The invention aims to provide a preparation method and application of biologically-fermented Chinese
angelica root oil. The preparation method comprises the following steps: performing
superfine grinding on Chinese
angelica root at a low temperature; performing wall breaking under increased pressure; adding a composite biological preparation for performing composite
hydrolysis and
fermentation; extracting fermented Chinese
angelica root volatile oil A by means of
water vapor distillation; performing suction
filtration; adding filter residue into
ethyl acetate, and heating and pressurizing to perform circular extraction of the Chinese angelica root oil; performing suction
filtration and concentration, and removing a
solvent to obtain Chinese angelica root oil B; compounding the Chinese angelica root oil A and the Chinese angelica root oil B to obtain the biologically-fermented Chinese angelica root oil. The biologically-fermented Chinese angelica root oil has the advantages of naturallycompounding natural smell such as the medicinal smell and of the Chinese angelica root and fresh fruit smell, lowering
irritation and improving the fragrance quality, along with higher free radial
scavenging capability and high
oxidation resistance. When the biologically-fermented Chinese angelica root oil is applied to cigarettes, the biologically-fermented Chinese angelica root oil has abundantand natural fragrance, medicinal smell, fresh smell, fruit smell and
fermentation smell, is coordinated with
smoke, makes the
smoke smell become clear, has the effects of resisting
inflammation, relieving pain and
asthma, improving laryngeal comfort degree, and overcomes the defects of over-strong medicinal smell, higher
irritation and presence of offensive
odor in the Chinese angelica root.
