“…Fully bioderived Pickering systems have also been formed by the addition of an emulsion stabilized by nanochitin. [ 103 ] Nanocellulose‐ and nanochitin‐stabilized corn O/W emulsions were prepared separately with average droplet diameters of 14.3 and 1.68 μm and ζ ‐potentials of −41 (pH 6.6) and +47 mV (pH 2.9), respectively. The combination of emulsions enabled the tuning of the droplet diameter and emulsion viscosity, while synergistically improving storage stability.…”

Bio‐based Pickering emulsifiers are a nontoxic alternative to surfactants in emulsion formulations and heterogenous polymerizations. Recent demand for biocompatible and sustainable formulations has accelerated academic interest in polysaccharide‐based nanoparticles as Pickering emulsifiers. Despite the environmental advantages, the inherent hydrophilicity of polysaccharides and their nanoparticles limits efficiency and application range. Modification of the polysaccharide surface is often required in the development of ultrastable, functional, and water‐in‐oil (W/O) systems. Complex surface modification calls into question the sustainability of polysaccharide‐based nanoparticles and is identified as a significant barrier to commercialization. This review summarizes the use of nanocelluloses, ‐starches, and ‐chitins as Pickering emulsifiers, highlights trends and best practices in surface modification, and provides recommendations to expedite commercialization.

“…Zhou et al prepared mixed Pickering emulsions by blending anionic nanocellulose-stabilized lipid droplets with cationic nanochitin-stabilized lipid droplets, whose rheological properties were characterized by dynamic shear rheometry [92] (Figure 20). Zhou et al prepared mixed Pickering emulsions by blending anionic nanocellulose-stabilized lipid droplets with cationic nanochitin-stabilized lipid droplets, whose rheological properties were characterized by dynamic shear rheometry [92] (Figure 20). They successfully proved that pickering emulsions with different rheological characteristics could be prepared by blending positive and negative droplets together in different ratios.…”

Industrial sea food residues, mainly crab and shrimp shells, are considered to be the most promising and abundant source of chitin. In-depth understanding of the biological properties of chitin and scientific advancements in the field of nanotechnology have enabled the development of high-performance chitin nanomaterials. Nanoscale chitin is of great economic value as an efficient functional and reinforcement material for a wide range of applications ranging from water purification to tissue engineering. The use of polymers and nanochitin to produce (bio) nanocomposites offers a good opportunity to prepare bioplastic materials with enhanced functional and structural properties. Most processes for nanochitin isolation rely on the use of chemical, physical or mechanical methods. Chitin-based nanocomposites are fabricated by various methods, involving electrospinning, freeze drying, etc. This review discusses the progress and new developments in the isolation and physico-chemical characterization of chitin; it also highlights the processing of nanochitin in various composite and functional materials.

“…23,24 Likewise, more flexible and longer cellulose nanofibrils (CNF) have also been considered, [25][26][27] particularly if used in their unmodified forms. [28][29][30][31] Compared with CNC, CNF is noted to have a reduced efficiency as Pickering stabilizer. 32 Some of the reasons for this observation include the larger dimensions (axial aspect) of CNF, together with its inherent tendency for entanglement, 33 and strong hydrophilicity, 34 all of which prevent CNF diffusion and adsorption at oil/water interfaces.…”

We consider the variables relevant to adsorption of renewable nanoparticles and stabilization of multiphase systems, including particle's hydrophilicity, electrostatic charge, axial aspect, and entanglement. Exploiting the complexation of two oppositely charged nanopolysaccharides, cellulose nanofibrils (CNF) and nanochitin (NCh), we prepared CNF/NCh aqueous suspensions and identified the conditions for charge balance (turbidity and electrophoretic mobility titration). By adjusting the composition of CNF/NCh complexes close to net neutrality, we produced sunflower oil-in-water Pickering emulsions with adjustable 2 droplet diameter and stability against creaming and oiling-off. The adsorption of CNF/NCh complexes at the oil/water interface occurred with simultaneous partitioning (accumulation) of CNF on the surface of the droplets in net negative or positive systems (below and above stochiometric charge balance relative to NCh). We further show that the morphology of the droplets and size distribution were preserved during storage for at least 6-months at ambient conditions. This long-term stability was held with a remarkable tolerance to changes in pH (e.g., 3 ~ 11) and ionic strength (e.g., 100 ~ 500 mM). The mechanism explaining these observations relates to the adsorption of CNF in the complexes, counteracting the charge losses resulting from the deprotonation of NCh or charge screening. Overall, CNF/NCh complexes and the respective interfacial nanoparticle exchange greatly extend the conditions favoring highly stable, green Pickering emulsions that offer potential in applications relevant to foodstuff, pharmaceutical, and cosmetic formulations .
