Abstract
In recent years, polysaccharide-based hydrogels have received increased attention due to their inherent biodegradability, biocompatibility, and non-toxicity. The feasibility of using polysaccharides for the synthesis of hydrogels is dependent on their noteworthy mechanical strength and cell compatibility, which are required for practical applications, especially for biomedical uses. In this study, we demonstrate a facile synthetic route for the construction of a mechanically tough, biocompatible, and biodegradable hydrogel using polysaccharides such as starch and agar. A synthetic monomer-free hydrogel was synthesized using epichlorohydrin as a cross-linker, and a mechanical strength of 9.49 ± 1.29-6.16 ± 0.37 MPa was achieved. The introduction of agar into the hydrogel resulted in agar dose-dependent swelling-induced mechanical strength. Moreover, along with incredible mechanical strength, the hydrogel also exhibited prominent cell viability against human embryonic kidney cells. In addition, the hydrogel showed good encapsulation efficiency for antibacterial drugs like ciprofloxacin hydrochloride hydrate, with controlled releasing ability over a sustained period. The antibacterial activity of the encapsulated drug was observed against Staphylococcus aureus and Bacillus subtilis bacterial strains. Thus, the studied hydrogel with loaded drug exhibited all the required qualities to be utilized as a promising candidate in wound dressing applications.

Abstract
The effect of tea polyphenols (TPs) on noodles quality was investigated, and the interaction mechanism between catechins and gliadins was explored. With TPs addition, noodles showed the significant changes in physicochemical and sensory properties. The water absorption, tensile strength and elasticity increased by 1.35%, 4.98%, 28.51% with 0.5% of TPs, and then decreased with the increasing of TPs. According to the determinations of surface hydrophobicity, spatial structure, thermal properties, amidogen and sulfhydryl content, the structure and properties of gliadin were affected by catechins. Esterified catechins tended to disrupt gliadin structures and non-esterified catechins polymerised gliadin molecules. Furthermore, molecular docking results indicated that catechins interacted with gliadin mainly by hydrogen bonds and hydrophobic action. The reactivity of catechins with gliadin was in the sequence as: epigallocatechin gallate > epicatechin gallate > epigallocatechin > epicatechin, which was based on the account of gallate and B-ring hydroxyl number discrepancy. All results suggested that catechins affected greatly on gliadin, and TPs were potentially used to improve the quality of flour products.

Abstract
The aim of this work has been to study the modification of gliadin films with cinnamaldehyde as a potential cross-linker agent. The molecular weight profile and cross-linking density showed that cinnamaldehyde increased reticulation in the resulting films. The participation of free amino groups of the protein in the newly created entanglements could be a possible mechanism of connection between the polypeptidic chains. The combination of a Schiff base and a Michael addition is a feasible approach to understanding this mechanism. The protein solubility in different media pointed to lower participation by both noncovalent and disulfide bonds in stabilizing the structure of the cross-linked films. The new covalent bonds formed by the cinnamaldehyde treatment hampered water absorption and weight loss, leading to more water-resistant matrices which had not disintegrated after 5 months. The properties of this novel bioplastic could be modified to suit the intended application by using cinnamaldehyde, a naturally occurring compound.

Abstract
Cinnamaldehyde is a naturally occurring α,β-unsaturated aldehyde. Its potential as a natural cross-linker to improve the physical performance of cast wheat gliadin films was evaluated. The cross-linking reaction was found to be dependent on the pH of the reaction medium, with pH 2 as the optimum. The water resistance (weight loss after immersion), mechanical properties (Young's modulus, tensile strength and elongation at break), thermal properties (T(g) and decomposition behavior), optical properties and morphology of films were evaluated. Cross-linked films showed high transparency, maintained their integrity after immersion, and displayed significant improvements in tensile strength and Young's modulus without impairment of their elongation properties. These effects, which were proportional to the amount of cinnamaldehyde added, highlight the possible formation of intermolecular covalent bonds between "monomeric" gliadins, leading to a polymerized network. Thus, this treatment could provide a new alternative to the toxic cross-linkers commonly employed and so extend the use of gliadin films.

Abstract
Polysaccharides are important materials in food, pharmaceutical, cosmetic and related biomedical applications. Xanthan gum is a microbial polysaccharide of great commercial significance. Lignin possesses antioxidant, antimicrobial and stabilizer properties. The aim of this study was to investigate by UV-Vis and infrared spectroscopy, wide angle X-ray scattering, differential scanning calorimetry and thermogravimetric studies, the characteristics of biodegradable superabsorbant hydrogels with high swelling rate in aqueous mediums. These were obtained by crosslinking reaction between xanthan gum and different types of lignin (aspen wood lignin, annual fibre crops lignin and lignin epoxy-modified resin) using epichlorhydrine as crosslinking agent. It is expected an increased in thermal stability, hydrophilicity, biocompatibility of hydrogel-films by lignin incorporation. Applications in the food and medical field were also found.
