Abstract

The present invention relates to the process of extracting aniseed oil from aniseed. Aniseed is first crushed and then supercritical CO2 extracted at the pressure of 10-25MPa, temperature of 30-50 deg.c for 0.5-4 hr and CO2 flow rate of 0.5-2 kg/hr for each Kg aniseed material, and the extract is collected as the aniseed oil. The process of the present invention is stable, reliable, obvious in separating effect, high in product quality, less wastes produced and reuseability of CO2, and low in power consumption and water.

Description

technical field [0001] The invention relates to a chemical extraction method, in particular to a 2 The method of supercritical extraction is a method of extracting and separating fennel oil from star anise. Background technique [0002] Fennel oil, alias: anise oil, main components: trans-anethole (>80%), anisaldehyde, 1,8-cineole, p-allyl anisole (tarrone), methyl Terpineol, linalool, limonene, α-phellandrene, etc. Preparation method: from star anise (Illicium verum), dried star anise fruit is 8% to 12%. This product has the characteristic aroma and fragrance of clear and sweet spicy star anise. Strong sense of sweetness. Star anise is one of the traditional seasoning spices in our country. Its essential oils can be used in confectionery, beverages and alcohol flavors. For example, Sashi essence is composed of it, wintergreen and some other spices. It can also be used in candied fruit flavor together with other spices. The combination of star anise oil and sweet ...
