The present invention discloses a low urea-producing and flavor-producing Wickerhamomyces anomalus strain and a use thereof in food production, falling within the fields of wine brewing and food safety. The Wickerhamomyces anomalus of the present invention is obtained by isolating from a liquor fermentation environment (Daqu), is named Wickerhamomyces anomalus CGMCC NO. 12416, and was deposited at China General Microbiological Culture Collection Center on May 6, 2016, with a deposit number of CGMCC NO. 12416. The strain of the present invention has the characteristics of low urea production, flavor production, and tolerance to ethanol and acids, is an excellent strain having a fermentation function, and can be used in brewed wine, distilled liquor and other food fields to ensure food safety.

The invention relates to a process for preparing a reduced calorie beverage or food product employing fermentation of a plant-derived juice or liquid and removing the ethanol therefrom. This invention also relates to an apparatus for performing the process for preparing a reduced calorie beverage or food product and to the reduced calorie juices and juice products created using this process and apparatus.

An alcoholic beverage containing ultrafine bubbles of hydrogen with an antioxidative function is provided that is produced by a reductive fermentation technique of alcohol and contains only a small amount of acetaldehyde. A method and an apparatus of oxidative-reductive fermentation of varieties of alcoholic beverages are provided based on facilitation of proliferation of microorganisms under an oxidative condition and a reductive fermentation technique. The reductive fermentation technique suppresses oxidative degradation of generated pyruvic acid, activate alcohol dehydrogenase, and facilitates production of alcohol from acetaldehyde which is an intermediate product, and a gas exchanging function of the ultrafine bubbles of hydrogen decreases acetaldehyde that remains in a period of alcohol fermentation. The technique facilitates fermentation, increases alcohol yield, decreases acetaldehyde content, and enhances fresh savor, mellow taste and an antioxidative function of an alcoholic beverage.

Methods of separating components traditionally considered as waste material from mold-fermented compositions are described. The waste components can be separated either from unfiltered compositions or from a separation stream separated from a composition. In some embodiments, filamentous fungus used in the production of the mold-fermented composition is specifically targeted for separation. Incorporation of separated waste components into various products are also described herein. In some embodiments, the separated components are used in alternative meat products and other foods designed for human consumption. Separated components can also be used in animal feed, as feed stock for other fermentation processes, or for use in treating food, creating cosmetics, or chemical processes.

The present disclosure discloses a Pichia kudriavzevii and a multifunctional complex microbial inoculant and use thereof, and belongs to the technical field of bioengineering. The Pichia kudriavzevii of the present disclosure has a degrading ability of lactic acid as high as 12.69 g.Math.L.sup.−1, which is 2.04 times that of a type strain. At the same time, the strain can also metabolize ethanol and has an OD.sub.600 of 4.48 after fermentation in a sorghum juice medium at 30° C. and 200 rpm for 3 d. The Pichia kudriavzevii could completely consume 58 g.Math.L.sup.−1 of glucose in the sorghum juice medium after 60 h of fermentation and produce 13.06 g.Math.L.sup.−1 of ethanol. The Pichia kudriavzevii degrades lactic acid and can relieve a lactic acid pressure of a fermentation system and enable Saccharomyces cerevisiae to grow and metabolize to produce wine. In addition, the strain and the microbial inoculant thereof can inhibit the production of filamentous fungi and geosmin and have important use prospects for maintaining homeostasis of a fermentation system and food preservation.

Disclosed are devices and methods that allow for the capture and retention of grain aroma that would otherwise be lost or reduced in distilled spirits production processes. Devices and methods are disclosed that allow for the capture and retention of aromas released during grain heating. Devices and methods are disclosed that allow for the capture and retention of grain aromas prior to the loss of these aromas in subsequent mashing, fermentation, and distillation processes. In one embodiment, captured and retained aromas from a particular grain are added back to the spirit distillate produced from that same grain. In one embodiment, the grain from which aroma is extracted is subsequently mashed, fermented, distilled and rejoined with the aromatized spirit to produce a rejoined spirit. Devices and methods are disclosed which utilize the grain aroma extraction process as a source of heat for the cooking of grain in subsequent or parallel mashes.
