“…Based on the material sources, hydrogels cover two categories: synthetic polymer hydrogels and natural polymer hydrogels. [84,87,90] For synthetic polymer hydrogels, their polymerization monomers are mainly the polyethylene glycol (PEG), [20,91,92] polyvinyl alcohol (PVA), [93][94][95] polyacrylic acid (PAA), [96][97][98] polyacrylamide [99][100][101] and so on. While for natural polymer hydrogels, the commonly utilized material sources chiefly include the gelatin, [102][103][104] chitosan, [79,105,106] cellulose, [86,107] agarose, [64,108] hyaluronic acid (HA), [92,109] and other natural materials.…”

“…Several different aspects of hydrogels have been comprehensively reviewed. [79,[86][87][88][89] For instance, the applications of Chitosan hydrogels for sustained drug delivery have been reviewed by Peers et al [79] As drug delivery device, chitosan hydrogels was demonstrated to control or delay the release of drugs loaded into its 3D skeleton in the report. Gul et al reviewed the recent advances on natural polymer hydrogels, with emphasis on the food application of hydrogels.…”

“…Gul et al reviewed the recent advances on natural polymer hydrogels, with emphasis on the food application of hydrogels. [87] However, there is still a lack of general summary of the fabrication and application of hydrogels in this field, especially the systematic review of polymerization monomers, cross-linking methods and latest applications in novel hydrogels. In this review, we summarized the current material sources, cross-linking strategies and application classifications of hydrogels (Figure 1).…”

Hydrogels, as the most typical elastomer materials with three-dimensional (3D) network structures, have attracted wide attention owing to their outstanding features in fields of sensitive stimulus response, low surface friction coefficient, good flexibility, and bio-compatibility. Because of numerous fresh polymer materials (or polymerization monomers), hydrogels with various structure diversities and excellent properties are emerging, and the development of hydrogels is very vigorous over the past decade. This review focuses on state-of-the-art advances, systematically reviews the recent progress on construction of novel hydrogels utilized several kinds of typical polymerization monomers, and explores the main chemical and physical cross-linking methods to develop the diversity of hydrogels. Following the aspects mentioned above, the classification and emerging applications of hydrogels, such as pH response, ionic response, electrical response, thermal response, biomolecular response, and gas response, are extensively summarized. Finally, this review is done with the promises and challenges for the future evolution of hydrogels and their biological applications.

“…Hydrogels contain a 3-dimensional solid network structure that can swell, absorb, and retain a large quantity of water, other biological liquids, or both (Abaee et al, 2017). Hydrogels can be formulated for different purposes including protection of sensitive compounds from degradation against unfavorable environmental conditions (e.g., temperature, pH, oxidation, and light), controlled and targeted release of bioactive components, and facilitation of food structure formation and stabilization (Gul et al, 2021). Hydrogels have been widely used in the fields of pharmacy, cosmetics, agriculture, and the food industry.…”

This study investigated the effect of ultrasound and enzymatic cross-linking on the freeze-thaw (FT) stability and release properties of whey protein isolate hydrogels. We evaluated the FT stability by the changes in the microstructure, riboflavin retention, syneresis, water holding capacity (WHC), and texture of gels subjected to 3 FT cycles. High-intensity ultrasound (HUS) and transglutaminase (TGase)-mediated cross-linking improved the FT stability of whey protein isolate hydrogels loaded with riboflavin (WPISAR), as demonstrated by a more uniform and denser porous structure, significantly higher riboflavin retention, WHC, and textural properties, and lower syneresis after 3 FT cycles than those of untreated hydrogels. Furthermore, HUS-and TGase-mediated cross-linking decreased protein erosion and swelling ratio of WPISAR in simulated gastrointestinal fluids (SGIF) and reduced the riboflavin release rate in SGIF both with and without the addition of digestive enzymes. After 3 FT cycles, faster riboflavin release occurred due to a more porous structure induced by ice crystal formation compared with their unfrozen counterparts as detected by confocal laser scanning microscopy. High-intensity ultrasound-and TGase-mediated cross-linking alleviated the FT-induced faster riboflavin release rate in SGIF. High-intensity ultrasound-and TGase-treated gel samples showed that both diffusion and network erosion were responsible for riboflavin release regardless of FT. These results suggest that HUS-and TGase-mediated cross-linking improved the FT stability of WPISAR with a high riboflavin retention, and might be a good candidate as a controlled-release vehicle for riboflavin delivery to overcome undesired FT processing.

“…With the increasing global efforts to protect the ecological environment, the use of non-degradable plastic products based on petroleum-based polymers is gradually being restricted, and this has aroused considerable research interest in the utilization of natural polymers like polysaccharides. [1] As an alternative to plastic films, biodegradable polysaccharide-based film materials are receiving increased attention. Most polysaccharides are considered to be nontoxic and harmless and are widely present in nature, and can have selective permeability to carbon dioxide and oxygen.…”

An edible film containing both hydrophilic and hydrophobic components could have good mechanical and moisture barrier properties at the same time.Previous research indicated the high potential of konjac glucomannan (KGM) and ethyl cellulose (EC) film in the development of novel edible films, and this study aimed to further improve the hydrophobicity and film properties by addition of curdlan to prepare KGM/curdlan/EC ternary composite films. Results indicated that the addition could significantly change the water contact angle, moisture barrier properties, and mechanical properties of the KGM/EC films, and the optimum addition amount is considered to be 20% of the total weight of KGM and EC. The SEM images, FTIR, and XRD results indicated that the molecular interaction between curdlan and other film components is relatively weak, and this is probably cause by that curdlan remained in the triple-helix structure under the preparation condition. Therefore curdlan should mainly act as the filling components of the films, and too low or too high addition amount led to decreased mechanical and water vapor permeability properties. The obtained results may offer suggestions to prepare ternary composite edible films with curdlan addition.
