Manufacturing Processes

Oleoresin Extraction 

One of the core product ranges for Lionel Hitchen (Essential Oils) Limited is oleoresins.

High-quality herbs and spices are selected, ground and extracted using various polar and non-polar solvents. The solvent is then distilled off under vacuum to produce a highly concentrated oleoresin with all the flavour and pungency characteristics of the fresh herb or spice. Oleoresins are highly stable compared to fresh herbs and spices, with the added advantage of being extremely resistant to microbiological contamination.
