Citral-loaded oil-in-water Pickering emulsions were fabricated with chitosan-tripolyphosphate particles (CS-TPP Ps) as stabilizers using a high-shear rotor homogenizer. The influence of the contents of CS-TPP Ps on the physical and chemical properties of the Pickering emulsions was investigated at 40 °C for 14 days. The morphology and chemical stability of the citral-loaded Pickering emulsions were determined by laser diffraction, optical microscopy, confocal laser scanning microscopy and solid-phase microextraction-gas chromatography (SPME-GC). Results showed that the droplet size of the Pickering emulsions decreased from 14.4 to 11 μm as the concentration of CS-TPP Ps increased. The droplet size of the Pickering emulsion with 0.6% w/v CS-TPP Ps remained unchanged during storage. GC illustrated that the Pickering emulsion with 0.6% w/v CS-TPP Ps showed the best chemical stability, with 52.33% citral remaining after 14 days of monitoring. Overall, the encapsulation of citral in CS-TPP Ps Pickering emulsions enhanced its chemical stability in acidic surroundings.

UI	MeSH Term	Description	Entries
D010316	Particle Size	Relating to the size of solids.	Particle Sizes,Size, Particle,Sizes, Particle
D002849	Chromatography, Gas	Fractionation of a vaporized sample as a consequence of partition between a mobile gaseous phase and a stationary phase held in a column. Two types are gas-solid chromatography, where the fixed phase is a solid, and gas-liquid, in which the stationary phase is a nonvolatile liquid supported on an inert solid matrix.

D004655	Emulsions	Colloids formed by the combination of two immiscible liquids such as oil and water. Lipid-in-water emulsions are usually liquid, like milk or lotion. Water-in-lipid emulsions tend to be creams. The formation of emulsions may be aided by amphiphatic molecules that surround one component of the system to form MICELLES.	Emulsion
D005404	Fixatives	Agents employed in the preparation of histologic or pathologic specimens for the purpose of maintaining the existing form and structure of all of the constituent elements. Great numbers of different agents are used; some are also decalcifying and hardening agents. They must quickly kill and coagulate living tissue.	Fixative,Pickling Agents,Agents, Pickling
