Problems solved by technology

In current research and production, vetiver oil is mainly prepared by traditional distillation and ethanol extraction. The main disadvantage of these two methods is that the yield of vetiver oil is low
At the same time, although vetiver oil has been widely used in food and spices, the method of applying vetiver oil to cigarettes to improve the quality of cigarette smoking has not been reported

Embodiment 1

[0027] The dry root of vetiver was crushed and passed through a 20-mesh sieve, and 200 g of the sieved dry root powder of vetiver was weighed and placed in an extraction container, 3000 mL of ethyl acetate was added, and the temperature was 50 ° C, the power was 1000 W, Ultrasonic extraction was carried out for 60 min at an empty ratio of 80%, repeated 4 times, filtered, combined extracts, the filtrate was distilled under reduced pressure, concentrated to a volume of 200 mL, and ethyl acetate was recovered at the same time. Add 1000 mL of ethanol with a concentration of 95% to the concentrated concentrated solution, stir while adding ethanol, the stirring speed is 600 rpm, and the time for adding ethanol is 10 min. The concentrated solution after adding ethanol was heated at 60° C. for 3 h, the extract was frozen at 4° C. for 24 h, filtered and concentrated to dryness to obtain 15.3 g of vetiver oil.

Embodiment 2

[0029] After crushing the dried vetiver root, pass it through a 60-mesh sieve, weigh 200g of the sieved dried vetiver root powder and place it in an extraction container, add 2000mL of acetone, and set the temperature at 20°C, with a power of 400W and a duty cycle Under the condition of 60% ultrasonic extraction for 20min, repeat 3 times, filter, combine the extracts, distill the filtrate under reduced pressure, concentrate to a volume of 100mL, and recover acetone at the same time. Add 300mL of ethanol with a concentration of 98% to the concentrated concentrated solution, stir while adding ethanol, the stirring speed is 300rpm, and the time for adding ethanol is 5min. The concentrated solution after adding ethanol was heated at 30° C. for 1 h, the extract was frozen at 1° C. for 6 h, filtered with suction and concentrated to dryness to obtain 13.2 g of vetiver oil.

Embodiment 3

[0031] The dry root of vetiver was crushed and passed through a 20-mesh sieve, and 200g of the sieved dry root powder of vetiver was weighed and placed in an extraction container, 2000mL of petroleum ether was added, and the Under the condition of 80% ultrasonic extraction for 40min, repeat 5 times, filter, combine the extracts, distill the filtrate under reduced pressure, concentrate to a volume of 100mL, and recover petroleum ether at the same time. Add 400mL of ethanol with a concentration of 98% to the concentrated concentrated solution, stir while adding ethanol, the stirring speed is 1000rpm, and the time for adding ethanol is 10min. The concentrated solution after adding ethanol was heated at 80° C. for 3 h, the extract was frozen at 1° C. for 12 h, filtered with suction and concentrated to dryness to obtain 18.5 g of vetiver oil.

Abstract

The invention discloses a preparation method of vetiveria zizanioides L. oil and an application of the vetiveria zizanioides L. oil in cigarettes. Vetiver roots are taken as raw materials and are subjected to smashing, organic solvent ultrasonic extraction, ethanol extraction and concentration to obtain the vetiver oil which is a specific spice for cigarettes. After being added to flue-cured tobacco type or mixed type cigarette tobaccos which are subjected to sensory evaluation, the specific spice for cigarettes has an important function of promoting the cigarette quality. The method disclosed by the invention is simple and convenient in process, simple in equipment, low in cost, slight in pollution and high in extraction rate; the component analysis shows that the total content of aroma components of a product is high, and the variety of the aroma components is rich.

Description

technical field [0001] The invention belongs to the technical field of cigarette additives, and in particular relates to a preparation method of vetiver oil, and at the same time, the invention also relates to the application of the vetiver oil in cigarettes. Background technique [0002] With the rapid development of science and technology and the change of people's habit of smoking cigarettes, more and more cigarette companies add various non-toxic natural product extracts to tobacco, so as to improve the quality and taste of cigarettes. [0003] Vetiver (Vetiveriazizanioides L), also known as Vetiver, is a perennial herb of the Gramineae family. Originally produced in India and other countries, it is mainly distributed in (sub)tropical regions such as Southeast Asia, India, and Africa. It has the characteristics of strong adaptability, fast production and reproduction, developed root system, drought and barren resistance, and has the characteristics of "the longest root s...
