“…The weight gain of the whole vials attached with the films was periodically measured every 2 h during the 24 h. Plot the curve of changes in the weight versus time and the water vapor transmission rate was obtained by the slope of the linear region divided by the film area. The WVP was calculated by the way of the water vapor transmission rate multiplied by the thickness of the film and divided by the pressure difference between the inner and outer surfaces, expressed as equation (3). The WVP values of the films were determined in triplicate.…”

“…2 Many attempts have been made progress to find green packaging materials from natural resources and the carbohydrate based polymers were considered as environmentally feedstock to substitute the fossil materials. 3,4 Starch is one of the most competitive candidates for this respect because of its advantage of being an inexpensive renewable source, available worldwide, plentiful and relatively easy to manage. 5,6 The processing conditions and properties of starch film strongly depend on the ratio of amylose and amylopectin and increasing the amylose ratio could generally enhance the above-mentioned properties.…”

The preparation of biodegradable composite films from blending chitosan in maize starch via solution casting was explored and the effect of the ratio of chitosan/starch on the physicochemical, mechanical properties and antimicrobial activity of the films was investigated. The interaction through hydrogen bonding between starch molecules and chitosan and the reduction of crystallinity in blend films were revealed in FTIR and XRD results. The blend films with incorporation of proper amounts of chitosan to a maize starch matrix displayed an enhancement in tensile properties and water vapor barrier performance, an improvement in rigidity and antimicrobial activity accompanied by higher transparency. The film with 1/3 of chitosan/starch ratio appeared homogeneous structure, 21.54 ± 0.78 MPa of tensile strength and (2.81 ± 0.26)×10−10 g·m−1·s−1·Pa−1 of water vapor permeability which were 1.52 times higher and 60.9% lower than those of starch film, respectively. The deteriorated comprehensive performance of the films could be caused by excessively high chitosan content because of an incomplete miscibility between starch and chitosan. The chitosan/starch blend film possessed reasonable thermal stability and it could potentially be useful for food packaging applications.

“…Edible packaging films have recently become a research hotspot because they are environmentally friendly and can be used in food packaging. Currently, the raw materials for preparing edible packaging films mainly include polysaccharides, proteins, and lipids [ 1 , 2 , 3 , 4 ]. Owing to the different raw materials used in packaging, the performance of different packaging films differs.…”

Soybean protein isolate (SPI) and its four fractionated products (7S globulin, 11S globulin, upper soybean residue, and lower soybean residue) were compared by fabricating films and film liquids. The separation and grading effects, rheological properties of the film liquids, and difficulty in uncovering the films, in addition to the mechanical properties, water vapor permeability, oil permeability, and surface morphology of the films, were investigated. Results showed that the centrifugal precipitation method could be used to produce fractionated products. The 7S and 11S globulin films exhibited better hydrogels at lower shear rates than the other SPIs; however, they were more difficult to uncover. The tensile strength of the graded films decreased by varying degrees. However, the elongation at the break of the upper soybean residue film considerably increased, reaching 70.47%. Moreover, the permeability and surface morphology of the film were enhanced or weakened. The fractionated products, 7S and 11S globulin films, exhibited better performance. Overall, this study provides a basis for the improved development and use of fractioned SPI products.
