Abstract
It is an object of the invention to provide a process for easily producing a glucan, which assures a high degree of safety and which does not generate an oxidation off-flavor, without using a hydroxide of an alkali metal such as sodium hydroxide. In a process of the present invention, a physically pulverized yeast is autolyzed with an intracellular enzyme thereof, in an electrolyzed alkaline water which is obtained by electrolyzing water.
Claims19
A process for producing a yeast-derived glucan, comprising:
- autolyzing a physically pulverized yeast with an intracellular enzyme thereof, in an electrolyzed alkaline water having a pH within a range of 8.5-11.5 obtained by electrolyzing water, while the yeast is enzyme-treated by adding an alkaline protease to the yeast to produce said glucan, wherein said process is carried out in the absence of a hydroxide of an alkali metal.
A process for producing a yeast-derived glucan, comprising the steps of:
- preparing a mixture by adding a yeast and an alkaline protease to an electrolyzed alkaline water having a pH within a range of 8.5-11.5, wherein the electrolyzed alkaline water is obtained by electrolyzing water;
- physically pulverizing the yeast in thus obtained mixture;
- and
- autolyzing the yeast with an intracellular enzyme thereof, and simultaneously enzyme-treating the yeast with the alkaline protease to produce said glucan, wherein said process is carried out in the absence of a hydroxide of an alkali metal.
A process for producing a yeast-derived glucan, comprising:
- adding an alkaline protease for an enzyme treatment to a physically pulverized yeast in an electrolyzed alkaline water having a pH within a range of 8.5- 11.5 obtained by electrolyzing water, wherein said protease is added immediately after the yeast is physically pulverized, so that autolysis of the yeast with an intracellular enzyme thereof and enzyme-treatment are simultaneously effected to produce said glucan, wherein said process is carried out in the absence of a hydroxide of an alkali metal.
