Embodiment 1

[0028] This embodiment discloses a method for preparing an extract for heat-not-burn cigarettes using Burley tobacco as a raw material. The specific steps are as follows:

[0029] (1) Extraction: after pulverizing the raw material with a mass of m, pass it through a 40-mesh sieve, mix it with an alcohol solution (90%, v / v) with a mass of 7 m, and extract at 55°C for 1 hour; after extraction, the solid-liquid separation, the liquid Filter to obtain tobacco extract.

[0030] (2) Concentration: the tobacco extract is concentrated under reduced pressure to a solid content of 60% at 60°C to obtain a tobacco alcohol paste; the cooling temperature is 0°C to recover the alcohol.

[0031] (3) Alkalinization extraction: add 2n NaOH solution (pH 12) to n tobacco alcohol paste, stir for 5 min; then mix with 2n petroleum ether, extract for 1 h.

[0032] (4) Refining: the extract is separated, the organic phase is taken, and concentrated under reduced pressure at 50°C until no petroleum et...

Embodiment 2

[0035] This example discloses a method for preparing an extract for heat-not-burn cigarettes from tobacco raw materials in Zhaotong, Yunnan. The specific steps are as follows:

[0036] (1) Extraction: After pulverizing the raw material with a mass of m, pass through a 60-mesh sieve, mix with an alcohol solution (95%, v / v) with a mass of 8 m, and extract at 60° C. for 1.5 h; after extraction, solid-liquid separation, The liquid is filtered to obtain tobacco extract.

[0037] (2) Concentration: Tobacco extract is concentrated under reduced pressure at 65°C to a solid content of 70% to obtain tobacco alcohol paste; the cooling temperature is -10°C to recover alcohol.

[0038] (3) Alkalinization extraction: add 3n NaOH solution (pH value 12) to tobacco alcohol paste with mass n, stir for 5 min; then mix with dichloromethane with mass n, and extract for 2 h.

[0039] (4) Refining: the extract is separated, the organic phase is taken, and concentrated under reduced pressure at 40°C...

Embodiment 3

[0042] This example discloses a method for preparing an extract for heat-not-burn cigarettes from tobacco raw materials in Yuxi, Yunnan. The specific steps are as follows:

[0043] (1) Extraction: After pulverizing the raw materials with a mass of m, pass through a 40-mesh sieve, mix with an alcohol solution (80%, v / v) with a mass of 10 m, and extract at 60° C. for 1.5 h; after extraction, solid-liquid separation, The liquid is filtered to obtain tobacco extract.

[0044] (2) Concentration: the tobacco extract is concentrated under reduced pressure at 70°C to a solid content of 55% to obtain a tobacco alcohol paste; the cooling temperature is 0°C, and the alcohol is recovered.

[0045] (3) Alkalinization extraction: add 2n NaOH solution (pH value 13) to n tobacco alcohol paste, stir for 10 min; then mix with 2n n-hexane, and extract for 1 h.

[0046] (4) Refining: the extract is separated, the organic phase is taken, and concentrated under reduced pressure at 50°C until no n-...

Abstract

The invention provides an extract for heat-not-burn cigarettes and a preparation method thereof. The preparation method for the extract of heat-not-burn cigarettes of the present invention comprises the following steps: mixing and extracting pulverized tobacco raw materials with an alcohol solution, After leaching, solid-liquid separation is obtained to obtain an extract, and the extract is filtered to obtain a tobacco extract; the tobacco extract is concentrated under reduced pressure to obtain a tobacco alcohol paste; lye is added to the tobacco alcohol paste, and after stirring evenly, it is mixed with an organic solvent for extraction. Extraction: After extraction, liquid separation is obtained to obtain an organic phase and an aqueous phase, and the organic phase is concentrated under reduced pressure, and the obtained essential oil product is an extract for heat-not-burn cigarettes. The nicotine content of the heat-not-burn cigarette extract prepared by the invention is higher than that of conventional tobacco extracts, and has obvious tobacco aroma and strength. The extract of the present invention can be used as an e-liquid component and added in a small amount to heat-not-burn cigarettes, that is, to meet the requirement of cigarettes to retain the original aroma and strength of tobacco.

Description

technical field [0001] The invention relates to tobacco technology, in particular to an extract used for heat-not-burn cigarettes and a preparation method thereof. Background technique [0002] Heat-not-burn cigarettes are a new type of cigarette product that has emerged in recent years. The key substances of the core material are mainly composed of e-liquid, smoking agent and humectant. Heating the core material at around 350°C can obtain an experience similar to smoking traditional cigarettes. Since the content of harmful substances in the smoke can be reduced and there is no open flame, heat-not-burn cigarettes have gradually become the focus of the development of China's tobacco industry. [0003] At present, there are different styles of heat-not-burn cigarettes popular on the market, and e-liquid determines the style of cigarettes. E-liquid is generally composed of a mixture of various natural flavor extracts and tobacco extracts. The former is mainly extracted from ...
