The invention relates to a method for
brewing vinegar in one step through saccharification and
alcohol fermentation and belongs to the method for
brewing the vinegar. The method includes the steps of screening and cleaning corn kernels, carrying out degerming on the corn kernels, keeping skins of the corn kernels, smashing the core kernels with the skins to obtain high-
fiber corn flour in a certain grain size, adding water into the
corn flour according to a certain material-to-water ratio to make into
corn flour milk with a certain concentration, carrying out high-temperature
processing, high-shear
processing, gelatinizing, liquifying, sterilizing, cooling, smashing and mixing on the corn flour milk, adding
amylase and
saccharomyces cerevisiae into the corn flour milk to carry out saccharification and
alcohol fermentation, and completing saccharification and vinegar and
alcohol fermentation in one step. By adoption of the method, water and time are saved,
energy consumption is low, the production environment is clean, the
production cycle is greatly shortened, and production efficiency is improved. In the production process, conditions are mild, no
pollution and no hazardous substances generate, any chemical
reagent is not used, and products are convenient and safe to use.
