Embodiment 1

[0030] A method for extracting jasmine essential oil and head fragrance, comprising the following process steps:

[0031] (1) Distillation: Put 100kg of fresh jasmine evenly into 2 steaming baskets, then put them into the distillation tanks respectively, cover the distillation tank lids with steaming conduits, and distill with water steam under the vacuum degree of -0.07Mpa To obtain mixed steam, the temperature should be controlled at 70°C and the distillation time should be 2.5h during the distillation process;

[0032] (2) Condensation: the mixed steam obtained by distillation is condensed by the condenser, and the oil-water mixture is obtained after condensation;

[0033] (3) Oil-water separation: After the oil-water mixture obtained above is subjected to oil-water separation, jasmine essential oil and pure dew are obtained;

[0034] (4) Adsorption: Under the vacuum degree of -0.07Mpa, the jasmine head fragrance is transported to the adsorber, and 30g of activated carbon ...

Embodiment 2

[0040] A method for extracting jasmine essential oil and head fragrance, comprising the following process steps:

[0041] (1) Distillation: Put 100kg of fresh jasmine evenly into 3 steaming baskets, then put them into the distillation tanks respectively, cover the distillation tank lids with steaming conduits, and distill with water steam under the vacuum degree of -0.08Mpa To obtain mixed steam, the temperature should be controlled at 75°C during the distillation process, and the distillation time should be 2h;

[0042] (2) Condensation: the mixed steam obtained by distillation is condensed by the condenser, and the oil-water mixture is obtained after condensation;

[0043] (3) Oil-water separation: After the oil-water mixture obtained above is subjected to oil-water separation, jasmine essential oil and pure dew are obtained;

[0044] (4) Adsorption: Under the vacuum degree of -0.08Mpa, the jasmine head fragrance is transported to the adsorber, and 35g of activated carbon i...

Embodiment 3

[0050] A method for extracting jasmine essential oil and head fragrance, comprising the following process steps:

[0051] (1) Distillation: Put 100kg of fresh jasmine evenly into 4 steaming baskets, then put them into the distillation tanks respectively, cover the distillation tank lids with steaming conduits, and distill with water steam under the vacuum degree of -0.09Mpa To obtain mixed steam, the temperature should be controlled at 80°C and the distillation time should be 1.0h during the distillation process;

[0052] (2) Condensation: the mixed steam obtained by distillation is condensed by the condenser, and the oil-water mixture is obtained after condensation;

Abstract

The invention discloses a method for extracting essential oil and headspace volatile of arabian jasmine flowers. The method comprises the steps of distilling, condensing, oil water separating, adsorbing, primary rectifying concentrating, alcohol precipitating, secondary rectifying concentrating and the like. According to the method, in a vacuum state, vapor is adopted to distill the essential oil of the arabian jasmine flowers, distilling temperature is reduced, distilling time is shortened, the use rate of equipment is improved, the quality and yield of the essential oil of a product are improved, the production cost is reduced, and the technical problems of the existing traditional solvent method and supercritical carbon dioxide method are overcome. The headspace volatile of the arabian jasmine flowers is obtained by concentrating of a rectifying tower, and compared with the existing reduced pressure distillation, the method has the advantages that the loss of easy-to-volatile headspace volatile component is reduced, and the purity of the headspace volatile can be improved. By using the method in the invention to extract the essential oil and headspace volatile of the arabian jasmine flowers, the yields are respectively 0.23-0.28% and 5.5-6.0% and the yields of the respective components are obviously improved.

Description

technical field [0001] The invention relates to the technical field of extraction of aromatic essential oils, in particular to a method for extracting jasmine essential oil and top aroma. Background technique [0002] Essential oil is an oily substance with volatile aroma produced in aromatic plants, which can be obtained from flowers, leaves, branches, roots, bark, gums, whole grasses and fruits of aromatic plants. The main components of plant essential oils are generally alcohols, aldehydes, acids, phenols, acetones, terpenes and other compounds, which are widely used in pharmaceuticals, insecticides, bacteriostasis, food additives, and daily cosmetics. application. Among them, jasmine essential oil is the essential oil extracted from Jasminum sambac (L.) Ait, Oleaceae Jasmine. Jasmine essential oil is known as the "king of essential oils". It has an elegant scent, which can relieve depression, invigorate the spirit, and improve self-confidence. At the same time, it can ...
