“…The effect of chitosan concentration Cationic polysaccharides-chitosan and anionic polysaccharides-gellan gum can form a polyelectrolyte complex membrane through electrostatic interaction [28], which is supposed to increase the strength of the calcium-gellan gum beads and decrease their permeability. The results indicated that chitosan played a crucial role in the modulation of the release and swelling of beads during the GI transit (Fig.…”

The bead system composed of chitosan and calcium-gellan gum was prepared through a combination of ionotropic gelation and polyelectrolyte complexation for oral protein delivery. The characteristics of beads were investigated by scanning electron microscopy, Fourier transform infrared spectroscopy, differential scanning calorimetry, X-ray diffraction, release studies, and swelling measurements. It was found that chitosan endowed the calcium-gellan gum beads a dense surface and the crystal structure of polymers was disrupted after being combined together. The encapsulation efficiency of protein was in the range of 65-85 %. Higher gellan gum concentration combined with vacuum dryness significantly retarded protein fast release at pH 1.2 and achieved sustained release at pH 6.8, whereas providing efficient release at pH 7.4. The protein release was mainly attributed to Fickian diffusion mechanism in the process of swelling. The chitosan-calcium-gellan gum beads have the potential to act as a new carrier for controlled release of protein-based functional ingredients.

“…Amin et al [33] produced films from chitosan (cationic) and GG (anionic) through polyelectrolyte complexation. This study showed that physicochemical properties of the films prepared by immersing chitosan films into GG solutions can be easily finetuned by adjusting the chitosan:GG ratio.…”

“…To date, a limited number of CH-GG polyelectrolyte complexes have been reported which focus on the development of capsules and fibers [16][17][18][19][20]. Our recent work has shown that free-standing films can be formed using polyelectrolyte complexaton of CH and GG [21] and that these dual-layer films can be engineered to exhibit antibacterial activity while supporting growth of cells [22].…”

The formation of polyelectrolyte complex (PEC) wool fibers formed by dipping chitosan or gellan gum-treated wool fibers into biopolymer solutions of opposite charge is reported. Treating wool fibers with chitosan (CH) and gellan gum (GG) solutions containing food dyes resulted in improved mechanical characteristics compared to wool fibers. In contrast, pH modification of the solutions resulted in the opposite effect. The mechanical characteristics of PEC-treated fibers were affected by the order of addition, i.e., dipping GG-treated fibers into chitosan resulted in mechanical reinforcement, whereas the reverse-order process did not
