Abstract

The invention discloses a method for extracting anise seed oil. The method comprises the following preparation steps of smashing anise seeds subjected to impurity removing, cleaning and drying to obtain anise seed powder; adding Vitamin E into the anise seed powder and putting the mixture into a magnetic field to be processed; feeding the anise seed powder subjected to magnetization processing into an extraction kettle to perform supercritical CO2 extraction to obtain crude oil; performing vacuum drying on the crude oil to obtain the anise seed oil. According to the method for extracting the anise seed oil, the magnetic field extraction technology, the supercritical CO2 extraction technology and the vacuum drying technology are combined, extraction pressure and temperature of supercritical CO2 extraction are reduced, extraction time is shortened, and extraction efficiency is increased. In addition, the obtained anise seed oil is high in purity and less in moisture, and preservation time of the anise seed oil is prolonged. Therefore, the method can extract the anise seed oil safely and efficiently.

Description

technical field [0001] The invention relates to the technical field of vegetable oil extraction, in particular to a method for extracting star anise seed oil. Background technique [0002] Star anise, also known as star anise, scientific name Illicium verum, belongs to Magnoliaceae, is a special aromatic plant in my country. The fruit of star anise can be used as medicine. It is warm in nature and pungent in taste. It has the effects of warming yang and expelling cold, regulating qi and relieving pain. Star anise seed oil is obtained by steam distillation from mature fruit kernels of star anise. It is a colorless to pale yellow clear liquid with a fragrant gas and a pungent and sweet taste. Star anise seed oil is an excellent food seasoning that people like to use. It has the effect of warming the heart and invigorating the stomach. It can stimulate the nerves and blood vessels of the gastrointestinal tract, promote the secretion of digestive juice, increase gastrointestina...
