Description
Technical field
The present invention relates to tangerine oil, especially relate to the device and method that a kind of overcritical chromatographic separation concentrates oxygenatedchemicals in the tangerine oil.
Background technology
Tangerine oil is the big class of one in the natural essence spices, mainly as the spices of products such as food, daily use chemicals, medicine, chemical industry, also is the main raw material of synthetic some spices.Tangerine oil mainly is present in pericarp, flower and the leaf of citrus, but with content in the pericarp the abundantest (1~3wt%).Mainly contain terpene compound (60~94%), oxygenatedchemicals (5~40%), wax ester and pigment (about 2%) four constituents in the tangerine oil, wherein oxygenatedchemicals is mainly compositions such as higher alcohols, aldehydes, ketone, ester class, be the main source of tangerine oil fragrance, it mainly represents composition is phantol; And terpene compound is mainly the unsaturated hydrocarbons constituents, and is very little to the contribution of fragrance, and is heated and the easy oxygenolysis of illumination, influences stability and the fragrance local flavor of product, and it mainly represents composition is limonene; Though wax ester and pigment composition content are seldom, being heated very easily produces the phototoxicity material with illumination, causes that essential oil is rotten and influences its quality product.Therefore, the tangerine oil spice product need remove terpene compound, wax ester and pigment composition.
Traditionally, main employing distillation method removes terpene compound (being mainly limonene) with solvent-extraction process and makes the oxygenatedchemicals (being mainly phantol) in the tangerine oil obtain separating concentrated, but these traditional method ubiquity separation and purification degree are not high, be difficult to remove wax ester and pigment composition, the extraction time is long, product is rotten under the high temperature, problems such as dissolvent residual and contaminate environment.At present, domestic and international research person adopts supercritical CO
