Embodiment

[0026] A method utilizing high-frequency ultrasonic cavitation technology to prepare jasmine extract, comprising the following steps:

[0027] A. Add the extraction solvent in the ultrasonic extraction tank, put the jasmine flower into the extraction solvent, make the solvent submerge the jasmine flower, and stir evenly;

[0028] B. During the stirring process, the ultrasonic generator is turned on intermittently, and the megahertz band ultrasonic wave is directly applied to the mixed liquid;

[0029] C. filtering the supernatant of the extract, and squeezing the raffinate, merging the filtrate and the squeezing liquid;

[0030] D. Extract the combined filtrate and squeezed liquid to obtain jasmine extract.

Abstract

The invention relates to a preparation method of jasmine concrete and discloses a method for preparing jasmine concrete by using a high-frequency ultrasonic cavitation technology. The method comprises the following steps: A, adding an extracting solvent into an ultrasonic extraction tank, placing arabian jasmine flowers in the extracting solvent which immerses the arabian jasmine flowers, and uniformly stirring; B, in the stirring process, intermittently starting an ultrasonic generator for carrying out direct ultrasonic effect in a megahertz band on the mixed liquid; C, filtering the supernate of the leach liquor, squeezing the residual liquid and mixing the filtrate and the pressed liquor; and D, extracting the mixed filtrate and pressed liquor to obtain the jasmine concrete. The method provided by the invention is applicable to extraction of jasmine concrete, and an effective cavitation effect is generated by using ultrasound in the megahertz band to break the cell walls of the plant, so that the extraction efficiency of effective components is greatly improved and the final quality of the jasmine concrete is further improved.

Description

technical field [0001] The invention relates to a preparation method of jasmine extract. Background technique [0002] Jasmine extract can be used in food flavors, such as strawberry, cherry, apricot, peach and other fruity flavors as a modifier, which can produce a round and harmonious effect. It can also be used in high-end perfumes, soaps and cosmetic essences. [0003] The existing jasmine extract preparation method comprises two processes of leaching and concentration. The leaching process uses a leaching tank, and a solvent distributor and filter with a special structure are installed inside the leaching tank. The flower is the stationary phase, the solvent is the mobile phase, and the solvent is petroleum ether. The operating conditions of leaching are: the first leaching solvent ratio is 2.5:1, 2 hours; the second leaching solvent ratio is 1.5:1, 30 minutes; the third leaching solvent ratio is 1.5:1, 30 minutes. The concentration process adopts a three-stage seri...
