Oleoresins & essential oils

Spice oleoresins and essential oils for the food, flavour and fragrance industries — plus standardised herbal oleoresins.

Spice Oleoresins & Essential Oils

Concentrated flavour, colour and aroma

Oleoresins concentrate the flavour, pungency and colour of a spice into a standardised, easy-to-dose liquid; essential oils carry its volatile aroma. CTA processes the major culinary spices into both.

Herbal Oleoresins

Standardised herbal oleoresins

How They Are Made

Extraction & distillation

Oleoresins are produced by solvent extraction of the dried spice, followed by solvent recovery to leave a concentrated resin standardised to a colour value, volatile-oil content or active marker. Essential oils are produced by steam distillation of the aromatic plant material.
