Physical, Structural, Barrier, and Antifungal Characterization of Chitosan–Zein Edible Films with Added Essential Oils
Edible films (EFs) have gained great interest due to their ability to keep foods safe, maintaining their physical and organoleptic properties for a longer time. The aim of this work was to develop EFs based on a chitosan-zein mixture with three different essential oils (EOs) added: anise, orange, and cinnamon, and to characterize them to establish the relationship between their structural and p...
متن کاملPreparation and characterization of starch/carrageenan edible films
The mechanical and water vapor permeability of starch/carrageenan cast films were investigated, the rheological properties of starch/carrageenan blends were also studied. The blends were prepared by different concentrations of starch and carrageenan. Three concentration of starch (0.75%, 1% and 1.25%) and two concentrations of carrageenan (0.5% and 0.75%) were used with adding 0.5% glycerol as ...
متن کاملCharacterization of Corn Starch Films Reinforced with CaCO3 Nanoparticles
The characterization of corn starch (CS) films impregnated with CaCO3 nanoparticles was investigated. Criteria such as morphology, crystallinity, water vapor permeability (WVP), opacity, and mechanical properties were the focus of the investigation. It was found that the CaCO3 contents had significant effects on the tensile properties of the nanocomposite films. The addition of CaCO3 nanopartic...
متن کاملFactors affecting the physical properties of edible composite film prepared from zein and wheat gluten.
The effects of zein ratio, concentration of glycerol, liquid-solid ratio, ethanol concentration, pH and heat-treatment temperature on the properties of zein/wheat gluten composite films were researched. The results showed that elongation (E) increased with an increase in glycerol or ethanol concentrations, but it first increased and then decreased with increasing zein/wheat gluten ratio, heat-t...
متن کاملProperties of Films from Corn Zein Reacted with Glutaraldehyde
To improve the mechanical properties of zein films, a commercial white zein was reacted in glacial acetic acid (HAc) with glutaraldehyde (GDA) from 0.5 to 16% by weight based on the weight of zein. Amounts of 4% or higher GDA-modified zein, when cured in a closed system, generated a gel. That gel was insoluble in organic solvents known to solubilize zein. Zein solutions cast within a silicon ru...
