Hemicellulose-based nanocomposites coating delays lignification of green asparagus by introducing AKD as a hydrophobic modifier

Carrageenan-Based Antimicrobial Films Integrated with Sulfur-Coated Iron Oxide Nanoparticles (Fe3O4@SNP)

“…The water vapor barrier property of manufactured carrageenan films was evaluated by measuring their water vapor permeabilities (WVPs) based on the ASTM E96-95 standard method. , A detailed experimental procedure is provided in our published reports. , …”

Sustainable Postharvest Treatments for Prolonging Asparagus (Asparagus officinalis L.) Shelf Life by Minimizing the Development of Physiological Disorders

“…66,69 The decreased water vapor permeability was due to the addition of montmorillonite into the hemicellulose-based films. 66,69 Montmorillonite is a natural clay mineral that has been characterized as GRAS. Due to its low cost, high aspect ratios (100−1500), high surface-tovolume ratio (700−800 m 2 •g −1 ), and good miscibility with cationic polymers, montmorillonite has the potential to be used in food science and especially in the formulation of edible coatings for extending the postharvest life of fruits and vegetables.…”

“…Edible coatings are an efficient postharvest treatment that prolongs the storage life and maintains the quality of different fresh vegetables such as carrots, potatoes, eggplants, tomatoes, and bell peppers, among others. − Edible coatings have several advantages, including operational simplicity, energy efficiency, and manufacturing scalability, and are generally recognized as safe (GRAS) since they are derived from food materials. , Edible coatings can be composed of individual materials such as polysaccharides, proteins, and lipids or combined materials (i.e., polysaccharide–lipid, polysaccharide–protein, etc. ). , Edible coatings can be applied by different methods, including spraying, dipping, and brushing .…”

“…The modified hemicellulose-based coating was the most efficient for delaying asparagus senescence and reducing the lignin content. The modified hemicellulose-based film showed increased respiratory barrier properties and decreased water vapor permeability. , Thus, the coating created a modified atmosphere, acting as an effective barrier to respiratory gases and water vapor between asparagus and the surrounding atmosphere, delaying asparagus senescence. The increased respiratory barrier properties were attributed to the alkyl ketene dimer, which increased the hydrophobicity of the coating by reacting with hydroxyl groups of hemicellulose, cellulose nanofibers, and montmorillonite. , The decreased water vapor permeability was due to the addition of montmorillonite into the hemicellulose-based films. , Montmorillonite is a natural clay mineral that has been characterized as GRAS.…”
