This study aimed to describe the properties of cold water fish gelatin (FG) blended with poultry gelatin (PG) for a production of a sachet containing olive oil. Therefore, HPH will be a promising method to promote the functional properties of gelatin for its application in the food industry. In contrast, the strain sweep and temperature sweep of gels indicated that the HPH treatment of gelatin had an undesirable effect on gel strength and decreased the elasticity and viscosity of the gel. The protein unfolding could increase emulsifying and foaming capacity and stability. ![]() As a result of this process, the microstructure of gelatin gel was altered, and the pore shape changed from a polygon, a well-oriented shape to an unordered structure. Also, the bathochromic shift of gelatin λ max at UV spectra confirmed protein unfolding after a single pass. Based on the CD spectroscopy, the structural packing of gelatin was altered after HPH treatment. ![]() The FTIR and sulfhydryl content results indicated that HPH could destroy hydrogen bonds, leading to the protein unfolding after a single HPH cycle. Regarding this goal, gelatin was prepared at concentrations of 3, 6, and 9% and homogenized at 100 MPa via single, double, and triple passes. The aim of the present study was to investigate the effects of high-pressure homogenization (HPH) on the functional, physicochemical, and structural properties of gelatin. In this study, gelatin was shown to be a potential polymer for hydrogel synthesis with highly renewable and sustainable characteristics and multiple uses. After its uses, gelatin-based hydrogels can easily biodegrade and, thus, can be sustainably used in the environment. Furthermore, they have also shown substantial performance and important characteristics for remediation for removing pollutants from water, watercourse, and effluents. For instance, these hydrogels have been used for biomedical applications such as bone reconstruction or drug delivery. ![]() Gelatin-based hydrogels have been shown to be useful for different applications with important and innovative characteristics. Furthermore, biodegradability, non-toxicity, and easy cross-linking with other substances can promote polymers with high performance and low cost for many applications, turning them into sustainable products with high acceptance in society. Thus, converting wastes such as cartilage, bones, and skins into gelatin would give them added value. Gelatin is obtained from collagen, a co-product of the meat industry. Hydrogels have become one of the potential polymers used with great performance for many issues and can be promoted as biomaterials with highly innovative characteristics and different uses. Thus, in order to synthesize more stable and resistant gelatin-based hydrogels, this biopolymer has been combined with many other polymers such as polyvinyl alcohol, alginate dialdehyde, alginate dialdehyde-gelatin reinforced with bioactive glass nanoparticles, dialdehyde carboxymethyl cellulose-dextrin, graphene oxide and laponite, collagen, chitosan, dopamine grafted, 1,4-phenylenebisboronic acid and graphene oxide, and oxidized alginate (OA) reinforced by silicon carbide nanoparticles (SiC NPs) and cross-linked with N-hydroxysuccinimide (NHS) and 1-ethyl-3-(3-dimethylaminopropyl) carbodiimide (EDC). This affects negatively the gelling ability of fish gelatin, leading to a decrease in the gelation and melting temperatures together with a worsening of its mechanical properties, among others. Depending on its origin, the content of proline and hydroxyproline might vary in fact, fish gelatin is known for having a lower concentration of these amino acids compared to that coming from mammals. ![]()
