Process of preparing burdock composite micron essence

摘要

A process of preparing a burdock composite micron essence at least includes the following. Dissolved and heated phospholipid is added to a vegetable oil extract and then stirred. After stirring, the above mixture is pour into a heated glycerol and then further stirred and a burdock extract aqueous solution is added. The aforementioned mixed solution is stirred at high speed, the emulsion-homogenized solution is subject to high-pressure homogenization, and a filtration membrane is used to filter the homogenized solution obtained to get a purple transparent burdock concentrate. The burdock concentrate is used to prepare the formulation of nano-micro emulsion which is easily absorbed by human body and thus grants improved health benefits.
