Abstract: Provided is a method of manufacturing a sparkling alcoholic beverage excellent in properties such as flavor without using hops as part of raw materials. The method of manufacturing a sparkling alcoholic beverage includes: a pre-fermentation step (10) of preparing a pre-fermentation solution by using a germinated legume without using hops as part of the raw materials; and a fermentation step (11) of conducting alcohol fermentation by adding a yeast to the pre-fermentation solution.

Abstract: A selection method for barley lipoxygenase-1 deficient barley, comprising a step of distinguishing the barley lipoxygenase-1 deficient barley by whether or not the guanine at the splicing donor site of the 5th intron of the barley lipoxygenase-1 gene is mutated to a different base; and a method for production of malt alcoholic beverages using a material for malt alcoholic beverages derived from barley obtained by the selection method.

Abstract: Disclosed is a method for producing a sparkling alcoholic beverage having excellent properties including flavor, without using a hop as a part of the raw materials. Specifically disclosed is a method for producing a sparkling alcoholic beverage, which comprises: a pre-fermentation step (10) of preparing a pre-fermentation solution by using a germinated garden pea (Pisum sativum), without using a hop, as a part of the raw materials; and a fermentation step (11) of conducting the alcohol fermentation by adding an yeast to the pre-fermentation solution.

Abstract: The present invention provides a method for determination of the foam stability of a fermented malt beverage, wherein the concentration of yeast thioredoxin (MT) in the fermented malt beverage or a fermenting material solution of the fermented malt beverage is used as an index having a negative correlation with the foam stability of the fermented malt beverage, and the concentration of protein Z (MZ) in the fermented malt beverage or a pre-fermentation or fermenting material solution of the fermented malt beverage is used as an index having a positive correlation with the foam stability of the fermented malt beverage, to determine the foam stability of the fermented malt beverage. According to the determination method of the invention, it is possible to determine the foam stability from the concentration of prescribed proteins in the fermented malt beverage or pre-fermentation or fermenting material solution thereof without directly measuring the head retention of the fermented malt beverage.

Abstract: A method is provided in which a correlation is made between a parameter indicating modification of a sampled malt in a germination process in which barley is germinated, and an ESR signal intensity of the sampled malt. The parameter is determined, in advance, by general analytical methods including chemical analytical methods. The ESR signal intensity is determined by measuring a peak height of spectrum of the sampled malt at a g value at which an unpaired electron derived from a carbon radical is resonant. The ESR signal intensity is a ratio of the measured peak height of spectrum to a peak height of spectrum of a reference, per a unit weight of the sampled malt. The modification state of the sampled malt can be evaluated based on the ESR signal intensity determined by electron spin resonance spectrometry. Kohlbach index, Hartong index at 45° C., diastatic power, ?-glucan content, viscosity, and friability may be used as the parameter.
