The invention provides fat-burning dredging particles and a preparation method thereof. The fat-burning dredging particles are prepared by the following raw materials through the following steps: a smashing
curcuma zedoary, roasted rhizoma atractylodis macrocephalae and
pericarpium citri reticulatae, screening mixed
powder through a third-level screen, supercritically extracting volatile oil of the mixed
powder through
carbon dioxide (CO2), performing beta-CD inclusion on the volatile oil through a saturated water solution method, refrigerating for 12-30 hours, leaching to obtain beta-
cyclodextrin inclusion complex of the volatile oil, and keeping the beta-
cyclodextrin inclusion complex of the volatile oil for use; b smashing 50-70% of
coix seeds by weight, screening
powder of the
coix seeds through a sixth-level screen and keeping
fine powder for use; c smashing
pinellia ternate, rhizoma alismatis,
typha angustifolia, Chinese rhubarb, radix clematidis and the rest of the
coix seeds into coarse powder, performing
alcohol extraction on the coarse powder and the residue remained after the volatile oil is supercritically extracted out of the
curcuma zedoary, the roasted rhizoma atractylodis macrocephalae and the
pericarpium citri reticulatae for twice, combining
alcohol extract, condensing and
drying to obtain extractum; and d smashing dried extractum, mixing the smashed extractum with the coix seed
fine powder obtained in the b step, screening the mixture through a sixth-level screen, adding the beta-CD inclusion complex obtained in the a step and steviosin into the screenedmixture, evenly mixing the mixture, conventionally palletizing the mixture, and split charging to obtain the fat-burning dredging particles.
