes interfered with the thermal behavior of alginate in the temperature region above 220 °C. The presence of liposomes decreased the strength of the beads in comparison to placebo beads, according to mechanical tests on compression. Release studies performed in Franz diffusion cell showed the overall resistance to mass transfer one order of magnitude higher (106 s/m) than the resistance ascribed solely to the liposomal membrane. The chitosan coating, visible as a dense surface layer (∼7 μm thick) in dry state, caused decrease in encapsulation efficiency of resveratrol (85% vs. 91%) and in size of the particles (d50 of 387 vs. 440 μm); the chitosan also caused weakening of the polymer matrix, but increased resistance to drug diffusion (11.4 × 105 s/m) in comparison to the uncoated alginate-liposome formulation (9.1 × 105 s/m).
