Mint-type flavour oils, compositions containing them and processess for their preparation

摘要

Improved flavor oils, such as spearmint and peppermint oils, are prepared by extraction of common plant materials at a low temperature with high pressure using carbon dioxide as a solvent. The flavor oils prepared by the supercritical extraction process demonstrate enhanced organoleptic qualities, greater stability and shelf-life, and prolonged flavoring agent properties. In particular, these novel oils provide true mint leaf-type flavors and aromas which have more upfront sensory impact than conventional oils, enhanced aroma and flavor stability, reduced oxidative degradation properties and consequent cost savings and enhanced consumer acceptance. They may be used in a wide variety of compositions.
