PROCESS FOR PREPARING FLAVOURINGS AND PERFUMES BASED ON ONE OR MORE CAROTENOIDS AS STARTING MATERIAL |
摘要 |
The invention provides a process for preparing flavouring and perfume complexes by converting one or more carotenoids like carotenes, xanthophylls etc. into a reaction product with organoleptic properties in the presence of a liquid solvent or liquid suspension medium containing an oxygen-containing gas at a temperature in the 20-250 DEG C range under a pressure of not more than 400 bar. The obtained products - optionally after a complete or partial removal of the solvent or suspension medium - may be used for the direct or indirect perfuming and flavouring respectively of materials. |
