Clove Bud Oleoresin is prepared by solvent extraction of clove bud. This oleoresin is extremely concentrated product which contains more flavoring ingredients that can be soluble in the particular solvent used, as it turns much close to original clove flavor and odor. A concrete, absolute and oleoresin are also produced by the buds in small quantities. However in view to make food safety product, ethanol is generally used as a solvent agent, as this is regarded as non toxic material compared with the other solvents.
