This invention discloses a method for improving the quality of
aleurone layer and
aleurone-rich
wheat flour using cold
plasma technology. The
aleurone layer
powder preparation method includes wheat cleaning; preparing PAW (pasteurized wheat
bran) using a cold
plasma generator; activating water-soaked wheat with cold
plasma; dehulling the soaked wheat grains using a wheat dehulling
machine, collecting the tissue from the dehulling process to obtain aleurone layer
powder, and collecting the grains after the aleurone layer has been removed;
processing the aleurone layer
powder in a
dielectric barrier
discharge (DBD) type cold
plasma treatment device; and preparing aleurone-rich
wheat flour by adding the aleurone layer powder to
wheat flour at a dosage of 5% to 20%. This invention improves the complete separation of the
bran and aleurone layer through PAW soaking, increases the purity of aleurone layer powder and flour, reduces the load of subsequent cleaning, sieving, and air classification, reduces reliance on high-energy-consuming equipment such as cleaning machines, thereby reducing milling
energy consumption and improving production efficiency.
