Embodiment 1

[0013] 10 kilograms of fresh carrots were shredded, dried in the air, dried at 50° C. until the water content was 3%, and pulverized to obtain 1.2 kilograms of carrot dry powder. Get 800g of carrot powder and pack it into a supercritical extraction tank, and add 100g of 95% edible alcohol to the carrot powder as an entrainer to carry out supercritical extraction of carbon dioxide. The pressure of the extraction tank is 15Mpa, the extraction temperature is 35°C, the pressure of the separation tank is 8Mpa, and the separation temperature is 60°C. After the product is no longer separated from the separation tank, the extraction is stopped to obtain 85 g of carrot supercritical extract.

[0014] Add 95% ethanol to the carrot supercritical extract obtained above to dilute to 1000ml, mix evenly and put it into a 2000ml three-neck flask, slowly add 20ml hydrogen peroxide dropwise, heat and reflux for 5 hours to obtain the oxidation product. Add 0.5 g of sodium borohydride to the oxi...

Embodiment 2

[0017] 10 kilograms of fresh carrots were shredded, dried in the air, dried at 50° C. until the water content was 3%, and pulverized to obtain 1.2 kilograms of carrot dry powder. Get 800g of carrot powder and pack it into a supercritical extraction tank, and add 150g of 95% edible alcohol to the carrot powder as an entrainer to carry out supercritical extraction of carbon dioxide. The pressure of the extraction tank is 25Mpa, the extraction temperature is 45°C, the pressure of the separation tank is 7Mpa, and the separation temperature is 60°C. After the product is no longer separated from the separation tank, the extraction is stopped to obtain 140 g of carrot supercritical extract.

[0018] Add 95% ethanol to the carrot supercritical extract obtained above to dilute to 1000ml, mix evenly and put it into a 2000ml three-necked flask, slowly add 20ml hydrogen peroxide dropwise, heat and reflux for 7 hours to obtain the oxidation product. Add 0.8 g of sodium borohydride to the ...

Embodiment 3

[0021] 10 kilograms of fresh carrots were shredded, dried in the air, dried at 50° C. until the water content was 3%, and pulverized to obtain 1.2 kilograms of carrot dry powder. Get 800g of carrot powder and pack it into a supercritical extraction tank, and add 200g of 95% edible alcohol to the carrot powder as an entrainer to carry out supercritical extraction of carbon dioxide. The pressure of the extraction tank is 30Mpa, the extraction temperature is 50°C, the pressure of the separation tank is 6Mpa, and the separation temperature is 60°C. After the product was no longer separated from the separation tank, the extraction was stopped to obtain 181 g of carrot supercritical extract.

[0022] Add 95% ethanol to the carrot supercritical extract obtained above to dilute to 1000ml, mix evenly, put it into a 2000ml three-necked flask, slowly add 20ml hydrogen peroxide dropwise, and heat to reflux for 7 hours to obtain the oxidation product. Add 1 g of sodium borohydride to the ...

Abstract

A liquid extract of carrot used for flavouring the cigarettes is prepared from carrot through pulverizing, loading the powdered carrot into extractor, adding alcohol, supercritical CO2 extracting, adding alcohol to the liquid extract, dripping H2O2, refluxing to obtain the oxidized product, adding sodium bromohydride, refluxing, cooling and filtering.

Description

technical field [0001] The invention relates to a supercritical carrot extract and its application in cigarette flavoring, and mainly relates to a carbon dioxide supercritical extraction and processing method of carrots. The carrot extract obtained by the method has a good effect in cigarette flavoring. application effect. technical background [0002] As the problems of smoking and health attract more and more attention, the development of low-tar and low-harm cigarettes is an inevitable development trend of cigarettes. Since the adoption of some measures to reduce tar and harm will inevitably cause the problem of insufficient cigarette flavor, we can make up for the cigarette aroma by adding some flavor substances to cigarettes. Tobacco contains a certain amount of carotene and carotenoids, which will undergo physiological degradation during the tobacco alcoholization process, and the degradation products will produce a large number of flavor compounds, which are importan...
