Abstract
This invention discloses a method for extracting anise oil. The process for acquiring the anise oil comprises: 1) grinding the aniseed and sieving, mixing with water at the proportion of 1:5-30 and putting into the sample vials in the distillation and extraction tower, 2}adding ethyl ether to the solvent bottle in the distillation and extraction tower at the concentration of 2-20ml per gram of aniseed, heated at 40-70deg C for distillation and extraction. This method is characterized in that, by using the simultaneous distillation and extraction device, it combines the two steps of distillation and extraction to one step, and through multiple and large-area contact between water vapor and organic solvent in a relatively-closed container, the extraction of anise oil can be accomplished at one time. By taking this method, only small amount of organic solvent is needed to fulfill the extraction of anise oil with high efficiency, and the product contains little remaining organic solvent. This invention has the beneficial effects of simple procedures and easy operation, and is convenient for extensive spreading and application.
Description
Technical field
The present invention relates to a kind of method of extracting cumin oil.
Background technology
At present, that is that all right is ripe for the technology of extracting about cumin oil, the extraction of cumin oil is still based on traditional steam distillation, the principle of work of steam distillation extraction method is: each component dividing potential drop at a certain temperature equals the vapour pressure of the pure compound under same temperature in the mixture of immiscible volatile matter, and does not depend on the molar fraction of each component in the mixture.Therefore, in the mixed system of water vapor and sulfide, promptly boiling temperature is lower than the normal boiling point of water.In the phlegma of steam distillation the ratio of each component by the molecular weight of each compound and under this distillation temperature the vapour pressure of each component decide.
The supercritical fluid extraction method is to extract an important research direction of cumin oil method, but because the testing expenses height of supercritical fluid extraction method, complicated operation, influence factor is difficult to control, up to the present, adopt the supercritical fluid extraction cumin oil also not find stable, an ideal optimal processing parameter combination.The developing direction of cumin oil extractive technique is to seek a real extracting method fast and efficiently now, and can be used for large-scale industrial production.
Summary of the invention
The object of the invention provides the method for a kind of extraction efficiency height, extraction cumin oil that organic solvent residual is little.
Method provided by the present invention comprises the steps:
1) the fennel crushing screening of will resting in peace adds water and mixes in the sample bottle that is placed in the distilling and extracting device simultaneously, and the ratio of weight and number of rest in peace fennel and water is 1: 5-30;
2) add ether in the solvent bottle of distillation extraction tower at the same time, the rest in peace ether consumption of fennel of every gram is 2-20ml; Heat distillation extraction down at 40-70 ℃, obtain cumin oil.
Wherein, the order number that sieves of step 1) is preferably the 30-80 order; Step 2) time of distillation extraction is 0.5-5.0 hour.
The present invention extracts the method for cumin oil, be to utilize distilling and extracting device simultaneously, to distill and extract two steps is integrated, realize distillation and extract carrying out simultaneously, in airtight relatively container by water vapor mutually and the organic solvent phase repeatedly, the large-area contact, realize extraction once to cumin oil.Take the inventive method, use a spot of organic solvent just can finish extraction to cumin oil, extraction efficiency height; Remaining organic solvent content is little in the cumin oil that extraction obtains, and is lower than people's degree of having a sharp sense of smell basically; The inventive method step is simple, and is easy to operate, is convenient to large-scale promotion application.
