Chitosan is a polysaccharide comprised of linked D-glucosamine and N-acetyl-D-glucosamine units. It is produced by the deacetylation of chitin, a naturally occurring polysaccharide. Chitosan is commercially used in agriculture as a biopesticide but has potential applications in the biomedical field due to its antibacterial properties. This product is derived from shrimp shell.

Cooperative crystallization effect in the formation of sonochemically grafted active materials based on polysaccharides
Yevgenia Shebis, Vijay Bhooshan Kumar, Aharon Gedanken, Elena Poverenov
Colloids and Surfaces B: Biointerfaces, 110931, 190 (2020)

The current study explores the formation of active eco-friendly materials capable of preventing microbial contamination using in situ ultrasonic grafting of vanillin, curcumin and a curcumin-vanillin mixture on the surfaces of carboxymethylcellulose (CMC) and chitosan films. Spectroscopic, microsco… read more

Preparation and characterization of poly(ethylene terephthalate) films coated by chitosan and vermiculite nanoclay
Fatima Essabti, Alain Guinault, Sébastien Roland, Gilles Régnier, Saïd Ettaqi, Matthieu Gervais
Carbohydrate Polymers, 392-401, 201 (2018)

Chitosan (CS) layers are coated on a poly(ethylene terephthalate) (PET) film in order to decrease the oxygen permeability through the polymeric films for food packaging applications. Oxygen transmission rate (OTR) of the 130 μm PET films can be decreased from 11 to only 0.31 cm3/m².day with a coate… read more

Elicitation of fruit defense response by active edible coatings embedded with phenylalanine to improve quality and storability of avocado fruit
Lilah Saidi, Danielle Duanis-Assaf, Ortal Galsarker, Dalia Maurer, Noam Alkan, Elena Poverenov
Postharvest Biology and Technology, 111442, 174 (2021)

Edible coatings attract high research attention as an effective natural approach for maintaining fresh agricultural produce quality and storability. In this study, a series of polysaccharide-based coatings that contain, for the first time, an elicitor of fruit defense response, phenylalanine, were … read more

Non-radical synthesis of chitosan-quercetin polysaccharide: Properties, bioactivity and applications
Yevgenia Shebis, Alexander Laskavy, Anat Molad-Filossof, Hadar Arnon-Rips, Michal Natan-Warhaftig, Gila Jacobi, Elazar Fallik, Ehud Banin, Elena Poverenov,
Carbohydrate Polymers, 119206, 284 (2022)

Quercetin-chitosan (QCS) polysaccharide was synthesized via non-radical reaction using L-valine-quercetin as the precursor. QCS was systematically characterized and demonstrated amphiphilic properties with self-assembling ability. In-vitro activity studies confirmed that quercetin grafting does not… read more

Chitosan-collagen hydrogel microparticles as edible cell microcarriers for cultured meat
Anton Zernov, Limor Baruch, Marcelle Machluf
Food Hydrocolloids, 107632, 129 (2022)

Offering conventional meat-like nutritional values and eating experience without harming animals or the environment, cultured meat from livestock animal cells is considered one of the leading solutions to the global food crisis. Cell microcarriers (MCs) have been widely used for the scalable expans… read more
