Paprika oleoresin From the time the first batch of Oleoresins rolled out of our factories in 1972 to date, Synthite has been at the forefront of the evolving food industry. Oleoresins are pure extracts of a spice or herb. They are concentrated natural liquid flavourings that contain both volatile and non-volatile flavour components. Oleoresins provide flavour profiles characteristic of the ground spice or herb with a more rapid flavour release. Our Oleoresins are produced with the finest spices from around the world; they preserve the robust flavour and aroma of the spice.
