The invention discloses a
theaflavin enteric microcapsule particle, a preparation method and an application thereof. The preparation method comprises the following steps of: (1) dissolving 2-8 parts by weight of a
capsule material, which is an enteric material, into a 80%-95%
ethanol water solution to prepare 1%-8%
capsule material solution, dissolving 0.5-2 parts by weight of
theaflavin-containing tea extract into
distilled water to obtain 0.15%-2% core material solution, adding 2%-5% of
stearic acid into the core material solution, and stirring and emulsifying to obtain a core material
emulsion; and (2) mixing the
capsule material solution and the core material
emulsion, uniformly stirring, adding 0.01-0.1 part by weight of an antisticking agent and 1-8 parts by weight of
castor oil and / or span-80 into a mixture, stirring and emulsifying to obtain an
emulsion, and
drying the emulsion, wherein the weight ratio of the core material to the capsule material is 1:2 to 1:8. A
theaflavin enteric microcapsule disclosed by the invention is simple in preparation method and process, good in stability, convenient to store and transport, uniform in
granularity, good in dispersibility, high in medicament encapsulation rate and dissolubility and capable of being widely applied to the fields, such as health-care products, medicaments and the like.
