METHOD FOR PRODUCING ALKYL METHYL KETONE, FLAVOR INGREDIENTS CONTAINING SAID ALKYL METHYL KETONE, FLAVOR COMPOSITION CONTAINING SAID FLAVOR INGREDIENTS, AND FOOD CONTAINING SAID ALKYL METHYL KETONE

摘要

The invention relates to a process for producing methyl-alkyl ketones using micro-organisms which convert fatty acids or their esters into the corresponding methyl ketones having one carbon atom less. Suitable micro-organisms are those which produce at least 0.1% w/w methylketones in the culture broth. Preferred micro-organisms are Aureobasidium pullulans species. The process is especially suitable to produce pentan-2-one, heptan-2-one, nonan-2-one and undecan-2-one or mixtures thereof. The compounds produced are suitable for use in food flavours.
