Low temperature fermentation accelerator of yeast, as well as a method for producing fermented foods and drinks and yeast growth medium using the same

摘要

Such as foaming alcoholic beverage, an object of the present invention that if the yeast fermentation at low temperature is carried out during manufacture, have a problem that fermentation efficiency decreases by slowing proliferation activity of the yeast. Was found to exhibit the effect of peptides fractionated rich fractions to β- conglycinin is a kind of globulin from soy protein, were digest and this fraction is significantly enhanced low-temperature growth ability of the yeast. That is, the present invention is a low temperature fermentation promoter of yeast, characterized in that it comprises a decomposition product of soybean conglycinin β-.
