  • Patent number: 5130157
    Abstract: The present invention relates to a process for obtaining an aroma concentrate that is enriched in lactones. The present invention is particularly concerned with a process for concentrating lactones from a distillate obtained by the distillative deacidification of a fat composition rich in lauric acid residues, said distillate containing at least 0.1 wt. % of lactones having 6-20 carbon atoms, by subjecting the distillate or a fraction thereof to a fractional distillation so as to obtain a fraction containing at least 1 wt. % of lactones having 6-20 carbon atoms.The present invention offers a commercially and technically attractive route for obtaining natural lactones.Other aspects of the present invention are a lactone concentrate obtainable by the above process, the use of such a concentrate for flavoring food products and to food products flavored by such a lactone concentrate.
