“…The stability of CNF and TEMPO‐CNF stabilized emulsion was shown to be more significant than that of CNC due to the longer networks of fibrils formed around droplets resulting in a physical barrier against coalescence [206,207] or electrostatic repulsion for the highly charged fibrils [208] . Bouhoute et al [275] . implemented confocal laser scanning micrography (CLSM) and confirmed the Pickering emulsion formation and stabilization by visualizing the adsorption of MFC at the oil/water interface.…”

“…Two mechanisms were identified to hinder coalescence for higher emulsion stability. The first one was attributed to the single adsorption of argan shell MFC (AS‐MFC) on oil droplets, and the second one was a 3D network surrounding the oil droplets due to the interconnection between the non‐adsorbed and adsorbed fibers [275] . Cellulose filaments (CF) consisting of both fragments and fibrils showed to stabilize medium‐ and high‐internal phase oil‐in‐water Pickering emulsions (MIPEs and HIPEs) by forming a thin layer of CF fibrils surrounding the oil droplets visualized by an optical microscope [276] .…”

The main scope of this Review was the recent progress in the use of plant‐based polymers and particles for the stabilization of Pickering and non‐Pickering emulsion systems. Due to their availability and promising performance, it was discussed how the source, modification, and formulation of cellulose, starch, protein, and lignin‐based polymers and particles would impact their emulsion stabilization. Special attention was given toward the material synthesis in two forms of polymeric surfactants and particles and the corresponding formulated emulsions. Also, the effects of particle size, degree of aggregation, wettability, degree of substitution, and electrical charge in stabilizing oil/water systems and micro‐ and macro‐structures of oil droplets were discussed. The wide range of applications using such plant‐based stabilizers in different technologies as well as their challenge and future perspectives were described.

“…Among the renewable organic fillers, microfibrillated cellulose (MFC) is highly possible as a great candidate for reinforcing NR. MFC has some superior properties that benefit for reinforcement reasons, including high strength, stiffness, and low weight [9]. Owing to its long fibril characteristic, entangled cellulose nanofibers, and interconnected web-like structure, the MFC could improve the composite toughness [10].…”

This study aimed to investigate the effect of epoxidation levels on the curing and tensile properties of epoxidized natural rubber (ENR)/microfibrillated cellulose (MFC) composites. ENRs with different levels of epoxidation were first prepared from natural rubber (NR) latex via ‘in situ’ performic epoxidation using 0.75 M formic acid and 1 M hydrogen peroxide at 50°C at various reaction times. The results from H1 NMR revealed that the reaction at 2, 4, and 6 hours could achieve 20, 30, and 40 mol % epoxidation, respectively. The introduction of epoxide groups into NR chains reduced the scorch and cure time along with the increase of the epoxy content. Furthermore, it was observed that the tensile strength rose remarkably at 30 mol% epoxidation (ENR30). Therefore, the ENR30 was subsequently chosen to prepare the composites with various amounts of MFC (1, 3, and 5 parts per hundred rubber, phr). Interestingly, incorporating MFC elevated tensile strength and elongation at break of ENR30. At 5 phr of MFC, the composite possessed the highest tensile strength and elongation at break value, which reached up to 31.07 MPa and 922.92%, respectively.

“…Plant-derived compounds such as proteins, saponins, polysaccharides and phospholipids have shown promising emulsifying properties in various food applications [2,3]. They can provide similar stabilizing properties as synthetic emulsifiers, but they are also criticized because of their extensive preparation/manufacturing procedures [4][5][6].…”

The surface-active and emulsifying properties of crude aqueous ethanolic extracts from untreated olive oil cake (OOC) were investigated. OOC extracts contained important concentrations of surface-active components including proteins, saponins and polyphenols (1.2–2.8%, 7.8–9.5% and 0.7–4.5% (w/w), respectively) and reduced the interfacial tension by up to 46% (14.0 ± 0.2 mN m−1) at the oil–water interface. The emulsifying ability of OOC extracts was not correlated, however, with their interfacial activity or surface-active composition. Eighty percent aqueous ethanol extract produced the most stable oil-in-water (O/W) emulsions by high-pressure homogenization. The emulsions had average volume mean droplet diameters of approximately 0.4 µm and negative ζ-potentials of about -45 mV, and were stable for up to 1 month of storage at 5, 25 and 50 °C. They were sensitive, however, to acidic pH conditions (<5) and NaCl addition (≥25 mM), indicating that the main stabilization mechanism is electrostatic due to the presence of surface-active compounds with ionizable groups, such as saponins.
