Abstract
The invention relates to an edible essence and particularly relates to a sweet orange peel essence and belongs to the field of food additives. The edible essence is a sweet orange peel essential oil. The edible essence is prepared by the steps of: carrying out microwave treatment on a raw material and then carrying out steam distillation to obtain an essential oil; and refining the sweet orange peel essential oil through the obtained essential oil by using supercritical CO2. The sweet orange peel essential oil prepared by the method has high purity and strong sweet orange taste.
Description
Technical field
The present invention relates to a kind of food flavour, belong to foodstuff additive field.
Background technology
Sweet orange peel, refers to the pericarp of a class sweet orange plant to have clearing heat and detoxicating, the dry effect of relieving inflammation or internal heat, dispel, its essential oil is the combination that contains the compound with strong aromatic odour, contain a large amount of terpenoid substances, can be used as a kind of spices that uses, for the processing of the numerous food such as beverage.
The process for purification of spices is mainly by steam distillation, supercritical extraction and organic solvent extractionprocess.
Steam distillation is by utilizing high-temperature water vapor to make the spices of the oily method of separating with water vapor of vaporizing, isolated steam is carried out carrying out oily water separation after condensation, obtaining essential oil.The extraneous solvent contamination of the method, can obtain the essential oil product that purity is higher, but its rate of recovery is lower.Provide the yield of essential oil though be widely used at present the extraction liquid after essential oil refluxes by extraction method, but essential oil in these extraction liquids only circulates in system, and be the effective yield of raising essential oil.
Thereby organic solvent extractionprocess is to utilize spices different solubility in different organic solvents to select suitable organic solvent that spices is separated, conventional solvent is ethanol etc., but it is evident that, in the process of Separation of Organic and essential oil, tend to residual a small amount of solvent in essential oil, cause essential oil pollution in various degree.
Supercritical extraction is to utilize temperature, pressure to carry out the extraction of spices as solvent higher than the fluid of stagnation point.Because supercutical fluid had both had mobility and the solvability of fluid, there is again the good diffustivity of gas simultaneously.In the time there is comparatively faint variation in ambient conditions, can cause the noticeable change of supercutical fluid, the extraction that utilizes supercutical fluid to carry out spices can obtain the high and free of contamination spices essential oil of purity, and conventional supercutical fluid is supercritical CO
2.But supercritical extraction price is comparatively expensive.
