Quaternary Salts of Chitosan: History Antimicrobial

Recently increasing attention has been paid to water-soluble derivatives of chitosan at its applications The chemical characteristics and the antimicrobial properties of these salts can play significant role in pharmacological and food areas mainly as carriers for drug delivery systems and as antimicrobial packaging materials In the current paper a historical sequence of the main

Jun 01 2018The aim of the present study was to investigate the effects of carboxymethyl cellulose (CMC) and chitosan (CH) coatings containing Mentha spicata essential oil (MSO 0 1 and 0 2%) on survival of Listeria monocytogenes and physicochemical (weight loss titratable acidity and pH) microbial (total viable count psychrotrophic bacteria as well as yeasts and molds)

Jun 07 2017The writers conducted a study about the synthesis and characterization of hydrogel chitosan-alginate by addition plasticizer lauric acid for wound dressing application The purpose was to find out the impact of lauric acid concentration variation on hydrogel chitosan-alginate to get the best mechanical and physical properties to be applied as

Mar 01 2020Several biopolymers have been studied for the development of biodegradable edible and antimicrobial films for their food packaging applications (Elsabee Abdou 2013) Such biopolymers include starch cellulose their derivatives gums proteins (animal or plant-based) and lipids ( Muxika Etxabide Uranga Guerrero de la Caba 2017 )

Development of edible film from flaxseed mucilage

For instance many studies have used polysaccharide-based edible film as a stable material that is feasible for packaging purposes (Dick et al 2016) In the present work the development of an edible film from flaxseed mucilage was investigated with the aim that it serves as an alternative to other edible films and synthetic polymer films

BACKGROUND The effect of modified atmosphere packaging (MAP ) on the stability of 'Cuello Dama Blanco' (CDB ) 'Cuello Dama Negro' (CDN ) and 'San Antonio' (SA ) figs during post‐harvest cold storage was evaluated by using three different films with a diverse number of microperforations (diameter = 100 m): M10 (16 holes) M30 (five holes) and M50 (three

Wound dressings For the preparation of non-thermal-plasma-treated alginate wound dressings sodium alginate (M:G ratio 1 6 Sigma-Aldrich St Louis MO) was suspended in de-ionized H 2 O filter sterilized poured into a mold and cross-linked with calcium to form circular hydrogels (26 mm in diameter) The hydrogels were then treated for 3 min with a non-thermal plasma

Apr 04 20121 An edible film to be adopted for use by dissolving in the mouth of a user comprising an opening-forming area in which an opening is not formed prior to use but an opening of a predetermined shape that passes through the film from one side to another side thereof can be formed at the time of use 2 The edible film according to claim 1 wherein the opening

The FT-IR spectra of the pure sodium alginate (Fig 3a) hydroxypropyl methylcellulose (Fig 3b) and esterified samples (Figs 3c 3d and 3e) were recorded The band at 3456 cm −1 is attributed to hydroxyl stretching in the HMPC and microsphere samples (Figs 3c 3d and 3e)

been obtained with edible coating based on chitosan (Duan et al 2011) aloe vera (Vieira et al 2016) and quinoa protein/chitosan/sunflower oil edible film (Abugoch et al 2016) Alginate is a hydrophilic biopolymer that has a coating function because of its unique colloidal properties which include its use for thickening

In alginate films the extract incorporation significantly decreased film solubility (6%) water vapour permeability (46%) and elasticity (24%) and had no effect on thermal properties Depending on the type of application the addition of SE in edible films can bring advantages for food conservation

Abstract This study investigated properties of starch-based edible films with oregano and black cumin essential oil addition Essential oils addition positively affected film swelling (decreased due to essential oil addition) mechanical properties (tensile strength decreased while elongation at break increased) and water vapor barrier properties (decreased along with essential oils
