Abstract
A process for manufacturing beer having a reduced content of purine compounds by using wort having a reduced content of purine nucleosides as a result of decomposing purine nucleosides into purine bases by using nucleoside phosphorylase or nucleosidase, or decomposing purine nucleosides into purine bases during fermentation and having the purine bases metabolized by yeast.
Claims19
In a process for manufacturing beer, the improvement comprising providing at least one member selected from the group consisting of an isolated purine nucleoside phosphorylase and an isolated purine nucleosidase to a wort, allowing said at least one member selected from the group consisting of an isolated purine nucleoside phosphorylase and an isolated purine nucleosidase to act on said wort, and employing said wort in a beer manufacturing process.
In a process for manufacturing beer, the improvement comprising providing at least one member selected from the group consisting of an isolated purine nucleoside phosphorylase and an isolated purine nucleosidase to a wort, allowing said at least one member selected from the group consisting of an isolated purine nucleoside phosphorylase and an isolated purine nucleosidase to act on said wort, wherein said at least one member selected from the group consisting of an isolated purine nucleoside phosphorylase and an isolated purine nucleosidase decomposes the purine nucleosides contained in the wort into purine bases, and employing said wort in a beer manufacturing process.
In a process for producing a wort, the improvement comprising providing at least one member selected from the group consisting of an isolated purine nucleoside phosphorylase and an isolated purine nucleosidase to a wort, and allowing said at least one member selected from the group consisting of an isolated purine nucleoside phosphorylase and an isolated purine nucleosidase to act on said wort.
In a process for producing a wort, the improvement comprising providing at least one member selected from the group consisting of an isolated purine nucleoside phosphorylase and purine nucleosidase to a wort, and allowing said at least one member selected from the group consisting of an isolated an isolated purine nucleoside phosphorylase and an isolated purine nucleosidase to act on said wort, wherein said purine nucleosides contained in the wort are decomposed into purine bases to obtain a nucleoside-decomposed wort.
