“…Among biopolymers, chitosan have antibacterial and antifungal activity per se, which is attributed to changes in cellular permeability of microorganisms caused by electrostatic interactions between the chitosan amine groups and the electronegative charges on cellular surface (Lunkov et al, 2018). The introduction of an active monomer into the polymer chain could be an alternative route that conduct to polymers with new functionalities (Dainelli et al, 2008).…”

Food packaging has a crucial function in the modern food industry. New food packaging technologies seek to meet consumers and industrial's demands. Changes related to food production, sale practices and consumers' lifestyles, along with environmental awareness and the advance in new areas of knowledge (such as nanotechnology or biotechnology), act as driving forces to develop smart packages that can extend food shelf-life, keeping and supervising their innocuousness and quality and also taking care of the environment. This review describes the main concepts and types of active and intelligent food packaging, focusing on recent progress and new trends using biodegradable and biobased polymers. Numerous studies show the great possibilities of these materials. Future research needs to focus on some important aspects such as possibilities to scale-up, costs, regulatory aspects, and consumers' acceptance, to make these systems commercially viable.

“…Forinstance,they are believed to be the major origin of antibacterial activity,where positively charged NH 3 + groups have an affinity for negatively charged cell membranes and disrupt their substance transport. [193,194] Adsorption/chelation for capturing metal ions [195] and CO 2 [196] is another attractive function of NH 2 .…”

Chemistry of Chitosan Aerogels: Three‐Dimensional Pore Control for Tailored Applications

et al. 2020

View full text Add to dashboard Cite

Chitosan is an abundant biopolymer derived from food waste with attractive properties, particularly its high biocompatibility and easy chemical processability. Here, we review the rapidly expanding literature on chitosan‐based porous materials with a focus on the gelation mechanisms, the three‐dimensional multiscale structural control, and the diverse chemical functionality not accessible by other biopolymers. The properties vary widely: from supercritically dried, mesoporous chitosan aerogels to very light, freeze‐dried macroporous scaffolds. Porous chitosan displays impressive performance at the laboratory scale, but the highly (meso)porous nature amplifies not only the beneficial functionality of chitosan, but also its drawbacks, resulting in serious barriers to industrialization. In order to facilitate technology transfer, we critically discuss the practical feasibility of chitosan aerogels in potential applications compared to conventional and other biopolymer‐based porous or nonporous materials.

Indiesem Aufsatz diskutieren wir die schnell wachsende Zahl an Literaturbeiträgen zu Chitosan-basierten porçsen Materialien, mit Schwerpunkt auf Gelierungsmechanismen, dreidimensionaler multiskaliger Strukturkontrolle sowie der mannigfaltigen chemischen Funktionalität, die mit anderen Biopolymeren nicht erreichbar ist. Die Eigenschaften unterscheiden sich von letzteren teils stark:v on überkritischg etrockneten, mesoporçsen Chitosan-Aerogelen bis hin zu äußerst leichten, gefriergetrockneten makroporçsen Gerüsten. Im Labormaßstab erreicht porçses Chitosan beeindruckende Eigenschaften, der hoch(meso)porçse Charakter verstärkt jedoch nicht nur die vorteilhafte Funktionalitätdes Chitosans,sondern auchseine Nachteile,was eine mçgliche Industrialisierung ernsthaft einschränkt. Zur Fçrderung des Technologietransfers diskutieren wir in kritischer Weise die praktische Umsetzbarkeit mçglicher Anwendungen von Chitosan-Aerogelen im Vergleich zu konventionellen und anderen biopolymerbasierten porçsen oder nichtporçsen Materialien.
