The invention provides a preparation method and application of
green tea essence for cigarette dropping pills. The preparation method of the
green tea essence comprises the steps that a
green tea aroma component in green tea is extracted through
supercritical fluid,
olive oil is added to so as to fully dissolve the green tea
aroma component, and after filtering, a first component is obtained; an
ethanol solution and
citric acid are added to the green tea obtained after
supercritical fluid extraction for
reflux extraction twice, filter liquors are combined, decompressing concentration is conducted, and then a second component 2 is obtained; Span80 is added to the first component, so that a phase A is obtained; the second component, water,
glycerol, Tween80 and carbomer are evenly stirred, so that a phase B is obtained; the phase A and the phase B are heated respectively, the phase A is slowly added to the phase B for homogenization, after the pH value is added, a
vitamin C
aqueous solution is added, and then the green tea essence for the cigarette dropping pills is obtained. The prepared green tea fragrance is of an oil-in-water
system, the
active component, tea
polyphenol, of the green tea is added to the water phase, and the potential toxic and side effects of a compound are avoided; and no off-
odor exists, and when applied to
cigarette filter tips, the green tea essence has the anti-oxidation function and can remove free radicals in
smoke.
