Embodiment 1

[0029] Weigh 10g of PEG-400 and place it in a flask, add 100g of methanol, fully dissolve it in a water bath at 25°C and mix evenly to obtain a methanol solution containing PEG-400. Weigh 3.33g of edible paraffin, heat the paraffin to melt it completely, add 10g of vitamin C while it is hot and stir evenly to obtain a mixture of vitamin C and edible paraffin. Add the obtained vitamin C and edible paraffin mixture to the PEG methanol solution while hot, and keep stirring at 70°C for 30 minutes. Heating and stirring were stopped, and the mixture was naturally cooled to room temperature under reflux to obtain a suspension containing solids. After the suspension was completely cooled, the supernatant was removed by filtration, and the obtained solid was rinsed with methanol for 3 to 5 times, dried under reduced pressure, and then freeze-dried to obtain 11 g of vitamin C microcapsules I.

Embodiment 2

[0031] Weigh 10g of PEG-400 and place it in a flask, add 250g of methanol, fully dissolve it in a water bath at 35°C and mix evenly to obtain a methanol solution containing PEG-400. Weigh 10 g of edible paraffin, heat the paraffin to melt it completely, add 20 g of vitamin C while it is hot and stir evenly to obtain a mixture of vitamin C and edible paraffin. Add the obtained vitamin C and edible paraffin mixture to the PEG methanol solution while hot, and keep stirring at 70°C for 60 minutes. Heating and stirring were stopped, and the mixture was naturally cooled to room temperature under reflux to obtain a suspension containing solids. After the suspension was completely cooled, the supernatant was removed by filtration, and the obtained solid was rinsed with methanol for 3 to 5 times, dried under reduced pressure, and then freeze-dried to obtain 17 g of vitamin C microcapsule II.

Embodiment 3

[0033] Weigh 10g of PEG-400 and place it in a flask, add 150g of methanol, fully dissolve it in a water bath at 30°C and mix evenly to obtain a methanol solution containing PEG-400. Weigh 5 g of edible paraffin, heat the paraffin to melt it completely, add 15 g of vitamin C while it is hot and stir evenly to obtain a mixture of vitamin C and edible paraffin. Add the obtained vitamin C and edible paraffin mixture to the PEG methanol solution while hot, and keep stirring at 70°C for 45 minutes. Heating and stirring were stopped, and the mixture was naturally cooled to room temperature under reflux to obtain a suspension containing solids. After the suspension was completely cooled, the supernatant was removed by filtration, and the obtained solid was rinsed with methanol for 3 to 5 times, dried under reduced pressure, and then freeze-dried to obtain 19 g of vitamin C microcapsules.

Abstract

The invention discloses a preparing method of a vitamin C microcapsule and application of the vitamin C microcapsule in cigarette. Firstly PEG is dissolved by methyl alcohol to obtain a PEG-methyl alcohol solution, then paraffin is heated to be dissolved, vitamin C is added to obtain a mixture of vitamin C and edible paraffin, the obtained mixture of vitamin C and edible paraffin is added into the PEG-methyl alcohol solution while the mixture is hot, the solution is heated and stirred at a certain temperature, and cooled to the room temperature, filtering is conducted to remove liquid supernatant, the product is washed with a solvent, and is firstly dried under a reduced pressure, and then frozen to be dried to obtain the needed vitamin C microcapsule. After being applied to the cigarette, the vitamin C microcapsule can play an effect of improving cigarette smoke irritation, improving the mouthfeel, and improving the cigarette comfort; meanwhile, the preparing method is simple in technology and equipment, low in cost and small in contamination.

Description

technical field [0001] The invention belongs to the technical field of cigarette additives, and in particular relates to a preparation method of vitamin C microcapsules, and meanwhile, the invention also relates to the application of the vitamin C microcapsules in cigarettes. Background technique [0002] With the rapid development of science and technology and the continuous improvement of people's health awareness, low-tar cigarettes have gradually become an important development direction of the tobacco industry. Make up for these losses without increasing the amount of tar produced. The design of the flavor and fragrance formula of cigarette products is very important. Through the design and optimization of the formula, it can supplement and modify the flavor of cigarettes, thereby improving the sensory quality of cigarette products. [0003] At present, many tobacco flavors are highly volatile, easily oxidized or easily decomposed when exposed to light and heat in the ...
