Publication number: 20240409859Abstract: The invention relates to a method of producing a beverage comprising the steps of (a) fermenting a wort using a culture comprising a maltose-negative yeast strain to obtain a fermented beverage having an alcohol content of less than 1.00% v/v; and (b) subjecting the fermented beverage to a thermal dealcoholization step at a temperature between 2° and 80° C. to obtain the beverage.Type: ApplicationFiled: March 31, 2022Publication date: December 12, 2024Applicant: Chr.

Patent number: 11162059Abstract: 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.Type: GrantFiled: September 16, 2019Date of Patent: November 2, 2021Assignee: CHR. HANSEN A/SInventors: Sofie Saerens, Jan Hendrik Swiegers

Patent number: 10544385Abstract: 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.Type: GrantFiled: November 10, 2016Date of Patent: January 28, 2020Assignee: CHR.

Patent number: 9657315Abstract: The present invention relates to recombinant microorganisms comprising an isobutanol producing metabolic pathway and methods of using said recombinant microorganisms to produce isobutanol. In various aspects of the invention, the recombinant microorganisms may comprise one or more modifications resulting in the reduction in the expression and/or activity of an endogenous transporter protein. In various embodiments described herein, the recombinant microorganisms may be microorganisms of the Saccharomyces clade, Crabtree-negative yeast microorganisms, Crabtree-positive yeast microorganisms, post-WGD (whole genome duplication) yeast microorganisms, pre-WGD (whole genome duplication) yeast microorganisms, and non-fermenting yeast microorganisms.Type: GrantFiled: December 21, 2015Date of Patent: May 23, 2017Assignees: VIB VZW, KATHOLIEKE UNIVERSITEIT LEUVEN, K.U.LEUVEN R&DInventors: Catherine Asleson Dundon, Christopher Smith, Piruz Nahreini, Johan Thevelein, Sofie Saerens
