Abstract The main goal of the article is the creation and study of thermosensitive and wound-healing gelatin-alginate biopolymer hydrogels modified with humic acids. Their rheological properties, swelling and contraction behavior were experimentally investigated, elucidated using Fourier transform infrared spectroscopy and used to achieve the physiological melting point, which is necessary for successful drug delivery. It has been shown that in the gelatin-alginate-humic acid biopolymer hydrogels systems, it is possible to obtain a gel-sol transition temperature close to the physiological temperature of 37°C, which is important for drug delivery in the treatment of wounds. By changing the… More > Graphic Abstract

Abstract Maillard reaction is a non-enzymatic browning reaction and its products (MRPs) have been proven to possess antioxidant properties. This research aimed to produce a fish gelatin-based packaging incorporated with MRPs to retard lipid oxidation in chicken skin oil (CSO) during storage at ambient temperature (28°C–30°C). MRPs produced from fish gelatin and fructose (1:1, 90°C, pH 11) showed the highest antioxidant properties compared to those prepared under other conditions. Different glycerol/MRPs ratios (30:0, 25:5, 20:10, 15:15, 10:20, 5:25, 0:30) were incorporated into the film and resulting films were characterized. Glycerol/MRPs at 10:20 ratio was chosen to… More > Graphic Abstract

Abstract In current research work, we have studied the blending effect of non-mulberry silk fibroin (10% weight/volume basis) and gelatin (20% weight/volume basis) in formic acid. Several blends as SF10G0, SF2G8, SF3G7, SF5G5 and SF0G10 have been made and their rheological behaviour was investigated. The blend solutions were subjected to a steady shear rheological study in the variety of range of shear rates, namely 0.01–500 sec-1 and the viscosities of blend solutions were noticed to decrease in comparison to pure silk solution. The frequency sweep was employed in dynamic rheological tests to determine complex viscosity of More >

Abstract The issue of plastic pollution has attracted widespread social attention. Gelatin is valued as a degradable bio-based material, especially as an edible active packaging material. However, the commonly used solution-casting filmforming technology limits the mass production of gelatin films. In order to improve the production efficiency and enhance the commercial value of gelatin films, in this study, fish gelatin (FG) particles were successfully blended with essential oils (EOs) to prepare active films by melt extrusion technique, a common method for commercial plastics, and applied to bread preservation. FG and EOs showed good compatibility with each… More > Graphic Abstract

Abstract Silver nanoparticles (Ag NPs) are an effective antibacterial agent, but their application in food packaging is limited due to their easy agglomeration and oxidation. In this study, antibacterial microcapsules were fabricated using Ginkgo biloba essential oil (GBEO) as core material and chitosan and type B gelatin biopolymer as capsule materials. These antibacterial microcapsules were then modified with green-synthesized Ag NPs, blended into the biopolymer polylactic acid (PLA), and finally formed as films. Physicochemical properties and antibacterial activity against Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) were evaluated. Results showed that the prepared antibacterial PLA films exhibited excellent antibacterial More > Graphic Abstract

Abstract As a non-toxic, highly reactive biomass material, gelatin is wildly used as the component of biomass-based adhesive. However, like most aqueous adhesives, gelatin-based adhesives suffer from long solidifying time or high solidifying temperature due to the low volatility of water, which highly limits the application potential of gelatinbased adhesives. Inspired by the fast adhesion of marine organisms through the formation of chemical crosslinks, herein, a kind of low temperature curable eco-friendly gelatin-based adhesive with good adhesive properties and fast curing at low temperature is developed by introducing clicking chemical Diels-Alder (DA) reaction between blocked waterborne More > Graphic Abstract

Abstract In recent years, the improvement of biomedical materials and their applications have gained much interest and been broadly discussed. Hydrogel, gelatin methacrylate (GelMa), is one of the applications with the greatest potential, such as cell culture, and studied by many researchers. In this study, a system consisting of GelMa and the special particles which can be aligned by applying electric field is developed. The alignment of the particles can alter the curvature of the GelMa substrate. The proposed system which provides the mechanical stimulus to the cell attached on the system due to different deformation… More >

Abstract Blends of gelatin (Ge) plasticized with varying amounts of glycerol (Gly), buffer solution pH 10 and epoxidized soybean oil (ESO) to enhance hydrophobicity were prepared by mixing and injection-molding. Blends were characterized by rheological tests and microscopy to select optimal conditions for scaling up their processing. The effect of each component on rheological response was analyzed using parallel plate geometry. Coating of gelatin specimens with PDMS during rheological tests led to reliable and reproducible results since water evaporation was prevented. A gradual increment in ESO concentration led to blends with increased degree of phase separation, More >

Abstract Organic rodlike cellulose nanocrystals extracted from sisal fibers and inorganic montmorillonite based on silicate layers were employed to develop bionanocomposites based on gelatin matrix. Bionanocomposites with cellulose nanocrystal, montmorillonite and both nanoreinforcements combined were characterized by Fourier transform infrared spectroscopy, thermogravimetric analysis and differential scanning calorimetry. Tensile properties and oxygen and water vapor gas permeability values were determined to study the influence of the addition of nanoreinforcements, different in nature, to gelatin matrix. Bionanocomposites with montmorillonite improved tensile strength but systems reinforced with nanocellulose showed lower tensile strength than neat gelatin ones. Oxygen gas permeability More >

Abstract A study of the potential for gelatin-based derivatives to serve as biorenewable, biodegradable adhesives for wood and engineered wood products is presented in this article. The effect of gelatin-to-water weight percent on the mechanical, specifically ultimate breaking (bond) strength, and thermal properties was investigated using tensile testing and differential scanning calorimetry, respectively. The breaking strengths of the gelatin-based adhesives were characterized and compared to four commercially available wood adhesives. The effect of 1–5% tannin addition on the mechanical, thermal, and moisture absorption behavior of the gelatin-based adhesives was also investigated. Results show that the gelatin-based More >
