The invention provides a preparation method of
fructus phyllanthi powder. The method comprises the following specific steps: washing fresh
fructus phyllanthi fruits, and crushing the washed fresh
fructus phyllanthi fruits; diluting a biological
enzyme with drinking water; adding crushed fructus phyllanthi into a container, adding the diluted biological
enzyme liquid into the container, stirring and uniformly mixing the crushed fructus phyllanthi and the diluted biological
enzyme liquid, heating and carrying out heat insulation; separating a fructus phyllanthi enzymolysis solution, and filtering by virtue of a filter cloth, thus obtaining a primary filtrate; filtering the primary filtrate with a
ceramic film; adsorbing by virtue of
macroporous resin and eluting; and
drying so as to obtain the fructus phyllanthi
powder. According to the invention, the
biological activity of the biological enzyme is utilized for enzymolyzing the
pectin,
starch and
cellulose contained in the crushed fresh fructus phyllanthi fruits into glycose, so that the tissues of the crushed fresh fructus phyllanthi fruits to form gaps which are beneficial to the
dissolution of
active components; an enzyme
hydrolysis technology adopted in the invention can be used for improving the yield and comprehensive
utilization rate of the fructus phyllanthi
powder and reducing the production cost; the enzyme
hydrolysis macroporous resin, cryoconcentration, low-temperature
spray drying technologies are applied, so that damages or losses of thermo-sensitivity components such as natural
vitamin C (VC) and the like are reduced, thus the contents of the VC and other main components in the product are improved, the product quality is stable, and the possibilities of
moisture absorption and discoloration are small; and the method has the advantages that the design is reasonable, the process is advanced, the product quality is high, the product taste is good, and the
raw material utilization ratio is high.
