The application provides a preparation method of
astaxanthin cordyceps militaris fine tablets, comprising the following steps: subjecting
cordyceps militaris fruiting bodies to supercritical CO2 extraction treatment to separate a
cordyceps militaris
terpene component; mixing
Haematococcus pluvialis
powder and edible
vegetable oil, adding the
cordyceps militaris terpene component and
rosemary extract, and cooling and forming to obtain an
astaxanthin-
cordyceps militaris terpene blend; crushing the residue after extraction, adding
purified water and a composite
enzyme preparation to perform enzymolysis to obtain an enzymolysis liquid; adding a
chitosan quaternary ammonium salt solution, centrifuging after
flocculation,
vacuum drying, and crushing to obtain
cordyceps militaris active
powder; mixing and granulating raw materials to obtain
granulation particles; uniformly mixing the
granulation particles with
xylitol and
microcrystalline cellulose, and pressing into tablets; and placing the tablets in a
coating machine for
coating. The application realizes efficient retention of active ingredients, improvement of safety and stability of product quality through the cooperation of multiple technologies such as supercritical CO2 extraction, enzymolysis
flocculation, low-temperature
fluidized bed granulation and
hot melt coating.
