Embodiment 1

[0021] The preparation of fermented buku leaf essential oil for tobacco comprises the following steps:

[0022] (1) Preparation of fermented liquid: pulverize Buku leaves into 100-mesh Buku leaf meal, then place Buku leaf meal, glucose and water in a fermenter at a weight ratio of 15:1:84, and control the fermentation tank The pH value of the medium material is 4.5, the stirring speed is adjusted to 250rpm, and the ventilation rate is 1VVM. First, ferment at 5°C for 7 days, and then continue to ferment at 15°C for 7 days to obtain the fermentation liquid;

[0023] (2) Preparation of fermented bucur leaf essential oil for tobacco: use a volatile oil extractor to extract the fermented liquid obtained in step (1), then separate and extract the fermented liquid in an oil-water separator, collect the obtained oil layer, and obtain the fermented type Essential Oil of Buchu Leaf for Tobacco.

Embodiment 2

[0025] The preparation of fermented buku leaf essential oil for tobacco comprises the following steps:

[0026] (1) Preparation of fermented liquid: pulverize Buku leaves into 100-mesh Buku leaf meal, then place Buku leaf meal, glucose and water in a fermenter at a weight ratio of 15:1:84, and control the fermentation tank The pH value of the medium material is 5, the stirring speed is adjusted to 200rpm, the ventilation rate is 2VVM, and the fermentation is carried out at 8°C for 7 days, and then at 25°C for 5 days to obtain the fermentation liquid;

[0027] (2) Preparation of fermented bucur leaf essential oil for tobacco: use a volatile oil extractor to extract the fermented liquid obtained in step (1), then separate and extract the fermented liquid in an oil-water separator, collect the obtained oil layer, and obtain the fermented type Essential Oil of Buchu Leaf for Tobacco.

Embodiment 3

[0029] The preparation of fermented buku leaf essential oil for tobacco comprises the following steps:

[0030] (1) Preparation of fermented liquid: Pulverize Buku leaves into 120-mesh Buku leaves meal, then place Buku leaves meal, glucose and water in a fermenter at a weight ratio of 17:2:81, and control the fermentation tank The pH value of the medium material is 6, the stirring speed is adjusted to 180rpm, and the ventilation rate is 3VVM. First, ferment at 10°C for 5 days, and then continue to ferment at 25°C for 5 days to obtain a fermentation broth;

[0031] (2) Preparation of fermented bucur leaf essential oil for tobacco: use a volatile oil extractor to extract the fermented liquid obtained in step (1), then separate and extract the fermented liquid in an oil-water separator, collect the obtained oil layer, and obtain the fermented type Essential Oil of Buchu Leaf for Tobacco.

Abstract

The invention discloses a preparation method of fermentation-type buchu leaf essential oil for cigarettes. The method comprises the following steps: (1) preparation of fermentation liquid, wherein buchu leaves are ground into coarse buchu leaf powder, and fermenting the coarse buchu leaf powder, glucose and water at a weight ratio of (15-30):(1-5):(69-85) to obtain the fermentation liquid; (2) preparation of the fermentation-type buchu leaf essential oil for the cigarettes, wherein the fermentation liquid obtained in the step (1) is extracted and separated, and an obtained oil layer is collected to obtain the fermentation-type buchu leaf essential oil for the cigarettes. The preparation process is simple, the condition is mild, and the yield is high; moreover, an aromatic effect of small molecular substances generated by fermentation enables the fermentation-type buchu leaf essential oil for the cigarettes to have rich cigarette aromas and an effect of improving aroma and texture.

Description

technical field [0001] The invention relates to a preparation method of bucur leaf essential oil, in particular to a preparation method of fermented bucur leaf essential oil for tobacco. Background technique [0002] Microbial fermentation is an important part of biotechnology. It organically combines the basic principles of microbiology, biochemistry and chemical engineering. It is an engineering technology that uses the growth and metabolism of microorganisms to produce various useful substances. At present, the most widely used biotechnology in the biosynthesis of flavors and fragrances is microbial fermentation engineering. Using industrial and agricultural waste as raw materials, various natural flavors can be produced by using microorganisms. Flavor compounds produced by microbial fermentation mainly fall into four categories: terpenes, lactones, pyrans, and esters. Drawert and BantoS reported that citronellol, linalool and geraniol were isolated from Kluyveromyces la...
