Embodiment 1

[0021] A kind of extracting method of jasmine essential oil, concrete steps are as follows:

[0022] 1) Material preparation: select jasmine flowers with a flowering time of 4 hours, pick them up, remove impurities, bake and dry them at a low temperature for 1.5 hours at a temperature of 20°C without oxygen, until the water content of the jasmine flowers is 30%, and then put the jasmine flowers into the broken In the wall-breaking machine, carry out wall-breaking and crushing for 2 minutes, and crush it into jasmine powder with a particle size of 400 mesh; in order to prevent the waste of flying dust of jasmine powder, spray a small amount of water spray when pouring out of the wall-breaking machine;

[0023] 2) Ultrasonic-enzyme-assisted extraction: Add water to the crushed jasmine powder to a ratio of solid to liquid of 1:3, and ultrasonically treat it for 15 minutes at a power of 200w and a frequency of 30Hz. Since heat will be generated during the ultrasonic process, this p...

Embodiment 2

[0026] The present embodiment is the same as Example 1, except that the baking temperature in step (1) in the present embodiment is 25° C., and the particle size of the jasmine powder is 500 mesh.

Embodiment 3

[0028] This example is the same as Example 2, except that the enzymatic hydrolysis time in step (2) in this example is 70 minutes, and the extraction temperature in step (3) is 120°C.

Abstract

The invention discloses an extraction method of jasmine flower essential oil and in particular relates to the technical field of essential oil extraction. The extraction method comprises the followingsteps: treating raw materials by adopting a cell wall breaking machine; then treating crushed jasmine flowers with the help of ultrasounds and enzymolysis; finally, extracting the essential oil fromthe pre-treated jasmine flowers by adopting a subcritical water extraction technology; carrying out centrifugal oil-water separation on an extracting solution and filtering a separated oil phase to prepare the finished-product jasmine flower essential oil. The extraction method disclosed by the invention has the advantages of low energy consumption and high extraction efficiency; the adopted extracting solution is water so that the extraction method is environmentally friendly and performance and structure of the essential oil are not changed.

Description

technical field [0001] The invention belongs to the technical field of flavors and fragrances, relates to the technical field of essential oil extraction, in particular to a method for extracting jasmine essential oil. Background technique [0002] Flavors and fragrances are the products of "high, refined and new" technologies that emerged with the development of modern industry. They have been widely used in food, daily chemical, tobacco and other industries, and are closely related to people's daily life. On this basis, a highly specialized and centralized flavor and fragrance industry has been formed. [0003] Jasmine is a typical "temperament flower". The aroma released by the jasmine flower is rich and elegant, fragrant and refreshing. It has health care effects such as relieving depression, invigorating the spirit, caring and improving the skin. It is widely used in jasmine tea processing, daily chemical industry, food, medical treatment and other fields. There are m...
