Abstract

The invention discloses a method for extracting rose essential oil from a bitter rose and series products thereof, which comprises the steps as follows: a. extracting a rose extract: a1. the rose is put into a stainless steel pressure container; a2. environment protective Freon (R134a, R23) is injected into an extraction tank and the ratio of the material to a solvent is 1.0:1.3 to 1.5; a3. the extraction time is 2 to 5 and each time takes 1.0 to 1.5 hours; the temperature is 15 to 35 DEG C and the pressure is 0.15 to 0.75 MPa for obtaining the rose extraction liquid; and a4. the rose extraction liquid is added into a vaporizing tank, and decompress-vaporized for 80 to 110min under the pressure of 0.15 to 10Pa and the temperature of 30 to 50 DEG C, thus obtaining the rose extract; and b. extracting the rose essential oil and the rose neat oil; b1. the rose extract is dissolved into 1 to 4 times of 95 percent ethanol, arranged into the large tube of a tubular centrifuger, and then arranged in a high speed freezing centrifuger for obtaining rose wax and a rose centrifugal liquid; b2. the rose centrifugal liquid is condensed in vacuum for recycling the ethanol and obtaining the rose coarse oil; and b3. the rose coarse oil is finely stern by a rotary vaporizing/depressurizing fractionating instrument; and the rose net oil is left in a round flask.

Description

technical field [0001] The invention relates to a method for extracting essential oil, in particular to a method for extracting rose essential oil and series products from Kushui rose. Background technique [0002] Kushui rose is one of the four major rose strains in my country, which has high economic, ecological and ornamental value. For a long time, the production of rose oil mainly adopts indigenous equipment and steam distillation. The former is to put roses into the essential oil extraction tank, add tap water 3 to 4 times the weight of roses, cover the material inlet cover, tighten the screws to seal, and then heat the lower part of the extraction tank with coal or electric heating. Without a stirring device, the heating is very uneven, so that the aroma of rose oil is greatly lost, accompanied by an unpleasant smell, and there are many impurities in the oil, the color is cloudy, easy to oxidize and change the taste, and the characteristic aroma of rose oil is lost. ...
