The invention discloses a coarse cereal
food processing method based on biological
enzyme-
physical field coupling, and belongs to the technical field of coarse cereal
food processing and utilization. The preparation method comprises the following steps: firstly, mixing pure coarse cereal
powder with a compound modified material, and premixing to obtain a premix; adding deionized water, a compound flavourzyme solution and
carboxymethyl chitosan into the premix for enzymolysis, performing ultrasonic and pulsed
electric field cooperative treatment after enzymolysis is finished, performing vacuum concentration
after treatment, adding
trehalose and modified diatomite, and uniformly mixing to obtain a
coupling modified material; then kneading dough, adding food-grade
glycerol during dough kneading, rolling, and
cutting into strips to obtain noodle blanks; and finally, carrying out gradient
drying on the noodle blanks, introducing
nitrogen in the
drying process, and obtaining the
brewing instant coarse cereal noodles after the
drying is finished. The method effectively solves the problems of non-uniform rehydration, unstable forming, high storage
embrittlement rate, turbid soup and the like of the
brewing instant coarse cereal noodles, and meets the industrial production requirements of the
brewing instant coarse cereal noodles.
