The invention relates to a method for preparing barley maltsyrup by using
wheat flour. The method comprises the following steps: after
wheat gluten is extracted from
wheat flour, screening obtained
starch milk; concentrating the
starch milk by a concentration separator; conditioning the
starch milk; adjusting the pH value of the starch milk; introducing high temperature resistant alpha-
amylase forspray
liquefaction, laminar insulation and cooling on the starch milk; saccharifying the starch milk by saccharifying
enzyme, and inactivating
enzyme; adding flocculant and filter aid for
filtration;decoloring the starch milk by adding
activated carbon; filtering the starch milk to obtain clear filtrate; carrying out cation resin exchange and
cathode resin exchange of the filtrate; reducing pressure and distilling the filtrate; inspecting quality of the filtrate; measuring and packaging the filtrate. The method solves the problems that the syrup cannot be filtered, and the finished product syrup has poor
clarity in a process for manufacturing a finished product barley maltsyrup by using wheat A-type starch and B-type starch. The method saves rectification separation and
drying processesof starch, and reduces the numbers of
liquefaction times in sugaring, improves the syrup yield by 15 percent, has simple process and standard syrup quality, and reduces manufacturing cost and environmental
pollution.
