Abstract: A process is disclosed for producing beers having yeast turbidity, in particular wheat beer, in which it is possible to metabolize virtually completely the oxygen which has unavoidably passed into the container during packaging, and nevertheless to perform continuous pasteurization integrated into the filling device. For this purpose, prior to packaging, yeast and beer wort are again added to the beer, and the yeast in the beer present in a package is destroyed within 24 hours of packaging. By this means, sterile beer having very high flavor stability can be produced, which is also suitable for sale of canned beer and for export even to distant countries.

Abstract: The present invention provides refrigeratable yeast-leavened dough compositions and methods of making such doughs. In a first embodiment, a dough composition of the invention is made by rehydrating dried yeast at chilled temperatures, which causes selective lysing (a loss in the selectivity of the yeast plasma membrane). Such a dough composition exhibits a cold sensitivity in that the yeast is capable of leavening the dough at elevated temperatures, but becomes inactive at refrigeration temperatures. In another embodiment, the dough composition and the strain of yeast used therein are chosen to limit the total leavening action of the yeast by controlling the amount of substrate in the dough fermentable by the yeast. In a third embodiment, a dough comprises a mixture of flour, water and a mutant yeast which is low temperature sensitive. Such an "lts" yeast is active at elevated temperatures, but becomes substantially inactive at refrigeration temperatures.

Abstract: A beverage containing sugar is carbonated by first placing the beverage and a small amount of yeast in a bottle. A small paper disk impregnated or coated with a yeast-killing sterilizing agent such as sodium metabisulfite is attached to the underside of a bottle cap. The bottle is then sealed with the cap and stored in an upright position with the bottle cap holding the disk above the beverage. After the yeast has fermented a sufficient amount of the sugar to adequately carbonate the beverage, the bottle is shaken for a time to allow the beverage to rinse the yeast-killing agent from the disk. As the agent mixes with the beverage, it kills the yeast in the bottle, thereby terminating fermentation of the sugar.

Abstract: An improved, short-time process for fermentation of comestible products is described which enhances the growth of operative microorganisms in a fermentation system and consequently reduces the required incubation time. The process involves inoculating a given fermentation system containing a starting food ingredient substrate and fermentative microorganism(s) with an amount of an oxygen-reactive enzyme such as OXYRASE.TM.
