A novel cinnamaldehyde essential oil (CEO)/β-Cyclodextrin (β-CD) composite was developed, showing enhanced emulsion stability. The composite formed a stable network structure, improving Pickering emulsion properties.
Area of Science:
- Food Science and Technology
- Materials Science
Background:
- Cinnamaldehyde essential oil (CEO) has potential applications but requires stabilization.
- β-Cyclodextrin (β-CD) is a known host molecule for encapsulating active compounds.
Purpose of the Study:
- To prepare and characterize a CEO/β-CD composite.
- To investigate the properties of Pickering emulsions stabilized by β-CD and CEO/β-CD.
Main Methods:
- Preparation and characterization of CEO/β-CD composite using FT-IR and XRD.
- Comparative study of Pickering emulsions stabilized by β-CD and CEO/β-CD at varying concentrations (1-5%).
- Evaluation of emulsion stability, rheology, and microstructure using fluorescence and scanning electron microscopy (SEM).
Main Results:
- A CEO/β-CD composite with a high embedding rate (91.74%) was successfully prepared.
- CEO/β-CD emulsions exhibited superior storage stability compared to β-CD emulsions.
- Rheological analysis indicated gel-like elastic and shear-thinning behavior for both emulsion types.
- Microstructural analysis revealed different stabilization mechanisms: crystalline β-CD shells versus a networked aqueous phase for CEO/β-CD composites.
Conclusions:
- The CEO/β-CD composite effectively enhances the stability of Pickering emulsions.
- The distinct microstructural arrangements of β-CD and CEO/β-CD composites lead to differences in emulsion properties and droplet size dynamics.

Stability of Substituted Cyclohexanes
The two chair conformations of cyclohexanes undergo rapid interconversion at room temperature. Both forms have identical energies and stabilities, each comprising equal amounts of the equilibrium mixture. Replacing a hydrogen atom with a functional group makes the two conformations energetically non-equivalent.
