Problems solved by technology

During the ultrafiltration process, due to the continuous accumulation of trapped impurities such as amino acids, proteins, polysaccharides and macromolecular inorganic substances on the membrane surface, concentration polarization will occur. When the concentration of impurities on the membrane surface reaches a certain limit, condensation will be formed. The adhesive layer makes the permeability of the membrane drop sharply, which greatly limits the application of ultrafiltration

Embodiment 1

[0027] A preparation method for smoked sour plum extract, which comprises the following steps:

[0028] (1) Ultrasonic countercurrent extraction: clean the fresh sour plums, add 8 times of 60% ethanol by weight to the sour plums, soak for 2 hours at a temperature of 40°C, and then perform ultrasonic countercurrent extraction. The ultrasonic frequency is 60KHz, the temperature is 40°C, and the extraction time is 60min;

[0029] (2) Alcohol precipitation: filter the obtained extract, collect the filtrate and concentrate under reduced pressure to form an extract with a relative density of 1.2, then add 4 times of 95% ethanol by weight to the extract, fully stir and let stand for 10 hours;

[0030] (3) Membrane separation: take the supernatant after alcohol precipitation, and centrifuge at 6000 rpm to remove insoluble impurities. The centrifugate is first filtered with a ceramic microfiltration membrane with a pore size of 0.45 μm, and then 0.06% by weight is added to the filtrate...

Embodiment 2

[0033] A preparation method for smoked sour plum extract, which comprises the following steps:

[0034] (1) Ultrasonic countercurrent extraction: clean the fresh sour plums, add 5 times of 80% ethanol by weight to the sour plums, soak for 3 hours at a temperature of 30°C, and then perform ultrasonic countercurrent extraction. The ultrasonic frequency is 50KHz, the temperature is 50°C, and the extraction time is 30min;

[0035] (2) Alcohol precipitation: filter the obtained extract, collect the filtrate and concentrate under reduced pressure to form an extract with a relative density of 1.15, then add 3 times of 95% ethanol by weight to the extract, fully stir and let stand for 8 hours;

[0036] (3) Membrane separation: take the supernatant after alcohol precipitation, and centrifuge at a high speed of 5000 rpm to remove insoluble impurities. The centrifugate is first filtered with a ceramic microfiltration membrane with a pore size of 0.22 μm, and then 0.05% by weight is added...

Embodiment 3

[0039] A preparation method for smoked sour plum extract, which comprises the following steps:

[0040] (1) Ultrasonic countercurrent extraction: clean the fresh sour plums, add 10 times of 50% ethanol by weight to the sour plums, soak for 1 hour at a temperature of 50°C, and then perform ultrasonic countercurrent extraction. The ultrasonic frequency is 100KHz, the temperature is 30°C, and the extraction time is 90min;

[0041] (2) Alcohol precipitation: filter the obtained extract, collect the filtrate and concentrate under reduced pressure to form an extract with a relative density of 1.25, then add 5 times of 85% ethanol by weight to the extract, fully stir and let stand for 12 hours;

[0042] (3) Membrane separation: take the supernatant after alcohol precipitation, 10000 rpm high-speed centrifugation to remove insoluble impurities, first filter the centrifugate with a ceramic microfiltration membrane with a pore size of 1.5 μm, and then add 0.1% by weight to the filtrate ...

Abstract

The invention discloses a method for preparing cigarette-used smoked plum extract. The method includes the steps of ultrasonic countercurrent extraction of smoked plums, alcohol precipitation of condensed extract, membrane separation of supernatant after alcohol precipitation and condensation. The extraction efficiency of the smoked plum extract and smoking effect of the smoked plum extract in cigarettes are improved. Compared with common smoked plum extract, the extract prepared with the method is excellent in smoke compatibility, rich in fragrance and quality, low in irritation, less in impurities, and clean in aftertaste.

Description

technical field [0001] The invention belongs to the technical field of preparation of tobacco additives, and in particular relates to a preparation method of sour plum extract for tobacco. Background technique [0002] Sour plum, also known as green plum, contains a large amount of protein, fat, carbohydrates and various organic acids. The sour plum extract is a commonly used additive in cigarettes. CN104188089A discloses the application of greengage extract in cigarettes, which is obtained by soaking greengage in sorghum wine. The extract can effectively improve the quality of cigarettes and enhance the aroma of cigarettes. [0003] Most of the existing sour plum extracts are decocted or refluxed with water and alcohol. This preparation method not only has a low extraction efficiency of active ingredients, but also has many impurities, which affects the evaluation effect of cigarettes. [0004] Membrane separation technology is an emerging high-efficiency separation techno...
