摘要:
The present invention concerns a process for the production of a beverage (21) said process comprising the following steps: (a) contacting a base liquor (1) containing at least one fermentable sugar with a yeast (2) of the species Pichia, to carry out fermentation under aerobic conditions of said at least one fermentable sugar until an ethanol containing concentrated precursor (11) is formed, comprising an amount of isoamyl acetate (IAAT) of at least 10 ppm, or an amount of ethyl acetate of at least 90 ppm, wherein, unless otherwise indicated, the amounts in ppm are expressed with respect to the total weight of the concentrated precursor; (b) blending the thus obtained concentrated precursor as such (11) or after further treatment (11a), with more than 50 vol/% of a dilution liquor (12) to produce said beverage (21) having an IAAT content of at least 0.5 ppm with respect to the total weight of the beverage.
摘要:
The invention relates to an alcoholic fermentation process in the presence of one or more high alcohol tolerant yeast and one or more maltotriose positive yeast. The process of the present invention can be a fermentation process for the production of ethanol, for the production of beer, for the production of wine and the like. in a preferred embodiment, the present invention relates to a process for the production of ethanol in the presence of distiller's yeast and baker's yeast.
摘要:
The present invention relates to a gene encoding a catalase and use thereof, in particular, a brewery yeast having high sulfite-producing capability, alcoholic beverages produced with said yeast, and a method for producing said beverages. More particularly, the present invention relates to a yeast, whose capability of producing sulfite, that contribute to stability of flavor in products, is enhanced by amplifying expression level of CTT1 gene encoding a catalase Ctt1p, especially non-ScCTT1 gene or ScCTT1 gene specific to a lager brewing yeast, and to a method for producing alcoholic beverages with said yeast.
摘要:
The present invention relates to a brewery yeast having controlled hydrogen sulfide-producing capability, a process for producing alcoholic beverages with controlled hydrogen sulfide amount. More particularly, the present invention relates to a yeast whose hydrogen sulfide-producing capability that increases the product flavor is controlled by enhancing the expression level of YGR012W gene encoding brewery yeast cysteine synthase Ygr012wp, particularly non-ScYGR012W gene specific to lager brewing yeast, and to a method for producing alcoholic beverages with said yeast.
摘要:
Ein Getränk wird mit einem Verfahren hergestellt, bei dem eine teilweise vergorene Flüssigkeit mit einem ersten Hefestamm und eine teilweise vergorene Flüssigkeit mit einem zweiten Hefestamm zusammen gegeben werden. Hierbei sind die zwei Flüssigkeiten Jungbiere und der erste Hefestamm eine obergärige und der zweite Hefestamm eine untergärige Hefe. Durch dieses Verfahren und vorteilhafte Ausführungsvarianten des Verfahrens wird erreicht, ein Getränk herzustellen, bei dem positive gewünschte Stoffe angereichert sind, während unerwünschte negative Stoffe abgereichert sind.
摘要:
It is intended to provide a method of identifying a gene of a yeast for brewing which participates in the flavor of an alcoholic drink and control the expression of this gene to thereby enable the production of an alcoholic drink having a desirable flavor. To achieve the above object, a method of identifying a yeast for brewing by using a gene analysis means comprising a DNA array optionally together with two-dimensional electrophoresis, a DNA array having the thus identified gene attached thereto, and a method of selecting a yeast for brewing with the use of this DNA array are provided.
摘要:
The present invention relates to ammonia transporter genes and use thereof. The invention relates in particular to a brewer's yeast which shows enhanced ammonia assimilation, alcoholic beverages produced using such yeast, and a method of producing such alcoholic beverages. More specifically, the invention relates to the MEP1 gene which codes for the ammonia transporter Mep1 in brewer's yeast, particularly to a yeast which can control the ammonia assimilation ability by controlling the level of expression of the nonScMEP1 gene or ScMEP1 gene characteristic to beer yeast and to a method of producing alcoholic beverages using such yeast.
摘要:
The present invention relates to a gene encoding a protein having a trehalose synthesis-promoting activity and use thereof, in particular, a yeast for practical use with superior resistance property to dryness and/or low-temperature storage, alcoholic beverages produced with said yeast, and a method for producing said beverages. More particularly, the present invention relates to a yeast, whose resistance property to dryness and/or resistance property to low-temperature storage is enhanced by amplifying expression level of TSL1 gene encoding a protein Tsl1p having a trehalose synthesis-promoting activity in brewer's yeast, especially non-ScTSL1 gene specific to a lager brewing yeast and to a method for producing alcoholic beverages with said yeast, etc.
