“…Similarly, in situ covalent cross-linking of chitosan with CA during homogenization was used to enhance the emulsifying properties of the chitosan (Chen et al, 2017). The CA molecules can form covalent bonds with chitosan chain to form an amphiphilic conjugate.…”

“…Also, the CA molecules can covalently cross-link the chitosan chains at the oil droplet surfaces, causing the creation of a rigid surface that can stabilize NE against coalescence ( Figure 5). Chen et al (2017) addressed three potential advantages of their developed approach: (1) emulsifiers can be formed from all-natural components without the need for synthetic emulsifiers or organic solvents; (2) only a low level of CA is needed, which could be replaced by cinnamon oil; and (3) high stability to droplet coalescence is achievable.…”

In recent years, substantial consideration within the food industry has been aimed at the development of food‐grade nanoemulsions (NE) as promising systems for encapsulating, stabilizing, and delivering bioactive compounds. Although numerous studies have revealed the critical potential of NE, there are still several challenges to overcome them. These include the extensive amounts of synthetic emulsifiers needed for NE formulation, which can potentially be toxic for human health. The interest in safety, and natural emulsifiers have stimulated food manufacturers to develop "label‐friendly" formulations by replacing synthetic emulsifiers with natural alternatives. This review represents a critical and comprehensive summary of the application of natural emulsifiers as potential substitutes for synthetic emulsifiers in NE production, with particular emphasis on the newly identified natural emulsifiers. Some recent reports showed the excellent emulsifying properties of various natural emulsifier extracted from natural resources, to produce NE, and therefore, might be generalized for further industrial applications. Future trends are encouraged to identify novel natural emulsifiers from industrial food by‐products that may demonstrate highly effective emulsifiers.

“…Addition of whey protein microgels and bacterial cellulose is another solution recently published to impart yield stress to the dispersing phase and overcome the emulsion coalescence [164,165]. The second factor is frequently manipulated by increasing the rigidity or elasticity of the interface to reduce the merging of droplets [166,167]. Polymers such as cellulose esters and poly(N-isopropylacrylamide) have been used for this purpose, the latter being triggerable by temperature changes due to its characteristic LCST phase transition [168,169].…”

Hydrogels have been broadly studied for applications in clinically motivated fields such as tissue regeneration, drug delivery, and wound healing, as well as in a wide variety of consumer and industry uses. While the control of mechanical properties and network structures are important in all of these applications, for regenerative medicine applications in particular, matching the chemical, topographical and mechanical properties for the target use/tissue is critical. There have been multiple alternatives developed for fabricating materials with microstructures with goals of controlling the spatial location, phenotypic evolution, and signaling of cells. The commonly employed polymers such as poly(ethylene glycol) (PEG), polypeptides, and polysaccharides (as well as others) can be processed by various methods in order to control material heterogeneity and microscale structures. We review here the more commonly used polymers, chemistries, and methods for generating microstructures in biomaterials, highlighting the range of possible morphologies that can be produced, and the limitations of each method. With a focus in liquidliquid phase separation, methods and chemistries well suited for stabilizing the interface and arresting the phase separation are covered. As the microstructures can affect cell behavior, examples of such effects are reviewed as well.

“…investigated the creaming and coalescence of the emulsion prepared by modified chitosan at pH value ranging from 1.0 to 6.5, by cinnamaldehyde. They found that the natural essential oil can covalently modify the chitosan, which can raise the efficiency of the emulsifying process and stabilize the o/w emulsion . Dammak and Sobral researched the effect of different biopolymers on the stabilization of o/w emulsion.…”

Modified Chitosan as a “Multi‐subtype” Macromolecular Emulsifier for Preparing Asphalt Emulsion

et al. 2019

The “Multi‐subtype” macromolecular cationic asphalt emulsifier was synthesized based on chitosan (abbreviated as MCTS) via the ring‐opening reaction and quaternization. Then the structure of the emulsifier was characterized by FTIR and 1H‐NMR spectra. Moreover, the surface tension and critical micelle concentration (CMC) of the MCTS were determined from 298 to 313 K. The CMC and γcmc were 0.064 g L−1 and 38.85 mN m−1 at 298 K, respectively, and the lowest surface tension of the solution reached to 26.09 mN m−1 at 313 K. The tested Hydrophile‐Lipophile Balance (HLB) value of MCTS was 10, which can meet the requirement of asphalt emulsifier. Through emulsification experiments, the emulsifying ability of the MCTS was measured, and the results indicated that the emulsifier exhibited excellent application for asphalt. It may be caused by that the MCTS containing polar bundle groups could enhance the interaction between polar asphaltene and the emulsifier solution. Moreover, the prepared asphalt emulsion was more stable compared to the emulsion prepared by Gemini emulsifier. The demulsification experiments were also correspondingly done for emulsified asphalt. All the results showed that the MCTS has potential applications in the preparation of asphalt emulsion.
