Abstract :
[en] In the present study, different organic and hybrid systems for quercetin (Qr) encapsulation were developed, namely Ca-Alginate (Qr-Alg), Ca-Alginate@Na-montmorillonite (Qr-Alg@Na-Mnt), and Ca-Alginate@CPC-montmorillonite (Qr-Alg@CPC-Mnt). Attenuated total reflecting-Fourier-transform infrared (ATR-FTIR) analysis was used to characterize and prove quercetin encapsulation in the developed microcapsules. The encapsulation efficiency (EE) and loading capacity (LC) of quercetin in elaborated biomaterials were determined. Besides, the release kinetics of quercetin molecules from organic and hybrid microcapsules were carefully investigated in two different aqueous mediums; pure distilled water and distilled water containing Tween 20 (1%, w/v). The obtained results show that all developed microcapsules have a good encapsulation efficiency and loading capacity within the range 97.65 ± 0.57–99.47 ± 0.38% for the EE and 19.26 ± 0.46–23.29 ± 0.82 mg/g for the LC. The release rates of Qr from organic microcapsules Qr-Alg, hybrid microcapsules Qr-Alg@Na-Mnt, and Qr-Alg@CPC-Mnt in distilled water containing Tween 20 (1%, w/v) are 52, 49, and 113 times bigger, respectively, than release rate in distilled water. In addition, the kinetics release from hybrid microcapsules was slower in comparison to organic microcapsules. Also, in the case of hybrid microcapsules, the rate of kinetic release of quercetin from Qr-Alg@Na-Mnt was greater than the one from Qr-Alg@CPC-Mnt. This is due to the strong interactions of quercetin molecules with nanoparticle functional groups of cetylpyridinium chloride modified montmorillonite organoclay (CPC-Mnt) compared to sodium montmorillonite (Na-Mnt). The kinetics of Quercetin release from all developed organic and hybrid microcapsules follows the Korsmeyer–Peppas model and is controlled by non-Fickian diffusion.
