Summary
This review explores enhancing chitosan
Area of Science:
- Biomaterials Science
- Colloid and Surface Chemistry
Background:
- Chitosan, derived from crustacean waste, possesses valuable biological properties.
- Its application is expanding, but high hydrophilicity limits its efficiency as an emulsion stabilizer.
- Improving chitosan's emulsifying capabilities is crucial for broader industrial use.
Approach:
- This review examines strategies to enhance chitosan's emulsifying properties.
- Approaches include structural modification of chitosan and creating complex particles with other compounds.
- Focus is placed on chitosan-based particles for Pickering emulsion stabilization, particularly via electrostatic interactions.
Key Points:
- Chitosan's inherent hydrophilicity hinders its effectiveness as an emulsion stabilizer.
- Structural modification and combination with other materials (polysaccharides, proteins) improve chitosan's emulsifying performance.
- Electrostatic interaction methods are increasingly employed to create advanced chitosan-based stabilizers.
Conclusions:
- Recent research focuses on overcoming chitosan's hydrophilicity for improved emulsion stabilization.
- Combining chitosan with other agents or modifying its structure offers viable solutions.
- Chitosan-based particles show significant promise for stabilizing Pickering emulsions.
