The invention relates to a preparation method of
arenga pinnata
powder. The preparation method comprises the following steps of (1) taking
arenga pinnata piths; (2) performing dicing; (3) performing crushing; (4) performing squeezing to obtain juice; (5) performing
drying; (6) performing allocation; and (7) performing packing. The preparation method of the
arenga pinnata
powder comprises the special steps of putting
pith slices under the high-temperature high-pressure state for
drying, so that an
arenga pinnata stock solution in the
pith slices can be extruded into the outer surfaces of the
pith slices, and the yield of the
arenga pinnata powder can be increased; adding an appropriate quantity of fresh bean dregs in the pith slice powder, and then performing squeezing to obtain juice, so that accompanied
pigment in the
arenga pinnata stock solution can be effectively removed, and the made wet
starch is purely white; putting the wet
starch after performing squeezing in sunshine, and performing
drying in the sunshine, so that the powdery arenga pinnata initial powder is obtained, and running off of beneficial components in the arenga pinnata initial powder can be effectively reduced;adding an appropriate amount of white granulated
sugar and an appropriate amount of
lotus seed powder to the powdery arenga pinnata initial powder, so that the arenga pinnata powder is delicious andrefreshing in mouth feel, and besides, the effects of removing dampness and reducing internal heat of the arenga pinnata powder can be greatly increased, and the arenga pinnata powder has good
efficacy of reducing weight, and beautifying the features.
