Embodiment 1

[0032] This embodiment discloses a method for preparing a high-nicotine tobacco extract from tobacco raw materials in Qujing, Yunnan. The specific steps are as follows:

[0033] (1) After pulverizing the raw material with a mass of m, pass through a 40-mesh sieve; add 0.3% m pectinase (enzyme activity: 50,000 U) and 0.2% m cellulase in water with a quality of 1.5 m (Enzyme activity: 100,000 U), mix with raw materials after uniform stirring, and carry out enzymolysis reaction; the time of enzymolysis reaction is 3 hours, and the temperature is 50°C.

[0034] (2) Mix the enzymatically hydrolyzed material with 7m ethanol solution (90%, v / v), extract at 55°C for 1 hour; separate solid from liquid after extraction, and filter the liquid to obtain tobacco extract.

[0035] (3) concentrating the tobacco extract under reduced pressure to a solid content of 60% at 65° C. to obtain a tobacco alcohol extract; the cooling temperature is 0° C. to recover ethanol.

Embodiment 2

[0040] This embodiment discloses a method for preparing a high-nicotine tobacco extract from tobacco raw materials in Zhaotong, Yunnan. The specific steps are as follows:

[0041] (1) after the raw material that quality is m is pulverized, cross 60 mesh sieves; In the water that quality is 2m, add the pectinase (enzyme activity: 50,000 U) that quality is 0.4% m and the cellulase ( Enzyme activity: 100,000 U), mix with raw materials after uniform stirring, and carry out enzymolysis reaction; the time of enzymolysis reaction is 2.5h, and the temperature is 55°C.

[0042] (2) Mix the enzymatically hydrolyzed material with 8m ethanol solution (95%, v / v), extract at 55°C for 2h; separate the solid and liquid after extraction, and filter the liquid to obtain tobacco extract.

[0043] (3) concentrating the tobacco extract under reduced pressure to a solid content of 60% at 70° C. to obtain a tobacco alcohol extract; the cooling temperature is 0° C. to recover ethanol.

Abstract

The invention provides a high-nicotine tobacco extract, a preparation method thereof and a heat-not-burn cigarette, and the preparation method of the high-nicotine tobacco extract comprises the following steps: mixing crushed tobacco raw materials with water, and adding an enzyme preparation for treatment; mixing the treated tobacco raw material with a high-concentration ethanol solution for leaching, performing solid-liquid separation after leaching to obtain a leaching solution, and filtering the leaching solution to obtain a tobacco clear solution; concentrating the tobacco clear liquid under reduced pressure to obtain a tobacco alcohol extract; adding alkali liquor into the tobacco alcohol extract, uniformly stirring, and mixing with an organic solvent for extraction; separating liquidafter extraction to obtain an organic phase and a water phase, and concentrating the organic phase under reduced pressure to obtain a product, namely the high-nicotine tobacco extract. The nicotine content of the prepared high-nicotine tobacco extract is higher than that of a conventional tobacco extract, and the high-nicotine tobacco extract has obvious tobacco fragrance and strength. The heat-not-burn cigarette added with a small amount of high-nicotine tobacco extract is rich in tobacco fragrance and strength.

Description

technical field [0001] The invention relates to tobacco technology, in particular to a high-nicotine tobacco extract, a preparation method thereof and a heat-not-burn cigarette. Background technique [0002] Heat-not-burn cigarettes are a new type of tobacco product. Reconstituted tobacco leaf sheets are used as pods. After heating the pods within the temperature range of 200-300°C, aerosols containing nicotine and other compounds are produced, satisfying the experience similar to smoking traditional cigarettes. sense, more and more attention has been drawn to the tobacco market. [0003] At present, there are different styles of heat-not-burn cigarettes popular in the market, and the coating liquid of the pod is mainly composed of various tobacco flavors, so the cigarette style depends on the tobacco flavors. Tobacco spices are generally composed of various natural flavor extracts and tobacco extracts. The former, such as jujube tincture and apricot juice, are extracted fr...
