Formation of composite hydrogel of carboxymethyl konjac glucomannan/gelatin for sustained release of EGCG

Effect of honeysuckle leaf extract on the physicochemical properties of carboxymethyl konjac glucomannan/konjac glucomannan/gelatin composite edible film

“…The addition of CMKGM affects the surface of the film slightly unevenly. This possibly due to the electrostatic interaction between the carboxymethyl group in the CMKGM molecule and the amino group in the gelatin to form a network structure ( Wang et al, 2022 ), and resulted in a compact morphology of the CMK film. With the addition of HLE, cracks and visible voids were observed in the films, and there were slight agglomerations, which confirmed that HLE affected the microstructure of the biopolymer network.…”

“…Carboxymethyl konjac glucomannan (CMKGM) is one of the most important derivatives of KGM, and CMKGM is a typical anionic polysaccharide with amphiphilic properties due to carboxymethylation and deacetylation could endow its hydrophobicity ( Xiao et al, 2015 ). CMKGM is often used in the preparation of nanogels ( Wang, Zhou, Zheng, & Pang, 2022 ), but there are few studies on the preparation of active packaging films by CMKGM.…”

Generation of multicellular tumor spheroids via 3D cell culture utilizing a hydrogel comprising chitosan and allylthiourea

“…CSATU hydrogels are shown to exhibit strong intramolecular H-bonding, likely due to the abundance of hydrophilic hydroxyl groups, as previously evidenced by TGA analysis. 57 The endothermic transitions are seen to increase in the order of CSATU-1 o CSATU-2 o CSATU-3, suggesting an increase in the compactness and rigidity of the hydrogels. The absence of any observed T g within the range of body temperature, as confirmed by the DSC analysis, indicates that these hydrogels can be useful for biomedical applications.…”

Highly Hydrophobic Gelatin Nanocomposite Film Assisted by Nano-ZnO/(3-Aminopropyl) Triethoxysilane/Stearic Acid Coating for Liquid Food Packaging

“…The fabrication of THA was according to our previous report with minor modifications. 35 Briefly, 6 g of n-HA was dispersed in 200 mL of distilled water, and 1 mol/L Tris buffer solution was added constantly until the pH = 8.0. Then, 3 g of TA was added, and the mixture was magnetically stirred (600 rpm) for 24 h at 25 °C.…”

“…In our previous report, 34 we found that the attachment of musselinspired poly(dopamine) (PDA) coatings on the surface of carbon nanotube (CCNT) could significantly enhance the water dispersibility of CCNT. Here, we used TA, a derivative of PDA, 35 for the modification of n-HA by forming functional coatings on the surface of n-HA through oxidative selfpolymerization of TA in a weak alkaline environment (Figure 1b). The change of functional groups of THA was revealed by FT-IR (Figure S4a).…”
