Antimicrobial Films Based on Na-alginate and κ-carrageenan

Functional chitosan-based grapefruit seed extract composite films for applications in food packaging technology

“…Pure chitosan film had a TS of 54.9 MPa, while the TS of chitosan-based composite films with 0.5, 1.0 and 1.5% v/v GFSE decreased to 20.6, 8.84 and 8.39 MPa, respectively. The decrease in TS corresponded to the results reported by Cha et al [7] in which TS of Na-alginate and kappa-carrageenan base film also decreased with the inclusion of GFSE. The lower TS of chitosan-based composite films could be attributed to the reduction of intermolecular interactions between chitosan chains in the presence of GFSE within the film matrix.…”

“…The lower TS of chitosan-based composite films could be attributed to the reduction of intermolecular interactions between chitosan chains in the presence of GFSE within the film matrix. Despite the reduction in TS of chitosan-based composite films, it was noted that chitosan-0.5% v/v GFSE composite film exhibited a TS of 20.6 MPa that was comparable to the TS of polyethylene (13-28 MPa), a commonly used synthetic film [7,17].…”

“…Consumers are also demanding the packaging materials to be formulated from natural materials, environmentally friendly and biodegradable while improving food preservation [2][3][4][5][6][7]. Chitosan, a natural biopolymer has immense potential for applications in food technology, owing to its biocompatibility, non-toxicity, short time biodegradability and excellent film forming ability.…”

Preparation of a visual pH-sensing film based on tara gum incorporating cellulose and extracts from grape skins

“…between TG molecules and CNC [26]. The same behavior was found in a Na-alginate/kappa-carrageenan matrix with the addition of grape fruit seed extract [27]. However, the EAB value of TG/CNC-based composite films increased significantly.…”

Effect of Polysaccharide Species on Storage Stability of Alginate Capsules Containing <i>α</i>-Tocopherol

“…Among polysaccharides, sodium alginate is a typical capsule shell material and extremely many works about the alginate microcapsules have been reported [11] [12] [14].…”
