The invention discloses a preparation method of
starch-free enzymolysis
corn flour. The preparation method comprises the following steps: pre-crushing, cooking, defibrination, enzymolysis,
filtration, concentration, homogenization, sterilization,
spray drying, and packaging. The preparation method provided by the invention specifically comprises the steps of pre-crushing corn grains firstly, then putting the crushed corn grains into a cooking kettle for preliminary cooking, then adding
sodium tripolyphosphate and
sodium citrate, and passing the mixture through a
colloid mill; and adding medium-temperature alpha-
amylase into an enzymolysis tank for enzymolysis, lowering the temperature, adding
cellulase for enzymolysis, adding
sodium D-isoascorbate and
sodium bicarbonate after enzymolysis, performing
filtration, concentration, homogenization and sterilization, and finally, performing
spray drying to prepare the enzymolysis
corn flour. The
starch in corns is thoroughly removed from the enzymolysis
corn flour prepared by the method, the
mouthfeel is significantly improved, and the phenomenon of
retrogradation agglomeration in a later period of a corn beverage can also be solved.
