Embodiment 1

[0023] Under the protection of nitrogen, the five-membered cucurbit ring and hydroxypropyl cellulose were added to ethanol and n-hexane, wherein the volume ratio of ethanol to n-hexane was 10:1, and the five-membered cucurbit ring and hydroxypropyl cellulose mass The ratio is 1:2, heat to 90°C, keep for 2.5h, then add sodium hydroxide solution, adjust the pH value to 10, stir well, cool at room temperature, filter, wash the precipitate with water, dry to obtain the melon ring additive.

[0024] Take by weighing a certain amount of melon ring additive, add in the tip stick with 10mg / cigarette, make the embodiment cigarette that filter tip contains additive of the present invention, do comparative experiment with comparative example, embodiment cigarette except containing different additives, other Such as materials and auxiliary materials, size specifications, mouth sticks, etc. are all identical to the comparative cigarettes.

Embodiment 2

[0026] Under the protection of nitrogen, the decamethyl five-membered cucurbit ring and hydroxypropyl cellulose were added to ethanol and n-hexane (v / v=5:1), in which the decamethyl five-membered cucurbit ring and hydroxypropyl cellulose The mass ratio is 1:1, heat to 118°C, keep for 5h, then add potassium hydroxide solution, adjust the pH value to 11, stir well, cool at room temperature, filter, wash the precipitate with water, dry to obtain the melon ring additive.

[0027] Take by weighing a certain amount of melon ring additive, add in the tip stick with 10mg / cigarette, make the embodiment cigarette that filter tip contains additive of the present invention, do comparative experiment with comparative example, embodiment cigarette except containing different additives, other Such as materials and auxiliary materials, size specifications, mouth sticks, etc. are all identical to the comparative cigarettes.

Embodiment 3

[0029] Under nitrogen protection, add ten-membered cucurbit rings and hydroxypropyl cellulose to ethanol and n-hexane, wherein the volume ratio of ethanol to n-hexane is 8:1, and the mass of ten-membered cucurbit rings and hydroxypropyl cellulose The ratio is 1:0.4, heat to 70°C, keep for 1h, then add potassium hydroxide solution, adjust the pH value to 10, stir well, cool at room temperature, filter, wash the precipitate with water, dry to obtain the melon ring additive.

[0030] Mix mint, chamomile, honeysuckle, and gardenia, add 5 times the amount of water, heat and extract at 80°C, collect the filtrate, concentrate under reduced pressure, take 500ml of the concentrate, add 20mg of cucurbitan additive, stir and let it stand for 1-2h, filter , wash with precipitation, after drying, take by weighing 10mg / support and add in the cigarette tip rod, make the embodiment cigarette that filter tip contains additive of the present invention, do comparative experiment with comparative...

Abstract

The invention belongs to the technical field of tobacco additives, and discloses a cucurbituril additive for reducing harm and enhancing aroma of cigarettes and a preparation method of the cucurbituril additive. Under protection of inert gas, cucurbituril and hydroxy propyl cellulose are added into ethyl alcohol and normal hexane (v / v=10:(1-5):1) and heated to reach the temperature of 70-118 DEG C, the temperature is kept for 1-5 hours, alkaline solution is added, a pH (potential of hydrogen) value is adjusted to range from 10 to 11, and the materials are uniformly stirred, cooled at room temperature, filtered, washed by precipitation water and dried to obtain the cucurbituril additive. The prepared cucurbituril additive can be added into a cigarette filter and is high in stability and applicable to industrial application, the tar content and other harmful substances of the cigarettes are effectively reduced, and harmful offensive odor cannot be led in.

Description

technical field [0001] The invention belongs to the technical field of tobacco additives, and in particular relates to a melon ring additive for reducing harm and increasing flavor of cigarettes and a preparation method thereof. Background technique [0002] At present, with the continuous improvement of people's health awareness, cigarette consumers have higher and higher requirements for low-harm cigarette products. Adsorption materials are added to filter rods to reduce tar and harm by using its large specific surface and strong adsorption capacity. It is a common and effective method in the tobacco industry at home and abroad in recent years. However, there are still many problems in the filters made of these adsorption materials. For example, commonly used inorganic adsorption materials, such as silica gel, diatomaceous earth, zeolite, porous ceramics, and activated carbon Etc., the hardness is relatively high, and in the process of filter rod and cigarette production, ...
