“…In addition, the important factor, related to the components, is M and DD of chitosan and the substitution degree of the chitosan derivatives, in the case of their use for the biomaterials obtaining . For example, a water ‐ soluble chitosan derivatives, such as N,O‐carboxymethyl‐chitosan or O‐carboxymethyl‐chitosan can be synthesized . The substitution degree determines the number of chitosan reactive groups (amine and hydroxyl groups).…”

Today, there is a need for the development of biomaterials with novel properties for biomedical purposes. The biocompatibility of materials is a key factor in determining its possible use in biomedicine. In this study, composite cryogels were obtained based on pectin and chitosan using ionic cryotropic gelation. For cryogel preparation, apple pectin (AP), Heracleum L. pectin (HP), and chitosan samples with different physical and chemical characteristics were used. The properties of pectin-chitosan cryogels were found to depend on the structural features and physicochemical characteristics of the pectin and chitosan within them. The addition of chitosan to cryogels can increase their mechanical strength, cause change in surface morphology, increase the degradation time, and enhance adhesion to biological tissues. Cryogels based on AP were less immunogenic when compared with cryogels from HP. Cryogels based on AP and HP were hemocompatible and the percentage of red blood cells hemolysis was less than 5%. Unlike cryogels based on HP, which exhibited moderate cytotoxicity, cryogels based on AP exhibited light cytotoxicity. Based on the results of low immunogenicity, light cytotoxicity data as well as a low level of hemolysis of composite cryogels based on AP and chitosan are biocompatible and can potentially be used in biomedicine. © 2016 Wiley Periodicals, Inc.

“…The membrane produced was then characterized using an FTIR spectrophotometer. The FTIR spectra of chitosan-pectin PEC membrane cross-linked with glutaraldehyde can be seen in 1627 cm-1 which shows the existence of stretching vibrations of -COand -COOH clusters, (Hastuti & Siswanta, 2013) and (Wang, et.al, 2014).…”

Biopolymers are polymers fabricated from natural polymers which are biodegradable, non-toxic and renewable. This research was aimed to synthesize and characterize biopolymer made from chitosan and pectin and was made to be a membrane cross-linked with glutaraldehyde and then characterized. The chitosan-pectin crosslinked glutaraldehyde polyelectrolite complex (PEC) and membrane can be used as a bioadsorbent for metal and cationic dyes. Firstly, PEC membrane chitosan-pectin crosslinked glutaraldehyde was synthesized by dissolving chitosan in acetic acid and pectin in distilled water and added with glutaraldehyde as a crosslinked agent, then heated at 70 °C. The amount of 1M NaOH solution was added for 12 hours and then cleaned with distilled water and dried at room temperature. Subsequently, the membrane was characterized with FTIR spectrophotometer, medium acidity test, and water uptake. The results of the characterization of PEC mebmbrane chitosan-pectin crosslinked glutaraldehyde with FTIR showed the interaction between –NH3+ of chitosan with –COO- group of pectin at a wavelength of 1604.77 cm-1. The medium acidity test showed that the PEC membrane chitosan-pectin crosslinked with glutaraldehyde was stable at pH 3-9 with water absorption of 266.67%, with the composition of chitosan-pectine membrane of 70:30 with 30% glutaraldehyde

“…Rich in active groups, these two components could interact through ionic and/or hydrogen bonding. Furthermore, to tailor‐made the properties required for the food packaging application pectin/CMC system could be additionally cross‐linked by multivalent metal cations due to the polyanionic nature of both components . These formulations usually require the addition of plasticizers, such as glycerol or sorbitol.…”

The present paper reports on pectin based films modified with carboxymethyl cellulose intended for food packaging. The films are prepared by solvent‐casting method with different carboxymethyl cellulose content and cross‐linker concentration (Ca2+ ions) in the presence of glycerol as a plasticizer. FT‐IR spectra of the prepared films propose that carboxyl group from pectin are mainly involved in interactions with CMC, whereas −OH groups are mainly involved in self‐associated hydrogen bonding of neat polymers. Further, an addition of carboxymethyl cellulose improved mechanical properties compared to pure pectin films, while TGA analysis confirmed satisfying thermal stability regarding their potential application as packaging material. Finally, water vapor permeability values are in the range of 1.32 × 10−7 up to 2.03 × 10−7 g/m h Pa.
