Jan Hendrik Swiegers has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11162059
    Abstract: It has unexpectedly been found that a low alcohol or alcohol-free beverage, with a flavor profile very close to a beer of at least 4% (vol/vol) alcohol, can be produced by using Pichia kluyveri yeast strains. In particular, Pichia kluyveri yeast strains only use the glucose in the wort, and have the ability of converting this substrate into a high concentration of specific flavor compounds, which are normally produced by Saccharomyces ssp. yeast strains used for the brewing of beer. In this way the Pichia kluyveri yeast strains can be used to produce either a low alcohol or alcohol-free beverage, depending on the glucose levels in the wort. The main flavor compounds produced by Pichia kluyveri in the fermentation of wort are isoamyl acetate, isoamyl alcohol, ethyl butyrate, ethyl hexanoate and ethyl octanoate.

  • Publication number: 20210289820
    Abstract: The invention relates to methods of preparing vegetable juice comprising fermenting a vegetable substrate with a Pichia kluyveri. Fermented vegetable juice obtained according the method has better flavor profiles, in particular reduced earthy flavors. The invention also provides Pichia kluyveri strains useful for fermenting vegetable substrates, which can be further processed to obtain beverages or other consumer products.

  • Patent number: 10544385
    Abstract: It has unexpectedly been found that Pichia spp. strains have advantageous properties useful in the beer fermentation process. In particular, Pichia spp. yeast strains can be combined with normal beer yeast strains and different hop varieties in a fermentation process to produce synergistic effects—namely, the increased production of esters in the fermentation product. More specifically, the yeast can be used to produce increased levels of isoamyl acetate, isobutyl acetate, ethyl propionate, ethyl valerate, ethyl butyrate, ethyl decanoate and ethyl octanoate in beer. In addition, the Pichia spp. strain interacts differently with different hop varieties, so the flavor profile of beer can be tuned by using different combinations of Pichia spp. strains and hops. The present invention relates to a method of brewing beer using a Pichia spp. yeast strain and at least one hop variety, a beer obtainable by such a method and use of a Pichia spp. yeast strain according to the present invention.

  • Publication number: 20130045301
    Abstract: The present invention provides a new wine yeast product in a frozen form. The product is produced in a fermenter, concentrated, cryoprotectants are added. This mixture is then frozen at ?50° C. What makes this product unique is that besides the fact that it is frozen, it can be directly added to grape juice as no rehydration is required because the yeast was not dehydrated in the production process.
