Problems solved by technology

[0004] The existing extracts for Heibulin tobacco are mainly extracted with water or ethanol, and then the extract is made by enzymolysis and fermentation. Due to the long production cycle and high cost of enzymolysis and fermentation, the extract is expensive, which limits the Its application in ordinary cigarettes

Embodiment 1

[0022] A kind of preparation method of extract for black pulin tobacco, comprises the following steps:

[0023] (1) After washing the black bulin, add 3 times the weight of water, homogenize it with a high-speed homogenizer at 16000 rpm for 15 minutes, then carry out countercurrent ultrasonic extraction of the slurry, the ultrasonic frequency is 80KHz, and the ultrasonic power is 150W, the extraction time is 50min, and the extraction temperature is 40°C. After filtration, the extract and filter residue are collected, and the extract is concentrated under reduced pressure to 0.2 times the weight of the extract to obtain a water-extraction concentrate;

[0024] (2) add 8 times of weight 80% ethanol in filter residue, carry out homogenization with high-speed homogenizer again, then slurry is carried out countercurrent ultrasonic extraction, collect alcohol extract after filtering (the condition of high-speed homogenization and countercurrent ultrasonic extraction is the same as S...

Embodiment 2

[0028] A kind of preparation method of extract for black pulin tobacco, comprises the following steps:

[0029] (1) After the Heibulin is washed, add 2 times the weight of water, and use a high-speed homogenizer with a rotation speed of 10,000 rpm to homogenize for 20 minutes, and then carry out countercurrent ultrasonic extraction of the slurry, the ultrasonic frequency is 50KHz, and the ultrasonic power is 100W, the extraction time is 60min, and the extraction temperature is 60°C. After filtration, the extract and filter residue are collected, and the extract is concentrated under reduced pressure to 0.3 times the weight of the extract to obtain a water-extraction concentrate;

[0030] (2) add 70% ethanol of 10 times of weight in filter residue, carry out homogenization with high-speed homogenizer again, then slurry is carried out countercurrent ultrasonic extraction, collect alcohol extract after filtering (the condition of high-speed homogenization and countercurrent ultras...

Embodiment 3

[0034] A kind of preparation method of extract for black pulin tobacco, comprises the following steps:

[0035] (1) After the black bulin is washed, add 5 times the weight of water, homogenate for 10 minutes with a high-speed homogenizer with a rotating speed of 20,000 rpm, and then carry out countercurrent ultrasonic extraction of the slurry, the ultrasonic frequency is 100KHz, and the ultrasonic power is 200W, the extraction time is 30min, and the extraction temperature is 30°C. After filtration, the extract and filter residue are collected, and the extract is concentrated under reduced pressure to 0.1 times the weight of the extract to obtain a water-extraction concentrate;

[0036] (2) Add 5 times the weight of 90% ethanol to the filter residue, homogenize again with a high-speed homogenizer, then carry out countercurrent ultrasonic extraction of the slurry, and collect the alcohol extract after filtration;

[0037] (3) The water extraction concentrate of step (1) is combi...

Abstract

The invention discloses a preparation method of black pulin tobacco extract, which comprises the steps of high-speed homogenization of black pulin, countercurrent ultrasonic extraction with water and ethanol, alcohol precipitation and membrane separation of the extract, and the like. The method can improve the extraction efficiency of the active components of the Heibulin extract, reduce impurity components, and does not require complicated enzymolysis and fermentation treatment, the production cycle is short, and the cost is low. The obtained extract can significantly improve the aroma of cigarettes, reduce the The smoke is irritating and miscellaneous, and it is well coordinated with the smoke, and the aroma is good.

Description

technical field [0001] The technical field of the tobacco additive of the present invention, in particular relates to a preparation method of the extract of Heibulin tobacco. Background technique [0002] Hei Bulin, also known as Hei Brun or black plum, belongs to the genus Prunus in the Rosaceae. The fruit of Heibulin has a sweet taste and a strong fruity taste, and is rich in sugar, vitamins, fruit acids, amino acids and other nutrients. It is a common raw material in tobacco additives. [0003] CN103881815A discloses a black pulin extract, which is obtained after extraction, enzymolysis, enzyme-inactivation treatment, column chromatography separation and concentration of black pulin. Spraying the extract into the tobacco material can improve the internal quality of the cigarette, improve the aroma quality, make the smoke soft, fine and sweet, basically produce no miscellaneous gas, basically no stimulation and have a clean and comfortable aftertaste. [0004] The existi...
