“…Aside from their biocompatibility and abundance, another benefit of utilizing CNCs is that they can be easily modified. Various modification methodologies, encompassing covalent bonding through the insertion of functional chemical groups or surface active species (surfactants, polymers, or proteins) and non-covalent bonding through physical interactions such as electrostatic interaction, hydrogen bonding, and van der Waals force, have been developed to tailor their characteristics and enhance the emulsion stability (Hu et al, 2015b;Bai et al, 2018;Liu et al, 2018;Pindáková et al, 2019;. The CNCs functionalization controls the type of emulsion.…”

Over the past few years, nanocellulose (NC), cellulose in the form of nanostructures, has been proved to be one of the most prominent green materials of modern times. NC materials have gained growing interests owing to their attractive and excellent characteristics such as abundance, high aspect ratio, better mechanical properties, renewability, and biocompatibility. The abundant hydroxyl functional groups allow a wide range of functionalizations via chemical reactions, leading to developing various materials with tunable features. In this review, recent advances in the preparation, modification, and emerging application of nanocellulose, especially cellulose nanocrystals (CNCs), are described and discussed based on the analysis of the latest investigations (particularly for the reports of the past 3 years). We start with a concise background of cellulose, its structural organization as well as the nomenclature of cellulose nanomaterials for beginners in this field. Then, different experimental procedures for the production of nanocelluloses, their properties, and functionalization approaches were elaborated. Furthermore, a number of recent and emerging uses of nanocellulose in nanocomposites, Pickering emulsifiers, wood adhesives, wastewater treatment, as well as in new evolving biomedical applications are presented. Finally, the challenges and opportunities of NC-based emerging materials are discussed.

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.

“…Studies have shown that the combination of proteins and polysaccharides as the stabiliser improved the oxidative stability and physical stability of emulsions formed (Li et al, 2017;Xu et al, 2017a). Previous studies have shown that the SC/CNC-stabilised emulsions were formed due to the higher surface activity of SC and irreversibility of adsorption of CNC at pH 7 (Pinďáková et al, 2019). However, the use of SC/CNC biopolymeric mixture has not been explored in greater depth for both physical and oxidative stability improvement of palm-oleinbased Pickering emulsions in the literature.…”

This work investigated the use of a dual biopolymer system containing cellulose nanocrystals (CNC) and sodium caseinate (SC) for red palm olein-in-water (O/W) Pickering emulsion stabilisation. The effect of CNC particle concentration at a constant amount of SC on emulsion properties was particularly studied.The resultant mixed biopolymer-based emulsions were characterised for droplet size distribution, zeta potential, creaming index and microstructure, as well as primary and secondary oxidation products by oxidation tests at 90˚C. Results showed that creaming stability was relatively high for SC/CNC-stabilised emulsions compared to emulsions prepared with SC alone. Increasing CNC concentration from 0.25% to 1.00% (w/v) resulted in a gradual decrease in emulsion droplet size with increased surface negative charges. Higher CNC content induced a marked reduction in the lipid oxidation of SC/CNC-stabilised emulsions. The mixed SC/CNC biopolymer significantly improved the carotene retention of emulsions during the accelerated oxidation test. Emulsions comprising 1.00% SC and 1.00% CNC presented the highest negative surface charge, lowest peroxide value (PV), p-anisidine value (p-AV), free fatty acid (FFA) value, and total oxidation value (TOTOX). The use of CNC imparted beneficial effects on reducing lipid oxidation and enhancing the stability of palm-based O/W emulsions stabilised by SC.
