  • Patent number: 11937622
    Abstract: 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.

  • Publication number: 20210122995
    Abstract: 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.
