Abstract
The present invention a method for simultaneously reducing urethane and its precursors levels during Chinese liquor production process, which relates to the field of fermented food production. The present invention is carried out through inoculating Bacillus amyloliquefaciens JP21 or combines with urease into the grains for fermentation. The content of EC and urea in the fermented grains after 5-day fermentation could reduce 30.16% and 50.05% respectively, With an addition of the B. amyloliquefaciens during grains fermentation, EC and urea levels are successfully controlled, and at the same time aroma and tastes of Chinese liquor hasn't been affected.
