“…According to the above mechanism, Chen et al [ 67 ] found that, due to the poor wettability of ovalbumin and protein aggregation at the isoelectric point θ lower (about 61.7°), by adding tannic acid, due to hydrogen bonding, the θ increased to around 90° and stable high internal phase Pickering emulsion was formed. Li et al [ 68 ] similarly found that, with chitosan adsorption on a barley protein surface via hydrogen bonding and hydrophobic interaction, θ changed from 116.5° to 89.3°, which improved particle hydrophilicity.…”

High internal phase Pickering emulsion (HIPPE) is a type of emulsion stabilized by solid particles irreversibly adsorbed on an interfacial film, and the volume fraction of the dispersed phase (Φ) is larger than the maximum packing volume fraction (Φmax). Proteins, polysaccharides, and their composite particles can be used as good particle stabilizers. The contact angle can most intuitively demonstrate the hydrophilicity and hydrophobicity of the particles and also determines the type of emulsions (O/W or W/O type). Particles’ three-phase contact angles can be adjusted to about 90° by compounding or modification, which is more conducive to emulsion stability. As a shear thinning pseudoplastic fluid, HIPPE can be extruded smoothly through 3D printer nozzles, and its high storage modulus can support the structure of printed products. There is huge potential for future applications in 3D printing of food. This work reviewed the biomacromolecules that can be used to stabilize food-grade HIPPE, the stabilization mechanism of the emulsions, and the research progress of food 3D printing to provide a reference for the development of advanced food products based on HIPPE.

“…Carboxymethyl modification of chitosan improves the solubility and reactivity of chitosan without affecting the biocompatibility, thus making the carboxymethyl chitosan (CMC) an excellent candidate for preparation of hydrogels [14]. Meanwhile, tannic acid (TA) is a natural high phenolic hydroxyl molecule, and has excellent ROS scavenging ability and biocompatibility as well as possibility for functionalization [15]. Recent studies have shown that tannins as bioactive components have neuroprotective effects on neurodegenerative diseases through multiple actions including anti-inflammatory activities, antioxidant capacity, modulation of cell signaling pathways, and anti-amyloid actions [16,17].…”

Background Parkinson’s disease (PD) is one of the most common long-term neurodegenerative diseases. Current treatments for PD are mostly based on surgery and medication because of the limitation and challenges in selecting proper biomaterials. In this study, an injectable bioactive hydrogel based on novel tannic acid crosslinker was developed to treat PD. Methods The oxidized tannic acid modified gold nano-crosslinker was synthesized and used to effectively crosslink chitosan for preparation of the bioactive self-healing hydrogel. The crosslinking density, conductivity, self-healing ability, and injectability of the hydrogel were characterized. Abilities of the hydrogel to promote the proliferation and differentiation of neural stem cells (NSCs) were assessed in vitro. Anti-inflammatory property was analyzed on J774A.1 macrophages. The hydrogel was injected in the PD rat model for evaluation of the motor function recovery, electrophysiological performance improvement, and histological repair. Results The hydrogel exhibited self-healing property and 34G (~ 80 μm) needle injectability. NSCs grown in the hydrogel displayed long-term proliferation and differentiation toward neurons in vitro. Besides, the hydrogel owned strong anti-inflammatory and antioxidative capabilities to rescue inflamed NSCs (~ 90%). Brain injection of the bioactive hydrogel recovered the motor function of PD rats. Electrophysiological measurements showed evident alleviation of irregular discharge of nerve cells in the subthalamic nucleus of PD rats administered with the hydrogel. Histological examination confirmed that the hydrogel alone significantly increased the density of tyrosine hydroxylase positive neurons and fibers as well as reduced inflammation, with a high efficacy similar to drug-loaded hydrogel. Conclusion The new bioactive hydrogel serves as an effective brain injectable implant to treat PD and a promising biomaterial for developing novel strategies to treat brain diseases.
