Embodiment 1

[0045] Add 100kg of green tea leaves and 250kg of water into the extraction pot, extract and reflux under reduced pressure at a temperature of 90°C and a vacuum of 0.02Mpa for 8 hours. Then the mixture in the leaching pot was cooled to room temperature, filtered out the filter residue with gauze and collected to obtain 200 kg of filtrate, which was used as the first extract, in the form of a dark green liquid.

[0046] Put the filter residue into the original extraction pot, then add 125kg of water, extract and reflux under reduced pressure at a temperature of 90°C and a vacuum of 0.02Mpa for 6 hours, filter the filter residue with gauze again and collect the filtrate to obtain the second extract 100kg , in the form of dark green liquid.

[0047] Put the filter residue back into the original extraction pot again, add 100kg of water, extract and reflux under reduced pressure for 5 hours under the same conditions, filter the filter residue with gauze and collect the filtrate to ...

Embodiment 2

[0051] Add 100 kg of Chrysanthemum chrysanthemum (flowers) in the extraction pot, mass concentration is 95% alcohol 250 kg, and the temperature is 90° C., and the vacuum degree is 0.025 Mpa to extract and reflux under reduced pressure for 7 hours. Then the mixture in the leaching pot was cooled to room temperature, and the filter residue was filtered out with gauze and collected to obtain 200 kg of filtrate, which was brownish-yellow liquid.

[0052] Add the obtained first extract to a concentration pot for concentration, the steam pressure is 0.015Mpa, the temperature is 85°C, and 180kg of alcohol is recovered as the solvent for the second extraction.

[0053] Put the filter residue into the leaching pot, then add 180kg of recovered alcohol, extract and reflux under reduced pressure at a temperature of 80°C and a vacuum of 0.025Mpa for 4 hours, filter the filter residue with gauze again and collect the filtrate to obtain the second extract 150kg, in the form of brown-yellow l...

Embodiment 3

[0058] Add 100kg of menthol and 200kg of alcohol with a mass concentration of 90% in the extraction pot, extract and reflux under reduced pressure at a temperature of 50°C and a vacuum of 0.02Mpa for 7 hours. Then the mixture in the extraction pot was cooled to room temperature, the filter residue was filtered out with gauze, and 150 kg of filtrate was collected, which was used as the first extract.

[0059] Add the obtained first extract to a concentration pot for concentration, the concentration steam pressure is 0.015Mpa, the temperature is 85°C, and 125kg of alcohol is recovered as a solvent for the second extraction.

[0060] Put the filter residue into the leaching pot again, add 125kg of recovered alcohol, extract and reflux under reduced pressure at a temperature of 80°C and a vacuum of 0.025Mpa for 6 hours, filter the filter residue with gauze again and collect the filtrate to obtain 100kg of the second extract .

[0061] Add the obtained second extraction liquid int...

Abstract

The invention relates to a preparation method of a tobacco extract and a product obtained by using the method. The preparation method comprises the steps of low-temperature vacuum extraction, stirring and vacuum concentration and allows the circulation use of a solvent, so that the method is characterized by safety, environmental protection, high extraction efficiency, low production cost, high product yield and the like, can be simultaneously applicable to extracting a variety of types of tobacco extracts and can produce the high-quality tobacco extract. The extract product obtained by the preparation method has the beneficial effects of instant solubility and good dispersibility and is easy to add in tobacco essence and tobacco casing.

Description

【Technical field】 [0001] The invention relates to the technical field of flavoring essence for tobacco, more specifically, the invention relates to a method for preparing tobacco extract with relatively high yield and recovery rate, and a product obtained by the method. 【Background technique】 [0002] In the past ten years, some domestic spice manufacturers and research institutes have successively carried out the research and production of tobacco extract, and successively developed natural tobacco flavors such as Burley tobacco extract, Yunyan extract and sun-cured red tobacco extract. [0003] Tobacco extract is a tobacco flavor commonly used in cigarette products, which can enhance the characteristic cigarette aroma of cigarette products. However, the existing tobacco extracts in the domestic market contain a small amount of macromolecular substances such as cellulose, hemicellulose, and pectin. The existence of these substances will affect the aroma quality of cigarette...
