Embodiment 1

[0033] After cleaning the discarded tobacco seeds, dry them at a temperature not higher than 50°C, and then crush them with a high-speed pulverizer; weigh 20g of the crushed tobacco seeds powder and pass through a 20-40 mesh sieve, and evenly fill it into the extraction kettle. Set extraction pressure to 18MPa, extraction temperature to 35°C, CO 2 The flow rate is 5L / h, and the output valve temperature is set at 100°C. Static extraction was carried out for 1 hour first, followed by dynamic extraction for 0.5 hour. After the extraction was completed, the extract was collected to obtain 0.42 g of tobacco seed volatile oil.

Embodiment 2

[0035] After cleaning the waste tobacco seeds, dry them at a temperature not higher than 50°C, and then pulverize them with a high-speed pulverizer; weigh 20g of tobacco seeds powder that has been pulverized and passed through a 40-60 mesh sieve, and evenly fill it into the extraction kettle. Set the extraction pressure to 21MPa, the extraction temperature to 40°C, CO 2 The flow rate is 7L / h, and the output valve temperature is set at 100°C. Static extraction was carried out for 1 hour first, and then dynamic extraction was performed for 1 hour. After the extraction was completed, the extract was collected to obtain 0.46 g of tobacco seed volatile oil.

Embodiment 3

[0037] After cleaning the waste tobacco seeds, dry them at a temperature not higher than 50°C, and then pulverize them with a high-speed pulverizer; weigh 20g of tobacco seeds powder that has been pulverized and passed through a 40-60 mesh sieve, and evenly fill it into the extraction kettle. Set the extraction pressure to 25MPa, the extraction temperature to 45°C, CO 2 The flow rate is 7L / h, and the output valve temperature is set at 100°C. Static extraction was performed for 1.5 hours first, and then dynamic extraction was performed for 1.5 hours. After the extraction was completed, the extract was collected to obtain 0.52 g of tobacco seed volatile oil.

Abstract

The invention discloses volatile oil extracted from waste tobacco seeds of aromatic tobacco, as well as a preparation method and application of the volatile oil. The preparation method comprises the following steps: firstly, washing and drying waste tobacco seeds, smashing the washed and dried waste tobacco seeds with a high-speed pulverizer, and sieving the powder for standby application; then, uniformly filling a supercritical extraction device with the sieved tobacco seed powder, setting the extraction pressure, temperature and CO2 flow, and setting the temperature of an output valve to be 100 DEG C; performing static extraction and dynamic extraction sequentially, and after the extraction, collecting extract liquor to obtain the volatile oil. According to the preparation method, the extraction condition is mild, the extraction efficiency is high, the operation is simple, the industrial production is facilitated, and the extracted volatile oil can be applicable to perfuming of cigarettes.

Description

technical field [0001] The present invention relates to a volatile oil extracted from oriental tobacco waste tobacco seeds and its preparation method and application, in particular to a volatile oil extracted from oriental tobacco waste tobacco seeds by supercritical carbon dioxide extraction technology and its preparation method and application. Background technique [0002] Tobacco is a plant of the genus Nicotiana in the family Solanaceae, and is a natural plant with high utilization value. As a traditional Chinese medicine, tobacco was first recorded in "Jingyue Quanshu", and it is also included in modern Chinese herbal medicine monographs such as "National Chinese Herbal Medicine Compilation". It has the effects of reducing swelling, detoxifying, and killing insects. [0003] In the past 400 years, tobacco has been widely cultivated as an important economic crop. my country's tobacco planting area and output rank first in the world, and tobacco planting and product pro...
