At present, the extraction method of the tea plant flower essential oil on the market mainly comprises a petroleum solvent extraction method, a supercritical carbon dioxide extraction and simultaneous distillation method and the like.
on the other hand, the invention patent with Chinese patent publication No. CN10349783A, tea flower essential oil, its preparation method and its application in cigarette, is that tea flower is used as raw material, and reduced pressure steam distillation method is adopted. Comprises the steps of soaking tea flowers in water or warm water in a sealing manner, then carrying out reduced pressure steam distillation, then extracting with a polar solvent to obtain a concentrate, finally backwashing the concentrate with ethanol to remove the residual polar solvent, and carrying out reduced pressure concentration to obtain the tea flower essential oil. However, this method employs a reduced pressure distillation method. In the preparation and extraction process, the loss of aroma components exists, and the volatile components in the tea flowers are difficult to keep. And the extraction process is relatively more complex. The corresponding manufacturing costs are higher.
the invention content is as follows:
