Technical Field

The invention belongs to the technical field and relates to a preparation method of a guarana extract for cigarettes.

Background

Guarana is native to amazon drainage basin in south America, has the effects of refreshing and restoring consciousness, reducing fatigue, nourishing yin and tonifying yang, recovering physical strength, supplementing energy and building body, contains caffeine capable of gradually and slowly stimulating nerves, has long effective period of stimulation maintenance, is mild in stimulation and has no harm to human bodies. Therefore, the guarana extract is widely applied to food health care beverages, cigarettes and cosmetics, and the existing guarana extract comprises an alcohol extraction method, a water extraction method and an ethanol microwave extraction method, wherein an ethanol organic solvent is selected as an extraction solvent in the solvent extraction method, so that the extraction rate is low, the cost is high, and the industrial production requirements cannot be met.

Disclosure of Invention

The invention provides a preparation method of a guarana extract for cigarettes, and solves the problems of low recovery rate and high cost of the preparation method of the guarana extract in the prior art.

The technical scheme of the invention is realized as follows: a preparation method of a guarana extract for cigarettes comprises the following steps:

s1: purifying the guarana fruits: cleaning the guarana, then crushing and placing the guarana in a tank, and adding a soaking solution which is 9-10 times of the mass of the guarana, wherein the soaking solution comprises the following components in percentage by mass (15-22): 3: (3-8) ultrasonically leaching dichloromethane, tetraethyl orthosilicate and rhamnolipid, and filtering to obtain a leaching solution;

s2: adding extract liquor into the leaching liquor for extraction, wherein the volume ratio of the extract liquor to the leaching liquor is (0.4-0.7): 1, taking the upper layer, and filtering to obtain a guarana filtrate;

s3: and drying the guarana filtrate to obtain the guarana extract for the cigarettes.

Furthermore, the ultrasonic leaching time is 20-40min, the leaching temperature is 25-45 ℃, and the ultrasonic power is 300-400 w.

Further, the extraction temperature is 30-45 ℃, and the extraction time is 0.5-1 h.

Further, the drying temperature is 70-90 ℃, and the drying time is 1-1.5 h.

Further, the extraction liquid comprises the following components in a mass ratio of 1: (1-1.5): (5-6) octylphenol polyoxyethylene ether, sorbitol and 25% mass fraction sodium sulfate aqueous solution.

The working principle and the beneficial effects of the invention are as follows:

1. the extraction method is combined with the extraction method, compared with the existing alcohol extraction method, the extraction time is short, the extraction rate is high, and the content of caffeine, amino acid and tannin in the guarana extract is obviously improved.

2. In the invention, the extraction rate of caffeine in the guarana extract is improved by the mutual cooperation and synergy of dichloromethane, tetraethyl orthosilicate and rhamnolipid in the guarana soaking solution.

3. In the extraction liquid, the cigarette is prepared from the obtained extract through the mutual matching action of the octyl phenol polyoxyethylene ether, the sorbitol and the 25 mass percent sodium sulfate aqueous solution, the cigarette has elegant and natural fragrance, is sweet and comfortable, and has obvious baking fragrance, and the cigarette prepared from the extract which is not obtained from the extraction liquid has insufficient sweetness, less dry and plump smoke and stimulation to the throat.
