The present invention relates to a method for oxidizing beta-caryophyllene with oxygen, in particular atmospheric oxygen, which avoids the use of catalysts, enzymes and solvents. Furthermore, the present invention provides a mixture comprising certain caryophyllene oxides as well as their use as a flavor and/or fragrance. The present invention also relates to products and semi-finished products comprising the mixture according to the invention.

Process for preparing caryophyllene oxide

The present invention relates to a new high-throughput process for reducing impurities in essential oils and extracts (in particular for fragrances, fragrance ingredients, flavours and cosmetic ingredients) under mild conditions. Undesirable natural components such as waxes, but also synthetic materials such as agrochemicals and other environmental pollutants are reduced by using at least one selective nanofiltration membrane. In addition, the present invention relates to a method for reducing coloured components in essential oils to obtain a less coloured or even colourless essential oil, while achieving high re-colouration stability over time. Further, the odour quality is maintained or increased through reduction of undesirable olfactory substances to achieve a purified and higher quality oil.

Cold treatment

The present invention relates to a process for producing an ethanol-free vanilla extract, and an ethanol-free vanilla extract obtainable by the process according to the invention. In particular, the present invention relates to an ethanol-free vanilla extract comprising at most 100 mg/kg ethanol, the use of this ethanol-free vanilla extract and products comprising the ethanol-free vanilla extract. The focus of the present invention is in particular to provide an ethanol-free vanilla extract which contains only traces of ethanol naturally contained in fermented vanilla beans and is produced without the use of ethanol.

Production of ethanol-free vanilla extracts

The present invention relates to a process for preparing of a food concentrate in which an aqueous starting solution from a foodstuff is concentrated by osmosis with a semi-permeable biomimetic membrane. In addition, the present invention relates to a food concentrate which can be produced by the process according to the invention, a food concentrate which is free of disturbing aroma components with an OAV (odour activity value) ≥1 and which does not contain any solvent additives. Furthermore, the present invention relates to the use of the food concentrates and products comprising the food concentrate according to the invention.

Production of flavor concentrates by osmosis

The present invention relates primarily to a method for obtaining a volatile fraction from a juice and/or an alcohol-containing beverage, comprising or consisting of the following steps: (a) distilling a mixture of substances from the juice and/or the alcohol-containing beverage, wherein the distillation is performed by a spinning cone column; (b) contacting the mixture of substances from step (a) with a sorbent to obtain a loaded sorbent; and (c) contacting the loaded sorbent from step (b) with a liquid desorbent to obtain the volatile fraction, wherein desired ingredients of the volatile fraction are concentrated as compared to the juice and/or alcohol-containing beverage such that an addition of 0.1% by mass or less of the volatile fraction to any food preparation produces a perceptible odor impression and/or taste impression in a test subject.

Obtaining a volatile fraction from juices or alcoholic beverages

The present invention relates to a mixture comprising or consisting of:

Mixtures having a salty taste
