Abstract
The invention relates to a method for extracting citrus peel oil, which is characterized in that citrus peel is squeezed, stirred, precipitated, separated and fractionated to prepare high-grade pure citrus peel spice essential oil, and the effective component of limonene can reach 95%.
Description
An extraction method of citrus peel oil belongs to the technical field of fine chemical engineering.
The orange peel, including the peel of fruits such as orange, shaddock, orange and the like, contains high-grade perfume essential oil, and the natural components in the orange peel are widely used in the industries of chemical industry, medicine, food and the like. The domestic patent documents since 1985 were searched, the same reports on the extraction process or method of citrus peel oil are not found, and only one report entitled "method for extracting pectin from citrus peel and simultaneously preparing various useful products" with application number 85102662 is searched, wherein the method is mainly used for producing pectin, and the technology is that citrus peel is extracted with alcohol, and then distilled and concentrated to obtain citrus red pigment. Soaking the extracted pericarpium Citri Tangerinae with hydrochloric acid, extracting pectin with 90-95 deg.C hot water, and condensing the vapor to recover aromatic oil. In the prior art, no method for directly extracting citrus peel oil from citrus exists, and no technology for preparing the citrus peel oil by an extrusion mode exists.
The invention aims to extract citrus peel oil with pure natural components from citrus peel, and the process is easy to operate, low in production cost and pure in product.
A method for extracting mandarin orange peel oil comprises, transversely cutting and covering cleaned mandarin orange, removing pulp and peel to obtain kettle-shaped mandarin orange peel;
secondly, sheathing the kettle-shaped orange peel on a spherical extrusion ball, and directly squeezing the orange peel to obtain orange peel crude oil containing water;
and thirdly, placing the citrus peel crude oil into a stirring tank, stirring and precipitating, taking out the supernatant citrus peel oil, placing the citrus peel oil into a fractionating tower, and carrying out high vacuum fractionation at the temperature of 100 ℃ and 150 ℃ to obtain the pure citrus peel essential oil.
Compared with the prior art, the method can extract the oil juice from the citrus peel at one time, particularly obtain the citrus peel oil by directly squeezing the citrus peel, and prepare the essential oil by stirring, precipitation separation and vacuum fractionation, and has the advantages of simple operation and contribution to improving the purity of the product.
Detailed Description
The following detailed description is to be read in connection with specific embodiments, but it should be understood that the scope of the invention is not limited to the specific embodiments.
The embodiment of the invention is that the residue and pesticide ingredients in the peel of the orange are removed, the orange is cleaned by clean water, the cleaned orange is transversely cut and covered, the pulp is dug out and separated from the peel, and the kettle-shaped orange peel is obtained; sheathing the kettle-shaped orange peel on a spherical extrusion ball, and directly squeezing the orange peel to obtain orange peel crude oil containing water; and then the orange peel crude oil is put into a stirring tank, is stirred and then is precipitated, the supernatant orange peel oil is taken out, and the orange peel oil is put into a fractionating tower and is subjected to high vacuum fractionation at the temperature of 100-150 ℃ to obtain the pure orange peel essential oil. After the citrus peel oil and water are squeezed out, the peel residue is changed into dry powder, and can be used as a raw material in the industries of fertilizer, feed, building materials and the like.
The method for extracting the citrus peel oil can also be used for processing peels of pomelos, oranges and the like to extract essence oil, and has the advantages of high effective ingredients of products, small equipment investment and simple operation.
Claims (1)
