Deacidification and deodorization method for tea oil

The invention discloses a deacidification and deodorization method for tea oil. According to the deacidification and deodorization method disclosed by the invention, a carbon dioxide fluid extraction technology is adopted for performing deacidification and deodorization treatment on crude oil of the tea oil, wherein carbon dioxide fluid comprises supercritical carbon dioxide fluid, subcritical carbon dioxide fluid and liquid carbon dioxide; and extraction ways comprise extraction and countercurrent extraction. The process disclosed by the invention is simple, environmental pollution caused by alkali refining and deacidification and damages to bioactive substances and nutritional components in traditional steam heating and deodorization can be avoided, and the quality and health-care function of finished product tea oil can be further improved.
